| Summary of significant accounting policies | Note 3 – Summary of significant accounting
policies Basis of presentation The accompanying financial statements have been
prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for information
pursuant to the rules and regulations of the SEC. Use of estimates and assumptions The preparation of financial statements in conformity
with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the
balance sheet date and revenues and expenses during the reporting periods. Significant accounting estimates reflected in the Company’s
financial statements include, but not limited to, estimates for useful lives and impairment of property and equipment, impairment of long-lived
assets, allowance for expected credit loss, revenue recognition, and deferred taxes. Changes in facts and circumstances may result in
revised estimates. Actual results could differ from those estimates, and as such, differences may be material to the financial statements. Foreign currency translation and transaction The Company uses Japanese yen (“JPY”)
as its reporting currency. The functional currency of the Company which is incorporated in Japan is JPY, which is its respective local
currency based on the criteria of ASC 830, “Foreign Currency Matters”. Foreign currency transactions denominated in currencies other than
the functional currency are translated into the functional currency using the exchange rates prevailing at the dates of the transactions.
Monetary assets and liabilities denominated in foreign currencies are translated into the functional currency using the applicable exchange
rates at the balance sheet dates. Net gains and losses resulting from foreign exchange transactions are included in exchange gain (loss),
net on the statements of operations. Convenience Translation Translations of balances in the balance sheets,
statements of operations, statements of changes in shareholders’ equity and statements of cash flows from JPY into USD as of April
30, 2024 are solely for the convenience of the readers and are calculated at the rate of USD 1.00=JPY157.54, representing the exchange
rate set forth in the H.10 statistical release of the Federal Reserve Board on April 30, 2024. No representation is made that the JPY
amounts could have been, or could be, converted, realized or settled into USD at such rate, or at any other rate. Reclassifications Certain reclassifications to previously reported
financial information have been made to conform to the current period presentation. Cash Cash includes currency on hand and deposits held
by banks that can be added or withdrawn without limitation. The Company maintains its bank accounts in Japan and the United States. Cash
balances in bank accounts in Japan are insured by the Deposit Insurance Corporation of Japan subject to certain limitations. Cash balances
in bank accounts in the United States are insured by the Federal Deposit Insurance Corporation up to USD250,000 Restricted cash Restricted cash is cash legally restricted as
to withdrawal or usage due to an order by the Tokyo District Court as a result of a lawsuit filed by certain shareholders of the Company. Time deposit Time deposit is a deposit in a bank account with
original maturity of over three months. The Company purchased a time deposit of JPY100,000,000 on April 26, 2024 and the maturity is set
on July 31, 2024. The interest rate is set at 0.025% per annum. Digital assets Digital assets such as Ethereum, Binance Coin
and Polygon are included in current assets in the balance sheets as an indefinite live intangible asset. Digital assets are initially
recognized based on the fair value of the digital assets on the date of receipt. The Company recognized realized gains or losses when
digital assets are sold for other digital assets, or for cash consideration using a first-in first-out method of accounting and the Company
accounts for received and disbursements as cash flows from operating activities. An intangible asset with an indefinite useful
life is not amortized but assessed for impairment whenever events or changes in circumstances occur indicating that it is more likely
than not that the indefinite-life asset is impaired. Impairment exists when the carrying amount exceeds its fair value, which is measured
using the quoted price of the digital assets in the principal market at the time its fair value is being measured, and the Company recognized
an impairment loss in an amount equal to that excess. The Company monitors and evaluates the quality and relevance of the available information,
such as pricing information from the asset’s principal (or most advantageous) market or from other digital asset exchanges or markets,
to determine whether such information is indicative of a potential impairment. The Company recognizes an impairment loss at any time the
fair value of the digital asset is below its carrying value. To the extent an impairment loss is recognized, the loss establishes the
new cost basis of the asset. Subsequent reversal of impairment losses is not permitted. Accounts receivable and allowance for expected credit losses accounts Accounts receivable include trade accounts due from clients. As of
May 1, 2022, accounts receivable, net was JPY72,259,707. Accounts are considered overdue after 90 days. The Company considers various
factors in establishing, monitoring, and adjusting its allowance for credit losses including the aging of receivables and aging trends,
customer creditworthiness and specific exposures related to particular customers. The Company also monitors other risk factors and forward-looking
information, such as country specific risks and economic factors that may affect a customer’s ability to pay in establishing and
adjusting its allowance for credit losses. Account balances are charged off against the allowance after all means of collection have been
exhausted and the likelihood of collection is not probable. As of May 1, 2022, April 30, 2023 and 2024, the Company had nil nil nil Prepayments Prepayments are mainly payments made to vendors
or services providers for future services that have not been provided. These amounts are refundable and bear no interest. Management reviews
its prepayments on a regular basis to determine if the allowance is adequate and adjusts the allowance when necessary. As of April 30,
2023 and 2024, no allowance was deemed necessary. Deferred initial public offering (“IPO”)
costs Pursuant to ASC 340-10-S99-1, IPO costs directly
attributable to an offering of equity securities were deferred and charged against the gross proceeds of the offering as a reduction
of additional paid-in capital. These costs included legal fees, consulting fees, underwriting fees, the SEC filing and printing expenses
related to the IPO. On July 27, 2023, the Company closed its IPO and gross proceeds of JPY781,200,000 (USD 4,958,738) were
recorded in ordinary shares and the accumulated deferred IPO costs of JPY326,330,981 (USD 2,071,414), consisting of JPY212,160,121 (USD 1,346,705)
incurred through April 30, 2023 and JPY114,170,860 (USD 724,709) incurred from May 1, 2023 to July 27, 2023 were charged against
additional paid-in capital in the balance sheet. Short-term deposits and long-term deposits Short-term deposits and long-term deposits are
mainly for rent and money deposited with certain service providers. These amounts are refundable and bear no interest. The short-term
deposits usually have one year term and are refundable upon contract termination. The long-term deposits are refunded from service providers
when term and conditions set forth in the agreements have been satisfied. Other current assets, net Other current assets, net, primarily consists
of other receivables from third parties. These other receivables are unsecured and are reviewed periodically to determine whether their
carrying value has become impaired. Property and equipment, net Property and equipment are stated at cost less
accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets. The estimated
useful lives are as follows:
Leasehold improvements lesser of lease term or expected useful life
Office furniture and fixtures 2 – 4 years The cost and related accumulated depreciation
of assets sold or otherwise retired are eliminated from the accounts and any gain or loss is included in the statements of operations.
Expenditures for maintenance and repairs are charged to earnings as incurred, while additions, renewals and betterments, which are expected
to extend the useful life of assets, are capitalized. Impairment for long-lived assets Long-lived assets, including property and equipment
and intangible assets with finite lives are reviewed for impairment whenever events or changes in circumstances (such as a significant
adverse change to market conditions that will impact the future use of the assets) indicate that the carrying value of an asset may not
be recoverable. We assess the recoverability of the assets based on the undiscounted future cash flows the assets are expected to generate
and recognize an impairment loss when estimated undiscounted future cash flows expected to result from the use of the asset plus net proceeds
expected from disposition of the asset, if any, are less than the carrying value of the asset. If an impairment is identified, we would
reduce the carrying amount of the asset to its estimated fair value based on a discounted cash flows approach or, when available and appropriate,
to comparable market values. For the years ended April 30, 2022, 2023 and 2024 no impairment of long-lived assets was recognized. Fair value of financial instruments Fair value is defined as the price that would
be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement
date. A three-level fair value hierarchy prioritizes the inputs used to measure fair value. The hierarchy requires entities to maximize
the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as
follows:
● Level
1 – inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets.
● Level
2 – inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, quoted market
prices for identical or similar assets in markets that are not active, inputs other than quoted prices that are observable, and inputs
derived from or corroborated by observable market data.
● Level
3 – inputs to the valuation methodology are unobservable. Unless otherwise disclosed, the fair value of the Company’s financial
instruments, including cash, time deposit, digital assets, accounts receivable, contract assets, prepayments, short-term deposits, income
tax receivable and other current assets, current portion of long-term bank loans, other payables and accrued liabilities, current operating
lease liabilities, income tax payable, and contract liabilities approximate the fair value of the respective assets and liabilities as
of April 30, 2023 and 2024 based upon the short-term nature of the assets and liabilities. Revenue recognition The Company recognizes revenue as it satisfies a performance obligation
when its client obtains control of promised goods or services, in an amount that reflects the consideration that the Company expects to
receive in exchange for those goods or services. To determine revenue recognition for arrangements that the Company determines are within
the scope of ASC Topic 606, Revenue from Contracts with Customers (“ASC 606”), the Company performs the following five steps:
(i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction
price, including variable consideration, if any; (iv) allocate the transaction price to the performance obligations in the contract; and
(v) recognize revenue when (or as) the Company satisfies a performance obligation. The Company only applies the five-step model to contracts
when it is probable that the Company will collect the consideration to which it is entitled in exchange for the goods or services it transfers
to the client. The Company applied practical expedient when sales
taxes were collected from clients, meaning sales tax is recorded net of revenue, instead of cost of revenue, which are subsequently remitted
to governmental authorities and are excluded from the transaction price. The Company does not offer rights of refund of previously paid
or delivered amounts, rebates, rights of return or price protection. In all instances, the Company limits the amount of revenue recognized
to the amounts for which it has the right to bill its clients. The Company is a principal and records revenue on a gross basis when
the Company is primarily responsible for fulfilling the service, has discretion in establishing pricing and controls the promised service
before transferring that service to clients. Otherwise, the Company is an agent and records revenue on a net basis. The Company derives its revenues from three sources: (1) software and
system development services, (2) consulting and solution services, and (3) sale of NFTs. All of the Company’s contracts with clients
do not contain cancellable and refund-type provisions. (1) Software and system development services The contract is typically fixed priced and does
not provide any post contract client support or upgrades. The Company designs software and system based on clients’ specific needs
which require the Company to perform services including design, development, and integration. These services also require significant
customization. Upon delivery of the services, client acceptance is generally required. The Company assesses that software and system development
services is considered as one performance obligation as the clients do not obtain benefit for each separate service. The duration of the
development period is short, usually less than one year. The Company’s software and system development
service revenue is generated primarily from contracts with medium and large-sized enterprises. The contracts contain negotiated billing
terms which generally include multiple payment phases throughout the contract term and a portion of contract amount usually is billed
upon the completion of the related projects. Pursuant to the contract terms, the Company has enforceable right on payments for the work
performed. The Company’s revenue from software and
system development contracts is generally recognized over time as the Company’s performance creates or enhances the project controlled
by the clients and the control is transferred continuously to the Company’s clients. The Company uses an input method based on cost
incurred as the Company believes that this method most accurately reflects the Company’s progress toward satisfaction of the performance
obligation, which usually takes less than one year. Under this method, the Company could appropriately measure the fulfillment of a performance
obligation. Assumptions, risks and uncertainties inherent in the estimates used to measure progress could affect the amount of revenues,
receivables and contract liabilities at each reporting period. Incurred costs include all direct material, labor
and subcontract costs, and those indirect costs related to application development performance, such as indirect labor, supplies, and
tools. Cost-based input method requires the Company to make estimates of revenues and costs to complete the service. In making such estimates,
significant judgment is required to evaluate assumptions related to the costs to complete the application development, including materials,
labor, and other system costs. The Company’s estimates are based upon the professional knowledge and experience of the Company’s
engineers and project managers to assess the contract’s schedule, performance, and technical matters. The Company has adequate cost
history and estimating experience, and with respect to which management believes it can reasonably estimate total development costs. If
the estimated costs are greater than the related revenues, the Company recognizes the entire estimated loss in the period the loss becomes
known and can be reasonably estimated. Changes in estimates for software development services include but are not limited to cost forecast
changes and change orders. The cumulative effect of changes in estimates is recorded in the period in which the revisions to estimates
are identified and the amounts can be reasonably estimated. To date, the Company has not incurred a material loss on any contracts. However,
as a policy, provisions for estimated losses on such engagements will be made during the period in which a loss becomes probable and can
be reasonably estimated. If contract modifications result in additional goods or services that are distinct from those transferred before
the modification, they are accounted for prospectively as if the Company entered into a new contract. If the goods or services in the
modification are not distinct from those in the original contract, sales and gross profit are adjusted using the cumulative catch-up method
for revisions in estimated total contract costs and contract values. (2) Consulting and solution services Revenue from consulting and solution services
is primarily comprised of fixed-fee contracts, which require the Company to provide professional consulting and solution services over
contract terms beginning on the commencement date of each contract, which is the date its service is made available to clients. Billings
to the clients are generally on a monthly or quarterly basis over the contract term, which is typically 1 to 12 months. The consulting
and solution services contracts typically include a single performance obligation. The revenue from consulting and solution services is
recognized over the contract term as clients receive and consume benefits of such services as provided. Revenue includes reimbursements of travel and
out-of-pocket expense, with equivalent amounts of expense recorded in cost of revenue. (3) Sale of NFTs The Company engages in sale of NFTs, or non-fungible
tokens. NFTs are assets that have been tokenized via a blockchain and are assigned unique identification codes and metadata that distinguish
them from other tokens. The Company typically enters into contracts with its customers where the rights of the parties, including payment
terms, are identified and sales prices to the customers are fixed with no separate sales rebate, discount, or other incentive and no right
of return exists on sales of NFTs. The Company’s performance obligation is to deliver products according to contract specifications.
The Company recognizes product revenue at a time when the control of products is transferred to customers. Contract balances The timing of revenue recognition may differ from
the timing of invoicing to customers. For certain services, customers are required to pay before the services are transferred. The Company
recognizes contract assets or contract liabilities in the balance sheets, depending on the relationship between the Company’s performance
and the customer’s payment. Contract assets are rights to consideration in
exchange for goods or services that the entity has transferred to a customer when that right is conditional on something other than the
passage of time. As of May 1, 2022, April 30, 2023 and 2024, the Company recorded contract assets of nil nil Contract liabilities are recorded when consideration
is received from a customer prior to transferring the services to the customer or other conditions under the terms of a sales contract.
As of May 1, 2022, April 30, 2023 and 2024, the Company recorded contract liabilities of nil nil Operating leases The Company determines if an arrangement is a lease at inception. Leases
are classified as operating or finance leases in accordance with the recognition criteria in ASC 842-20-25. The Company’s leases
do not contain any material residual value guarantees or material restrictive covenants. At the commencement date of a lease, the Company
determines the classification of the lease based on the relevant factors present and records a right-of-use (“ROU”) asset
and lease liability for operating lease. ROU assets acquired through lease represent the right to use an underlying asset for the lease
term, and operating lease liabilities represent the obligation to make lease payments arising from the lease. ROU assets and lease liabilities
are calculated as the present value of the lease payments not yet paid. If the rate implicit in the Company’s leases is not readily
available, the Company uses an incremental borrowing rate based on the information available at the lease commencement date in determining
the present value of lease payments. This incremental borrowing rate reflects the fixed rate at which the Company could borrow on a collateralized
basis the amount of the lease payments in the same currency, for a similar term, in a similar economic environment. ROU assets include
any lease prepayments and are reduced by lease incentives. Operating lease expense for lease payments is recognized on a straight-line
basis over the lease term. Lease terms are based on the non-cancellable term of the lease. Leases with an initial lease term of 12 months
or less are not recorded on the balance sheets. Lease expense for these leases is recognized on a straight-line basis over the lease term. Cost of revenues Cost of revenues mainly consist of salaries and
benefits of our staff and outsourced staff, and related expenses including telecommunication cost and rental costs. Selling and marketing expenses Selling and marketing expenses mainly consist
of payroll, promotion expenses, and related expenses for personnel engaged in selling and marketing activities. Advertising expenses Advertising costs are expensed as incurred and
included in selling, general, and administrative expenses in the statements of operations. Advertising expenses amounted to JPY230,000,
JPY25,599,131, and JPY18,026,395 (USD114,424) for the years ended April 30, 2022, 2023 and 2024, respectively. Research and development expenses Research and development costs are expensed as
incurred. These costs primarily consist of payroll, outsourced development cost, and related expenses for personnel engaged in research
and development activities. Income taxes The Company accounts for current income taxes
in accordance with the laws of the relevant tax authorities. Deferred income taxes are recognized when temporary differences exist between
the tax bases of assets and liabilities and their reported amounts in the financial statements. Deferred tax assets and liabilities are
measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to
be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period
including the enactment date. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected
to be realized. An uncertain tax position is recognized as a benefit
only if it is “more likely than not” that the tax position would be sustained in a tax examination. The amount recognized
is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the
“more likely than not” test, no tax benefit is recorded. Penalties and interest incurred related to underpayment of income
tax are classified as income tax expense in the period incurred. No significant penalties or interest relating to income taxes were incurred
during the years ended April 30, 2022, 2023 and 2024. The Company does not believe there was any uncertain tax provision as of April 30,
2023 and 2024. Loss per share Basic loss per share is computed by dividing
net loss attributable to the holders of ordinary shares by the weighted average number of ordinary shares outstanding during the period
presented. Diluted loss per share is calculated by dividing net loss attributable to the holders of ordinary shares as adjusted for the
effect of dilutive ordinary share equivalents, if any, by the weighted average number of ordinary shares and dilutive ordinary share
equivalents outstanding during the period. However, ordinary share equivalents are not included in the denominator of the diluted loss
per share calculation when inclusion of such shares would be anti- dilutive, such as in a period in which a net loss is recorded. Share-based compensation The Company applies ASC 718, Compensation –
Stock Compensation Compensation-Stock Compensation (Topic 718): Improvement to Employee Share-based Payment Accounting Segment reporting ASC 280, “Segment Reporting”, establishes
standards for reporting information about operating segments on a basis consistent with the Company’s internal organizational structure
as well as information about geographical areas, business segments and major clients in financial statements for detailing the Company’s
business segments. Based on the criteria established by ASC 280, the Company’s chief operating decision maker (“CODM”)
has been identified as the Chief Executive Officer, who reviews results when making decisions about allocating resources and assessing
performance of the Company. As a whole and hence, the Company has only one reportable segment. The Company does not distinguish between
markets or segments for the purpose of internal reporting. As the Company’s long-lived assets are substantially located in Japan,
no geographical segments are presented. Related party transactions A related party is generally defined as (i) any
person and or their immediate family who hold 10% or more of the company’s securities (ii) the Company’s management, (iii)
someone that directly or indirectly controls, is controlled by or is under common control with the Company, or (iv) anyone who can significantly
influence the financial and operating decisions of the Company. A transaction is considered to be a related party transaction when there
is a transfer of resources or obligations between related parties. Related parties may be individuals or corporate entities. Transactions involving related parties cannot
be presumed to be carried out on an arm’s-length basis, as the requisite conditions of competitive, free market dealings may not
exist. Representations about transactions with related parties, if made, shall not imply that the related party transactions were consummated
on terms equivalent to those that prevail in arm’s-length transactions unless such representations can be substantiated. It is not,
however, practical to determine the fair value of amounts due from/to related parties due to their related party nature. Commitments and Contingencies In the normal course of business, the Company
is subject to contingencies, including legal proceedings and claims arising out of the business that relate to a wide range of matters,
such as government investigations and tax matters. The Company recognizes a liability for such contingency if it determines it is probable
that a loss has occurred and a reasonable estimate of the loss can be made. The Company may consider many factors in making these assessments
including historical performance and the specific facts and circumstances of each matter. Risks and uncertainties Political and economic risk All of the Company’s assets were located
in Japan and all of the Company’s revenue was generated in Japan. Accordingly, the Company’s business, financial condition,
and results of operations may be influenced by political, economic, and legal environments in Japan, as well as by the general state of
Japan economy. The Company’s results may be adversely affected by changes in the political, regulatory, and social conditions in
Japan. Although the Company has not experienced losses from these situations and believes that it is in compliance with existing laws
and regulations, including its organization and structure disclosed in Note 1, such experience may not be indicative of future results. Foreign currency exchange risk The functional currency of the Company is JPY.
Exposure to foreign currency risk is derived from a bank account denominated in US dollars. Our financial position, results of operations
and cash flow are, therefore, subject to fluctuations due to changes in foreign currency exchange rates and may be adversely affected
in the future due to changes in foreign currency exchange rates. To date, we have not engaged in hedging our foreign
currency exchange risk. In the future, we may enter into formal currency hedging transactions to decrease the risk of financial exposure
from fluctuations in the exchange rates of our principal operating currencies. These measures, however, may not adequately protect us
from the adverse effects of such fluctuations. Credit risk As of April 30, 2023 and 2024, JPY177,886,393 and JPY469,397,355 (USD2, 979,544 Accounts receivables are typically unsecured and
derived from revenue earned from customers, thereby exposed to credit risks. The risk is mitigated by the Company’s assessment of
its customers’ creditworthiness and its ongoing monitoring of outstanding balances. Concentration of credit risk Financial instruments that potentially expose
the Company to concentrations of credit risk consist primarily of cash and cash equivalents and account receivable. The Company places
its cash with financial institutions with high-credit ratings and quality. Accounts receivable primarily comprise of amounts
receivable from the service clients. To reduce credit risk, the Company performs on-going credit evaluations of the financial condition
of these service clients. The Company establishes a provision for credit losses based upon estimates, factors surrounding the credit risk
of specific service clients and other information. Concentration of demand As of April 30, 2023, one client accounted for
97.7% of the Company’s total accounts receivable. As of April 30, 2024, one client accounted for 98.6% of the Company’s
total accounts receivable. For the year ended April 30, 2022, two major clients
accounted for 47.4% and 25.9% of the Company’s total revenues, respectively. For the year ended April 30, 2023, three major clients
accounted for 42.9%, 24.1% and 10.5% of the Company’s total revenues, respectively. For the year ended April 30, 2024, three major
clients accounted for 42.6%, 27.2% and 21.5% of the Company’s total revenues, respectively. Concentration of supply As of April 30, 2023, three vendors accounted
for 15.2%, 15.0% and 10.6% of the Company’s total account payable. As of April 30, 2024, two vendors accounted for 33.3% and 14.9%
of the Company’s total account payable. For the year ended April 30, 2022, three vendors
accounted for 29.3%, 25.6% and 14.9% of the Company’s total purchases. For the year ended April 30, 2023, two vendors accounted
for 73.8% and 23.3% of the Company’s total purchases. For the year ended April 30, 2024, two vendors accounted for 50.7% and 44.0%
of the Company’s total purchases, respectively. Recent accounting pronouncements The Company considers the applicability and impact
of all accounting standards updates (“ASUs”). Management periodically reviews new accounting standards that are issued. Under
the Jumpstart Our Business Startups Act of 2012, as amended (the “JOBS Act”), the Company meets the definition of an emerging
growth company, or EGC, and has elected the extended transition period for complying with new or revised accounting standards, which delays
the adoption of these accounting standards until they would apply to private companies. In June 2016, the FASB amended guidance related
to the impairment of financial instruments as part of ASU2016-13 Financial Instruments – Credit Losses (Topic 326): Measurement
of Credit Losses on Financial Instruments, which will be effective January 1, 2020. The guidance replaces the incurred loss impairment
methodology with an expected credit loss model for which a company recognizes an allowance based on the estimate of expected credit loss.
In November 2018, the FASB issued ASU No. 2018-19, Codification Improvements to Topic 326, Financial Instruments – Credit Losses,
which clarified that receivables from operat |
