| Nature of Business and Summary of Significant Accounting Policies | 1. NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Business Basis of Preparation Related Party – 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. Income Taxes Financial Accounting Standards Board (“FASB”) codified within Accounting Standards Codification (“ASC”) Topic No. 740-10, Income Taxes Use of Estimates Net Loss per Share Earnings Per Share Earnings Per Share Fair Value of Financial Instruments - Fair Value Measurement – Fair Value Hierarchy The Company has categorized its financial instruments, based on the priority of inputs to the valuation technique, into a three-level fair value hierarchy. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). Financial assets and liabilities recorded on the balance sheet are categorized based on the inputs to the valuation techniques as follows: Level 1 Financial assets and liabilities for which values are based on unadjusted quoted prices for identical assets or liabilities in an active market that management has the ability to access. Level 2 Financial assets and liabilities for which values are based on quoted prices in markets that are not active or model inputs that are observable either directly or indirectly for substantially the full term of the asset or liability (commodity derivatives and interest rate swaps). Level 3 Financial assets and liabilities for which values are based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. These inputs reflect management’s own assumptions about the assumptions a market participant would use in pricing the asset or liability. When the inputs used to measure fair value fall within different levels of the hierarchy, the level within which the fair value measurement is categorized is based on the lowest level input that is significant to the fair value measurement in its entirety. The carrying amounts of cash, accrued professional fees and other accrued expenses approximate fair value because of the short-term nature of these items. Per ASC Topic 820 framework these are considered Level 3 inputs where estimates are unobservable by market participants outside of the Company and must be estimated using assumptions developed by the Company. It is not, however, practical to determine the fair value of amounts due to related party because the transactions cannot be assumed to have been consummated at arm’s length, the terms are not deemed to be market terms, there are no quoted values available for these instruments, and an independent valuation would not be practical due to the lack of data regarding similar instruments, if any, and the associated potential costs. Recent Accounting Pronouncements The Company adopted ASC Topic 842 using the modified retrospective approach and elected to utilize the Optional Transition Method. The adoption did not impact the Company’s previously reported financial statements nor did it result in a cumulative effect adjustment to retained earnings as of July 1, 2019. |

| Related Party Transactions [Abstract] | |
| Related Party Transactions | 2. RELATED PARTY TRANSACTIONS An officer of the Company charged a management fee totaling $6,000 for each of the years ended June 30, 2020 and 2019 for the use of a home office, accounting and other services. During the years ended June 30, 2020 and 2019, the officer also paid operating expense of $25 and $25, respectively, on behalf of the Company to support the Company’s operation and these payments were fully reimbursed to him. The balance due to this officer was $21,000 and $15,000 as of June 30, 2020 and 2019, respectively. The amounts due to this officer are unsecured, bearing no interest and are repayable on demand. |

| Income Taxes | 3. INCOME TAXES Income taxes for the years ended June 30, 2020 and 2019 represent state minimum franchise tax of $800. The Company had net operating loss carryovers for federal income tax purposes totaling approximately $191,106 and $160,383, as of the years ended June 30, 2020 and 2019, respectively. The ultimate realization of such loss carryovers will be dependent on the Company attaining future taxable earnings. Based on the level of historical operating results and projections of future taxable earnings, management believes that it is more likely than not that the Company will not be able to utilize the benefits of these carryovers. The effective tax rates for the years ended June 30, 2020 and 2019 were 21%. As of June 30, 2020 and 2019, the Company had full valuation allowances recorded against the deferred tax assets of $40,132 and $33,680, respectively. If not utilized, the carryovers expire beginning in fiscal 2027. The Company files income tax returns in the U.S. federal jurisdiction and in the state of California. With few exceptions, the Company is no longer subject to U.S. federal and state tax examinations by tax authorities for the years ending June 30, 2013 and earlier. According to Section 382 of the Internal Revenue Code of 1986, as amended, ownership changes may limit the amount of the NOL carry forwards that can be utilized annually to offset future taxable income and tax, respectively. |

| Commitments and Contingencies Disclosure [Abstract] | |
| Commitments and Contingencies | 4. COMMITMENTS AND CONTINGENCIES In March 2017, the Company received a letter from the County of Santa Clara, California, which claimed that the Company is delinquent on its property taxes relating to tax year 1988/1989 in the amount of $80,238.07 including penalties which should be paid immediately. The Company believes that these property taxes were related to the period prior to the filing of the reorganization of the Company under Chapter 11 of the Bankruptcy Code in the United States Bankruptcy Court for the Central District of California on November 22, 1988 and the eventual confirmation of the Company’s Amended Plan of Reorganization (the “Plan”) by the Bankruptcy Court on May 17, 1990, and thus have been settled in accordance with the terms of the Plan and are therefore invalid. The Company has informed the County of Santa Clara that if it wants to assert its claim, it would have to petition to the Bankruptcy Court for relief. The Company does not recognize the said claim and therefore has not recorded any tax liabilities related to this claim. If the County of Santa Clara claim is adjudicated to be valid and the Company is liable, the tax liabilities imposed could have a material effect on the Company’s result of operations and financial position. |
