Summary of Significant Accounting Policies [Abstract]
Basis of Presentation	*Basis of Presentation* The accompanying unaudited condensed financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and Article 8 of Regulation S-X of the SEC. Certain information or footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted, pursuant to the rules and regulations of the SEC for interim financial reporting. Accordingly, they do not include all the information and footnotes necessary for a complete presentation of financial position, results of operations, or cash flows. In the opinion of management, the accompanying unaudited condensed financial statements include all adjustments, consisting of a normal recurring nature, which are necessary for a fair presentation of the financial position, operating results and cash flows for the periods presented. The accompanying unaudited condensed financial statements should be read in conjunction with the Company’s prospectus for its Initial Public Offering as filed with the SEC on April 25, 2025, as well as the Company’s Current Report on Form 8-K, as filed with the SEC on May 5, 2025. The interim results for the period from January 31, 2025 through March 31, 2025, are not necessarily indicative of the results to be expected for the year ending December 31, 2025 or for any future periods.
Emerging Growth Company	*Emerging Growth Company* The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.
Use of Estimates	*Use of Estimates* The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the unaudited condensed financial statements and the reported amounts of expenses during the reporting period. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the unaudited condensed financial statement, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates.
Cash and Cash Equivalents	*Cash and Cash Equivalents* The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company did not have any cash or cash equivalents as of March 31, 2025 and December 31, 2024.
Concentration of Credit Risk	*Concentration of Credit Risk* Financial instruments that potentially subject the Company to concentrations of credit risk consist of a cash account in a financial institution, which, at times, may exceed the Federal Deposit Insurance Corporation coverage limit of $250,000. Any loss incurred or a lack of access to such funds could have a significant adverse impact on the Company’s financial condition, results of operations, and cash flows.
Deferred Offering Costs	*Deferred Offering Costs* The Company complies with the requirements of the ASC 340-10-S99 and SEC Staff Accounting Bulletin Topic 5A, “Expenses of Offering”. Deferred offering costs consist of underwriting, legal, accounting and other expenses incurred through the condensed balance sheet date that were directly related to the Initial Public Offering. FASB ASC 470-20, “Debt with Conversion and Other Options,” addresses the allocation of proceeds from the issuance of convertible debt into its equity and debt components. The Company applies this guidance to allocate Initial Public Offering proceeds from the Units between Class A ordinary shares and Public Rights, using the residual method by allocating Initial Public Offering proceeds first to the assigned value of the Public Rights and then to the Class A ordinary shares. Offering costs allocated to the Public Shares will be charged to temporary equity, and offering costs allocated to Public Rights and Private Placement Rights (defined in Note 4) will be charged to shareholder’s deficit, as the Rights, after management’s evaluation, will be accounted for under equity treatment. Had the Initial Public Offering proved to be unsuccessful, these deferred costs, as well as additional expenses incurred, would have been charged to operations.
Net Loss Per Ordinary Share	*Net Loss Per Ordinary Share* Net loss per ordinary share is computed by dividing net loss by the weighted average number of ordinary shares outstanding during the period, excluding ordinary shares subject to forfeiture. Weighted average shares were reduced for the effect of an aggregate of 1,100,000 ordinary shares that are subject to forfeiture if the over-allotment option is not exercised by the underwriter (see Note 6). At March 31, 2025 and December 31, 2024, the Company did not have any dilutive securities and other contracts that could, potentially, be exercised or converted into ordinary shares and then share in the earnings of the Company. As a result, diluted net loss per ordinary share is the same as basic net loss per ordinary share for the period presented.
Income Taxes	*Income Taxes* The Company accounts for income taxes under ASC 740, “Income Taxes” (“ASC 740”), which prescribes a recognition threshold and measurement process for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more-likely-than-not to be sustained upon examination by taxing authorities. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. There were no unrecognized tax benefits and no amounts accrued for interest and penalties as of March 31, 2025 and December 31, 2024. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since inception. There is currently no taxation imposed on income by the Government of the Cayman Islands. In accordance with Cayman income tax regulations, income taxes are not levied on the Company. Consequently, income taxes are not reflected in the Company’s financial statement. The Company’s management does not expect that the total amount of unrecognized tax benefits will materially change over the next twelve months.
Derivative Financial Instruments	*Derivative Financial Instruments* The Company evaluates its financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives in accordance with ASC Topic 815, “Derivatives and Hedging”. For derivative financial instruments that are accounted for as liabilities, the derivative instrument is initially recorded at its fair value on the grant date and is then re-valued at each reporting date, with changes in the fair value reported in the unaudited condensed statement of operations. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is evaluated at the end of each reporting period. Derivative liabilities are classified in the unaudited condensed balance sheets as current or non-current based on whether or not net cash settlement or conversion of the instrument could be required within 12 months of the condensed balance sheet date. The underwriter’s over-allotment option is deemed to be a freestanding financial instrument indexed on the contingently redeemable shares and will be accounted for as a liability pursuant to ASC 480 if not fully exercised at the time of the Initial Public Offering. On April 28, 2025, the Company consummated the Initial Public Offering including the full exercise of the underwriter’s over-allotment option.
Fair Value of Financial Instruments	*Fair Value of Financial Instruments* The fair value of the Company’s assets and liabilities, which qualify as financial instruments under ASC Topic 820, “Fair Value Measurements and Disclosures,” approximates the carrying amounts represented in the accompanying balance sheet, primarily due to their short-term nature.
Share Rights	*Share Rights* The Company accounted for the Public and Private Placement Rights issued in connection with the Initial Public Offering and the private placement in accordance with the guidance contained in FASB ASC Topic 815, “Derivatives and Hedging”. Accordingly, the Company evaluated and classified the rights under equity treatment at their assigned value.
Share-based compensation	*Share-based compensation* The Company records share-based compensation in accordance with FASB ASC Topic 718, “Compensation-Share Compensation” (“ASC 718”), guidance to account for its share-based compensation. It defines a fair value-based method of accounting for an employee share option or similar equity instrument. The Company recognizes all forms of share-based payments at their fair value on the grant date, which are based on the estimated number of awards that are ultimately expected to vest. Share-based payments are valued using a Probability Weighted Expected Return Method (“PWERM Model”). Grants of share-based payment awards issued to non-employees for services rendered have been recorded at the fair value of the share-based payment, which is the more readily determinable value. The grants are amortized on a straight-line basis over the requisite service periods, which is generally the vesting period. If an award is granted, but vesting does not occur, any previously recognized compensation cost is reversed in the period related to the termination of service. Share-based compensation expenses will be included in costs and operating expenses depending on the nature of the services provided in the statement of operations.
Recently Issued Accounting Standards	*Recently Issued Accounting Standards* In November 2024, the FASB issued Accounting Standards Update (“ASU”) 2024-03, “Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses”, requiring public entities to disclose additional information about specific expense categories in the notes to the financial statements on an interim and annual basis. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, and for interim periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact of adopting ASU 2024-03. Management does not believe that any other recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on the Company’s financial statement.
