Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	NOTE 5. COMMITMENTS AND CONTINGENCIES Registration Rights The holders of the Founder Shares, Private Units (including the securities contained therein) and Units (including securities) are entitled to registration rights pursuant to a registration rights agreement to be signed prior to or on the effective date of the Initial Public Offering. The holders of these securities are entitled to make unlimited demands that the Company register such securities. In addition, the holders have certain piggyback registration rights with respect to registration statements filed subsequent to the completion of the initial Business Combination. However, the registration rights agreement provides that the Company will not permit any registration statement filed under the Securities Act to become effective until termination of the applicable lock-up period, which occurs (i) in the case of the Founder Shares, and (ii) in the case of the private units and the respective Class A ordinary shares underlying such units, 30 days after the completion of the initial Business Combination. The Company will bear the expenses incurred in connection with the filing of any such registration statements. Underwriting Agreement The underwriter had a 45-day option from the date of the Initial Public Offering to purchase up to an additional 2,625,000 Units to cover over-allotments, if any. On May 16, 2025, the underwriters elected to fully exercise their over-allotment option to purchase an additional 2,625,000 Units at a price of $10.00 per Unit. The underwriter was entitled to a cash underwriting discount of $3,500,000 in the aggregate, or 2.0% of the gross proceeds of the Units offered in the Initial Public Offering, excluding any proceeds from Units sold pursuant to the underwriter’s over-allotment option. The underwriter paid the Company an aggregate amount of $2,000,000 at the closing of the Initial Public Offering as reimbursement to the Company for certain of its expenses and fees incurred in connection with the Initial Public Offering. Additionally, the underwriter was entitled to a deferred underwriting discount of 3.5% of the gross proceeds of the Initial Public Offering held in the Trust Account, other than the gross proceeds from the Units sold pursuant to the underwriter’s option to purchase additional Units, and 5.5% of the gross proceeds from the additional Units sold pursuant to such option, or $7,568,750 in the aggregate, payable upon the completion of the Company’s initial Business Combination subject to the terms of the underwriting agreement. The deferred underwriting discount will be payable to the underwriter upon the closing of the initial Business Combination in two portions: (i) $0.10 per Unit sold in the offering shall be paid to the underwriter in cash and (ii) up to $0.25 per Unit sold in the offering (other than the Units sold pursuant to the underwriter’s option to purchase additional Units, which will be up to $0.45 per Unit sold pursuant to such option), shall be paid to the underwriter in cash based on the funds remaining in the Trust Account after giving effect to public shares that are redeemed in connection with an initial Business Combination. Deferred Legal Fees As of December 31, 2025 and 2024, the Company had deferred legal fees of $920,140 and $0, respectively, to be paid to the Company’s legal advisors upon consummation of the initial Business Combination. As the settlement or liquidation of amounts of deferred legal fees are not reasonably expected to require the use of current assets or require the creation of current liabilities, the amount is classified as a non-current liability in the accompanying balance sheets as of December 31, 2025 and 2024. Risks and Uncertainties The United States and global markets are experiencing volatility and disruption following the geopolitical instability resulting from the ongoing Russia-Ukraine conflict and the Israel-Hamas conflict. In response to the ongoing Russia-Ukraine conflict, the North Atlantic Treaty Organization (“NATO”) deployed additional military forces to eastern Europe, and the United States, the United Kingdom, the European Union and other countries have announced various sanctions and restrictive actions against Russia, Belarus and related individuals and entities, including the removal of certain financial institutions from the Society for Worldwide Interbank Financial Telecommunication payment system. Certain countries, including the United States, have also provided and may continue to provide military aid or other assistance to Ukraine and to Israel, increasing geopolitical tensions among a number of nations. The invasion of Ukraine by Russia and the Israel-Hamas conflict and the resulting measures that have been taken, and could be taken in the future, by NATO, the United States, the United Kingdom, the European Union, Israel and its neighboring states and other countries have created global security concerns that could have a lasting impact on regional and global economies. Although the length and impact of the ongoing conflicts are highly unpredictable, they could lead to market disruptions, including significant volatility in commodity prices, credit and capital markets, as well as supply chain interruptions and increased cyberattacks against U.S. companies. Additionally, any resulting sanctions could adversely affect the global economy and financial markets and lead to instability and lack of liquidity in capital markets. Any of the above mentioned factors, or any other negative impact on the global economy, capital markets or other geopolitical conditions resulting from the Russian invasion of Ukraine, the Israel-Hamas conflict and subsequent sanctions or related actions, could adversely affect the Company’s search for an initial Business Combination and any target business with which the Company may ultimately consummate an initial Business Combination.
