Miluna Acquisition Corp

12F, No. 43,

Cheng Gong Road, Sec 4, Neihu

Taipei, Taiwan

Re: <u>Registration Statement of Miluna Acquisition Corp</u>

Ladies and Gentlemen:

We have acted as counsel to Miluna Acquisition Corp, a Cayman Islands exempted company (the "**Company**"), in connection with the Registration Statement on Form S-1 (the "**Registration Statement**") filed by the Company with the U.S. Securities and Exchange Commission (the "**Commission**") under the Securities Act of 1933, as amended (the "**Act**"), of the offer and sale of up to 6,900,000 units of the Company, including the underwriters' over-allotment option (collectively, the "**Units**"), each consisting of one ordinary share, par value $0.0001 per share (each, an "**Ordinary Share**" and collectively, the "**Ordinary Shares**") and one warrant, each warrant representing the right to purchase one Ordinary Share (each, a "**Warrant**" and collectively, the "**Warrants**"), to be issued and sold pursuant by the Company, of which 900,000 Units are issuable upon exercise of an option to purchase additional Units granted to the underwriter.

This opinion letter is rendered in accordance with the requirements of Item 601(b)(5) of Regulation S–K under the Act, and no opinion is expressed herein as to any matter pertaining to the contents of the Registration Statement or related prospectus, any prospectus filed pursuant to Rule 424(b) with respect thereto, other than as expressly stated herein with respect to the issue of the Units and the Warrants.

In connection with our opinion expressed below, we have examined originals or copies certified or otherwise identified to our satisfaction of the following documents and such other documents, corporate records, certificates and other statements of government officials and corporate officers of the Company as we deemed necessary for the purposes of the opinion set forth in this opinion letter:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) the form of the underwriting agreement proposed to be entered into between the Company and the underwriters named therein that is filed as *Exhibit 1.1* to the Registration Statement (the "**Underwriting Agreement**");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) the specimen unit certificate that is filed as *Exhibit 4.1* to the Registration Statement (the "**Specimen Unit Certificate**");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) the specimen warrant certificate that is filed as *Exhibit 4.3* to the Registration Statement (the "**Specimen Warrant Certificate**"); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) the form of the warrant agreement proposed to be entered into between the Company and Lucky Lucko, Inc. d/b/a Efficiency, as warrant agent that is filed as *Exhibit 4.4* to the Registration Statement (the "**Warrant Agreement**," and together with the Underwriting Agreement, the Specimen Unit Certificate, and the Specimen Warrant Certificate, the "**Transaction Documents**").

With your consent, we have relied upon certificates and other assurances of officers of the Company and others as to factual matters without having independently verified such factual matters. We are only opining herein as to the internal laws of the State of New York, and we express no opinion with respect to the applicability thereto, or the effect thereon, of the laws of any other jurisdiction, domestic or foreign, or as to any matters of municipal law or the laws of any local agencies within any state. Various matters concerning the laws of the Cayman Islands with respect to the Units, Warrants and Shares are addressed in the opinion of Harney Westwood & Riegels, which has been separately provided to you. We express no opinion with respect to those matters herein, and, to the extent such matters are necessary to the conclusions expressed herein, we have, with your consent, assumed such matters.

![](ex5-1_001.jpg)

Subject to the foregoing and the other matters set forth herein, it is our opinion that, as of the date hereof:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. When
 the Registration Statement becomes effective under the Act and the Units have been issued
 and delivered by the Company pursuant to the Underwriting Agreement against the payment of
 the consideration set forth in the Underwriting Agreement, the Units will constitute valid
 and binding obligations of the Company, enforceable against the Company in accordance with
 their terms.

2. When
 the Registration Statement becomes effective under the Act and the Warrants included in the
 Units have been delivered by the Company pursuant to the Underwriting Agreement against the
 payment of the consideration set forth in the Underwriting Agreement, the Warrants will constitute
 valid and binding obligations of the Company, enforceable against the Company in accordance
 with their terms.

Our opinions set forth in numbered paragraphs 1 and 2 are subject to: (i) the effect of bankruptcy, insolvency, reorganization, fraudulent transfer, moratorium or other similar laws relating to or affecting the rights and remedies of creditors; (ii) the effect of general principles of equity, whether considered in a proceeding in equity or at law (including the possible unavailability of specific performance or injunctive relief), concepts of materiality, reasonableness, good faith and fair dealing, and the discretion of the court before which a proceeding is brought; (iii) the invalidity under certain circumstances under law or court decisions of provisions providing for the indemnification of or contribution to a party with respect to a liability where such indemnification or contribution is contrary to public policy; and (iv) we express no opinion as to (a) any provision for liquidated damages, monetary penalties or other economic remedies to the extent such provisions are deemed to constitute a penalty, (b) consents to, or restrictions upon, governing law, jurisdiction, venue, arbitration, remedies, or judicial relief, (c) waivers of rights or defenses, (d) any provision requiring the payment of attorneys' fees, where such payment is contrary to law or public policy, (e) advance waivers of claims, defenses, rights granted by law, or notice, opportunity for hearing, evidentiary requirements, statutes of limitation, trial by jury or at law, or other procedural rights, (f) waivers of broadly or vaguely stated rights, (g) provisions for exclusivity, election or cumulation of rights or remedies, (h) provisions authorizing or validating conclusive or discretionary determinations, (i) proxies, powers and trusts, (j) provisions prohibiting, restricting, or requiring consent to assignment or transfer of any right or property, (k) any provision to the extent it requires that a claim with respect to a security denominated in other than U.S. dollars (or a judgment in respect of such a claim) be converted into U.S. dollars at a rate of exchange at a particular date, to the extent applicable law otherwise provides, and (l) the severability, if invalid, of provisions to the foregoing effect.

With your consent, we have assumed:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) the issuance of Warrants and Units have been or will be duly authorized by the Company and the Transaction Documents have been or will be duly authorized, executed and delivered by the Company and the other parties thereto;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) the Company (i) is duly incorporated and is validly existing and in good standing, (ii) has requisite legal status and legal capacity under the laws of the jurisdiction of its organization and (iii) has complied and will comply with all aspects of the laws of the jurisdiction of its organization in connection with the transactions contemplated by, and the performance of its obligations under, the Transaction Documents;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) each of the Transaction Documents constitutes or will constitute a legally valid and binding obligations of the parties thereto other than the Company, enforceable against each of them in accordance with their respective terms;

![](ex5-1_001.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) neither (a) the execution and delivery by the Company of the Transaction Documents nor the performance by the Company of its obligations thereunder or (b) the issuance and sale of the Units or Warrants: (i) conflicts or will conflict with then-effective memorandum and articles of association of the Company, (ii) constitutes or will constitute a violation of, or a default under, any lease, indenture, instrument or other agreement to which the Company or its property is subject, (iii) contravenes or will contravene any order or decree of any governmental authority to which the Company or its property is subject, or (iv) violates or will violate any law, rule or regulation to which the Company or its property is subject (except that we do not make the assumption set forth in this clause (iv) with respect to the laws of the State of New York); and (e) that the status of the Warrants or Units as legally valid and binding obligations of the parties will not be affected by any (i) breaches of, or defaults under, agreements or instruments, (ii) violations of statutes, rules, regulations or court or governmental orders, or (iii) failures to obtain required consents, approvals or authorizations from, or to make required registrations, declarations or filings with, governmental authorities.

This opinion letter is for your benefit in connection with the Registration Statement and may be relied upon by you and by persons entitled to rely upon it pursuant to the applicable provisions of the Act. This opinion letter is provided solely in connection with the distribution of the Units pursuant to the Registration Statement and is not to be relied upon for any other purpose.

The opinion expressed above is as of the date hereof only, and we express no opinion as to, and assume no responsibility for, the effect of any fact or circumstance occurring, or of which we learn, subsequent to the date of this opinion letter, including, without limitation, legislative and other changes in the law or changes in circumstances affecting any party. We assume no responsibility to update this opinion letter for, or to advise you of, any such facts or circumstances of which we become aware, regardless of whether or not they affect the opinions expressed in this opinion letter.

We hereby consent to the filing of this opinion letter as *Exhibit 5.1* to the Registration Statement and to the reference to our firm as counsel for the Company that has passed on the validity of the Units and Warrants appearing under the caption "Legal Matters" in the prospectus forming part of the Registration Statement or any prospectus filed pursuant to Rule 424(b) with respect thereto. In giving this consent, we do not thereby admit that we are within the category of persons whose consent is required under Section 7 of the Act or the rules and regulations of the Commission thereunder.

Dear Sir or Madam

**Miluna Acquisition Corp, Company Number 422740 (the *Company*)**

We are lawyers qualified to practise in the Cayman Islands and have acted as Cayman Islands legal adviser to the Company in connection with the Company's registration statement on Form S-1, including all amendments or supplements thereto, filed with the United States Securities and Exchange Commission (the ***Commission***) on 2 September 2025 (the ***Registration Statement***) under the United States Securities Act of 1933, as amended (the ***Securities Act***), relating to the offering under the Registration Statement, including a related prospectus included in the Registration Statement, providing, in part, for the registration of up to 6,900,000 units of the Company consisting of (i) 6,900,000 ordinary shares of a par value of US$0.0001 each of the Company (the ***Ordinary Shares*** and such Ordinary Shares to be offered, the ***Offering Shares***) and (ii) 6,900,000 warrants of the Company and 6,900,000 Ordinary Shares issuable pursuant to the exercise of such warrants (the ***Warrant Shares***, and together with the ***Offering Shares***, collectively the ***Shares***).

We are furnishing this opinion as Exhibit 5.2 to the Registration Statement.

For the purposes of giving this opinion, we have examined the Documents (as defined in Schedule 1). We have not examined any other documents, official or corporate records or external or internal registers and have not undertaken or been instructed to undertake any further enquiry or due diligence in relation to the transaction which is the subject of this opinion.

In giving this opinion we have relied upon the assumptions set out in Schedule 2 which we have not independently verified.

Based solely upon the foregoing examinations and assumptions and upon such searches as we have conducted and having regard to legal considerations which we deem relevant, and subject to the qualifications set out in Schedule 3, we are of the opinion that under the laws of the Cayman Islands:

---

| 2.0 | **Authorised Share Capital.** Based on our review of the Restated M&A (as defined in Schedule 1), the authorised share capital of the Company, with effect from the date that the Restated M&A becomes effective, will be US$55,500 divided into 555,000,000 shares of par value of US$0.0001 each, comprising (i) 550,000,000 ordinary shares of a par value of US$0.0001 each, and (ii) 5,000,000 preferred shares of a par value of US$0.0001 each. |

| 4.0 | **Cayman Islands Law.** The statements under the headings "Taxation – Cayman Islands Tax Considerations", "Description of Securities", "Enforceability of Civil Liabilities" and "Legal Matters" in the prospectus forming part of the Registration Statement, to the extent that they constitute statements of Cayman Islands law, are accurate in all material respects as at the date of this opinion and such statements constitute our opinion. |

---

This opinion is confined to the matters expressly opined on herein and given on the basis of the laws of the Cayman Islands as they are in force and applied by the Cayman Islands courts at the date of this opinion. We have made no investigation of, and express no opinion on, the laws of any other jurisdiction. Except as specifically stated herein, we express no opinion as to matters of fact. Except as specifically stated herein, we make no comment with respect to any representations and warranties which may be made by or with respect to the Company in the Registration Statement. We express no opinion with respect to the commercial terms of the transactions the subject of this opinion.

In connection with the above opinion, we hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the reference made to our firm in the Registration Statement under the headings "Taxation – Cayman Islands Tax Considerations", "Description of Securities", "Enforceability of Civil Liabilities" and "Legal Matters" and elsewhere in the prospectus included in the Registration Statement. In giving such consent, we do not thereby admit that we come within the category of persons whose consent is required under Section 7 of the Securities Act or the Rules and Regulations of the Commission thereunder.

This opinion is limited to the matters referred to herein and shall not be construed as extending to any other matter or document not referred to herein.

This opinion shall be construed in accordance with the laws of the Cayman Islands.

(items 1 to 7 above collectively referred to as the ***Corporate Documents*** and items 1 to 8 above collectively referred to as the ***Documents***)

**Schedule 2**

Assumptions

---

| | |
|:---|:---|
| 1 | **Authenticity of Documents.** Copy documents or drafts of documents provided to us are true and complete copies of, or in the final forms of, the originals. All original Corporate Documents are authentic, all signatures, initials and seals are genuine. |
| 2 | **Corporate Documents.** All matters required by law to be recorded in the Corporate Documents are so recorded, and all corporate minutes, resolutions, certificates, documents and records which we have reviewed are accurate and complete, and all facts expressed in or implied thereby are accurate and complete as at the date of the passing of the Resolutions. |
| 3 | **Constitutional Documents.** The Restated M&A is the latest memorandum and articles of association of the Company in effect as of the time of the opinion. |
| 4 | **Resolutions.** The Resolutions have been duly executed (and whereby a corporate entity such execution has been duly authorised if so required) by or on behalf of the directors, or by or on behalf of each shareholder in respect of the shareholder resolutions, and the signatures and initials thereon are those of a person or persons in whose name the Resolutions have been expressed to be signed. The Resolutions remain in full force and effect. |
| 5 | **No Steps to Wind-up.** The directors and shareholders of the Company have not taken any steps to have the Company struck off or placed in liquidation, no steps have been taken to wind up the Company and no receiver has been appointed over any of the property or assets of the Company. |
| 6 | **Unseen Documents.** Save for the Documents provided to us there are no resolutions, agreements, documents or arrangements which materially affect, amend or vary the transactions envisaged in the Documents and, in particular, that the entry into and performance of the transactions contemplated under the Registration Statement will not cause any of the parties thereto to be in breach of any agreement or undertaking. |

---

**Schedule 3**

Qualifications

---

| | |
|:---|:---|
| 1 | **Foreign Statutes.** We express no opinion in relation to provisions making reference to foreign statutes in the Registration Statement. |
| 2 | **Commercial Terms.** Except as specifically stated herein, we make no comment with respect to any representations and warranties which may be made by or with respect to the Company in any of the documents or instruments cited in this opinion or otherwise with respect to the commercial terms of the transactions the subject of this opinion. |
| 3 | **Register of members.** Under the Companies Act, the register of members of a Cayman Islands company is by statute regarded as prima facie evidence of any matters which the Companies Act directs or authorises to be inserted therein. A third party interest in the shares in question would not appear. An entry in the register of members may yield to a court order for rectification (for example, in the event of fraud or manifest error). |
| 4 | **Meaning of Non-Assessable.** In this opinion the phrase non-assessable means, with respect to the issuance of Shares, that a shareholder shall not, in respect of the relevant Shares, have any obligation to make further contributions to the Company's assets (except in exceptional circumstances, such as involving fraud, the establishment of an agency relationship or an illegal or improper purpose or other circumstances in which a court may be prepared to pierce or lift the corporate veil). |
| 5 | **Good Standing.** The Company shall be deemed to be in good standing at any time if all fees (including annual filing fees) and penalties under the Companies Act have been paid and the Registrar of Companies has no knowledge that the Company is in default under the Companies Act (Revised) of the Cayman Islands. |
| 6 | **Economic Substance.** We have undertaken no enquiry and express no view as to the compliance of the Company with the International Tax Co-operation (Economic Substance) Act (Revised). |
