Always a Catch!

Lore & Background

The story follows Maria Annovazzi, the fifth daughter of the Duke Annovazzi of the Kingdom of Muro. Raised as the heir to her family's dukedom, she mastered the family's traditional martial arts style of 80 forms. After her younger brother was born, she lost her title as heir and traveled to the neighboring Kingdom of Rubini to find a marriage partner. There, Crown Prince Renato di Rubini mistakenly informed Maria of the annulment of his engagement to her cousin Aida Ametis, and eventually fell in love with Maria, proposing to her. She became his fiancée and later received formal training to become crown princess, though her free-spirited personality and tendency to resolve problems through martial arts remained unchanged.

Reader's Guide

Always a Catch! is significant as a light novel series that transitioned from a user-generated web story to a multi-media franchise including a manga and an anime adaptation. Its premise—a martial-arts-trained noblewoman navigating royal politics—offers a comedic and action-oriented twist on the typical isekai or romance genre. The series achieved over 1 million copies in circulation by November 2025, indicating strong commercial success. The anime adaptation, produced by TMS Entertainment and animated by Troyca, aired in 2026 and was streamed by Crunchyroll, expanding its international reach. The series' English-language manga publication by Square Enix Manga & Books further broadened its audience. Its legacy lies in demonstrating how web-published stories can gain mainstream publishing and anime adaptation, particularly within the Japanese light novel industry.

From Web Novel to Global Franchise

The story of Always a Catch! traces a remarkably rapid trajectory from online serialization to multi-format media presence. Mayo Momoyo first posted the work as a short story on the user-generated platform Shōsetsuka ni Narō in late October 2020, and a follow-up serialization kicked off just over a month later in early December. The project caught the eye of Square Enix, which brought the series under its SQEX Novel imprint with artwork by Itsuki Mito beginning in August 2021. By April 2026, seven light-novel volumes had reached readers. The franchise expanded further when Kaki Nagato launched a manga adaptation on Square Enix's Manga Up! service in spring 2022, eventually collecting eleven tankōbon volumes by mid-2026. English-language fans gained access through Square Enix Manga & Books, whose first volume shipped in November 2024, and the series also streams on Manga Up! Global. The anime adaptation, announced in November 2025, brought the story to animated screens for a spring 2026 broadcast run, cementing the title's status as a full-fledged cross-media property.

A Martial-Arts Heir Meets the Royal Court

At the heart of the series is Maria Annovazzi, the fifth daughter of the Duke Annovazzi in the Kingdom of Muro. Because no younger sibling had yet been born, Maria was groomed as the dukedom's heir and trained to mastery in the family's traditional martial-arts style, which comprises eighty distinct forms. When a younger brother arrives, she loses that inheritance and sets out for the neighboring Kingdom of Rubini with the practical goal of securing a marriage partner. What she finds instead is the crown prince, Renato di Rubini, who—after a case of mistaken identity involving his originally arranged fiancée Aida—accidentally extends an engagement to Maria. The royal couple take a liking to her and enroll her in formal crown-princess instruction, including etiquette lessons. Yet Maria's free-spirited disposition and her instinct to settle disputes with a well-placed punch remain stubbornly intact, creating a persistent friction between courtly expectation and her warrior's nature.

A Court Full of Complicated Relationships

The supporting cast of Always a Catch! weaves a dense web of familial and political ties. Renato's younger brother Placido, the second prince, ultimately becomes engaged to Aida Ametis—the very woman originally slated for Renato—and holds his wedding before his brother does. Aida herself, a polished noblewoman from the Ametis ducal house, remains on cordial terms with Maria even after the broken engagement, though she does not hesitate to deliver a stern reprimand when Maria recklessly charges into a burning building to rescue strangers. Renato's circle includes Raimondo Cigata, a marquis's son and gifted bureaucrat who is perpetually swept into Maria's chaos, and his cousin Ireneo Marchei, a man in his early thirties who still flirts with every woman in the room. Gabriele Morand, Renato's foster brother and former royal-guard member, initially bristles at learning his prince's fiancée has changed but gradually becomes Maria's sparring partner and friend.

Reception and the Anime Adaptation

By November 2025, Always a Catch! had surpassed one million copies in circulation, a milestone that underscored its strong reader base before the anime even premiered. The series found an international audience through Square Enix's English-language publishing arm, with the first translated volume arriving in November 2024, and through the Manga Up! Global platform for the manga. The anime adaptation, announced on November 3, 2025, was produced by TMS Entertainment with animation handled by Troyca. Akira Oguro directed, Michiko Yokote wrote the series composition, Isamu Suzuki designed the characters, and composers Kana Hashiguchi and Natsuki Hamada crafted the score. The opening theme, "Chikai wa Kyun to," is performed by HoneyWorks and Airi Suzuki, while Yoshino sings the ending, "Dead or Love." The series aired from April 2 to June 18, 2026 on Tokyo MX and partner networks, with Crunchyroll handling streaming and Muse Communication distributing the license across South and Southeast Asia.
