Mutsumi Aoki is back with fresh material for fans of yuri manga. The creator's new series, Seinaru Hime no Kakushigoto (The Holy Princess' Secret Affair), will debut in the October issue of Ichijinsha's Comic Yuri Hime magazine on August 18.

The story centers on a magic-wielding princess and a serious knight as they embark on a journey toward sainthood. While details remain limited at this stage, the premise hints at a blend of fantasy adventure and character-driven storytelling.

This marks Aoki's return to manga publication following the conclusion of their previous series, Osananajimi ga Zettai ni Makenai Love Come: Otonari no Yon-shimai ga Zettai ni Honobono suru Nichijō (A Romantic Comedy Where the Childhood Friend Absolutely Will Not Lose: The Four Sisters Next Door Who Absolutely Have A Warm Everyday Life), which wrapped up in November 2022. That manga was a spinoff of Shūichi Nimaru's light novel series of the same name, focusing on the four sisters of the Shida family. The spinoff ran for nearly two years after launching in January 2021, with Kadokawa releasing the final volume in March 2023.

Aoki's work has resonated with readers interested in character-focused narratives and slice-of-life storytelling, so the shift toward a fantasy adventure with yuri elements in Seinaru Hime no Kakushigoto represents an interesting creative direction. Comic Yuri Hime, Ichijinsha's dedicated yuri magazine, provides a strong platform for reaching an established audience interested in the genre.

Manga readers can expect the series to begin serialization when the October issue hits shelves on August 18. Whether this new work will eventually receive an anime adaptation remains to be seen, but Aoki's previous projects have attracted publisher interest in bringing stories to screen.
