A Japanese manga editor from Morioka City.

Since 2023, Rei has been part of the editorial team at *Weekly Shonen Champion*, a long-running manga magazine published by Akita Shoten. Currently, Rei serves as the editor for manga artist Shinobu Seguchi, known for dynamic storytelling and impactful characters. Rei’s passion for manga began early. During high school, Rei became a devoted fan of *Prisoner Riku*, a series serialized in *Weekly Shonen Champion* that left a deep impression with its emotional storytelling and powerful message of resilience and justice.

The admiration Rei had for *Prisoner Riku* as a reader later became a professional connection. As a new editor, Rei had the opportunity to work under Hideo Matsuyama, the very first editor of *Prisoner Riku*. Under his mentorship, Rei played a key role in launching the historical action manga *Hikuidori( The Fire-Eating Bird)*,a/k/a *Oedo Fire Slayer – The Legend of Phoenix*, a part of the *Ushū Borotobi-gumi* series. This experience not only gave Rei a front-row seat to the process of creating a new manga but also allowed Rei to witness firsthand how editorial guidance shapes a story’s development.
