Yū Hashimoto is a Japanese manga creator, best known as the author and illustrator of the series 2.5 Dimensional Seduction. Hashimoto began serializing this work on June 15, 2019, on Shueisha’s Shōnen Jump+ website, where it continued publication for several years. The series is published in collected tankōbon volumes under Shueisha’s Jump Comics+ imprint, and an English-language version has been released by Seven Seas Entertainment under its Ghost Ship imprint. As a creator, Hashimoto’s most significant adaptation history stems directly from this series, which was developed into an anime television series produced by the studio J.C.Staff; the anime adaptation premiered in July 2024 and concluded its first season in December of the same year, with a second season announced. The narrative of 2.5 Dimensional Seduction blends romantic comedy with otaku culture and cosplay, focusing on the dynamic between a high school manga club president who claims to prefer two-dimensional fictional characters and a cosplaying girl who brings his favorite character into the real world. In terms of industry recognition, the series achieved commercial and critical success, ranking in the 2020 Next Manga Award in the web manga category, and notable endorsements include a recommendation from Eiichiro Oda, the creator of One Piece. Beyond the manga and its anime adaptation, the property expanded into a video game, further establishing Hashimoto’s original work as a multi-platform property.
