"2.5 Dimensional Seduction" (Japanese: 2.5次元の誘惑, Hepburn: Nitengo-jigen no Ririsa) is a Japanese manga series written and illustrated by Yu Hashimoto. It began serialization on Shueisha's Shōnen Jump+ website in June 2019. The story follows Masamune Okumura, a high school student and president of the manga club, who is obsessed with the fictional 2D character Liliel. His life is turned upside down when Lilysa Amano, a first-year student passionate about cosplay, joins the club. Lilysa is not only a fan of Liliel but also encourages Okumura to become her photographer. This romantic comedy explores the boundaries between 2D and 3D worlds, and the conflict Okumura experiences between his love for real life and his obsession with fictional characters. An anime adaptation produced by J.C.Staff aired from July to December 2024, with a second season announced. Additionally, an online role-playing game, "2.5 Dimensional Seduction: Angels on Stage", was released in September 2024 for iOS, Android, and PC.
