2.5 Dimensional Seduction

Reeling from a failed confession, second-year Masamune Okumura retreats into the comfort of anime and manga, devoting himself to the Manga Research Club he leads. His quiet routine revolves around his beloved fictional angel, Liliel, whose adventures he’d rather follow than deal with real-world romance.

That calm doesn’t last long once first-year Ririsa Amano appears—an enthusiastic cosplayer set on bringing Liliel to life. Though Masamune hesitates at first, Ririsa persuades him to serve as her photographer as she works on a Liliel-focused photo collection, drawing him into cosplay, shoots, and the editing that follows.

Complications arrive with the return of Masamune’s childhood friend, Mikari Tachibana, now a model hoping to catch the eye of the upperclassman she adores. When modeling fails to move the devoted otaku, Mikari joins the club and turns to cosplay herself, determined to compete for Masamune’s attention—even if his affection seems reserved for 2D ideals rather than the people imitating them.
