After a disastrous love confession, Masamune Okumura retreated into the loving arms of his 2D waifu Liliel. Now in his second year of high school and the sole remaining member of the Manga Research Club, he devotes his days to Liliel fandom despite her rapidly fading character popularity.
One normal day, Masamune’s solitary club life is turned upside down when a first year student named Ririsa Amano decides she wants to join the manga club. Hoping that his sexy Liliel figures and doujinshi will scare her off, he discovers that she is not just a passionate Liliel fan herself – but a Liliel cosplayer.
Masamune is eventually recruited to take photos of Ririsa’s Liliel cosplay and finds himself drawn deep into the world of cosplay and 3D love.
Not as educational about cosplay as cosplayers want, not as sexy as ecchi fans want, but at least the passion for the hobby comes through just the right amount. If you are looking for more anime recommendations like 2.5D Seduction, head on down below.
