Masamune Okumura, the president and sole member of the Manga Research Club at his high school, is an unapologetic otaku devoted entirely to his 2D fictional crush, the fiery demon girl Liliel. Okumura vehemently rejects the real world and real women, swearing he has no interest in three-dimensional romance. However, his solitary otaku lifestyle is abruptly upended by the arrival of Ririsa Amano, a energetic first-year student. Ririsa bursts into the clubroom with a shocking declaration: she is also deeply in love with Liliel and desperately wants to become her in real life through cosplay.Initially resistant, Okumura is quickly won over by Ririsa’s genuine passion, infectious enthusiasm, and encyclopedic knowledge of the character. He agrees to become her official cameraman and producer, using his artistic talents and otaku eye for detail to help her bring Liliel to life. As they collaborate on photo shoots, conventions, and handcrafted costumes, Okumura is forced to confront his deep-seated prejudice against the real world. Ririsa's unwavering dedication and vulnerability begin to chip away at his emotional walls, slowly blurring the distinct boundaries he had drawn between his beloved two-dimensional fantasies and three-dimensional reality.Their creative partnership soon expands into a tight-knit circle of passionate creators and fellow cosplayers. They are joined by Mikari Tachibana, Okumura’s childhood friend who harbors secret, complicated romantic feelings for him and struggles with her own complex history with cosplay. The group also encounters Nonoa, a brilliant yet socially awkward cosplayer with a sharp tongue, and Mayura, a skilled makeup artist. Together, this eclectic ensemble navigates the high-stakes, highly competitive world of modern cosplay culture.As they prepare for increasingly difficult conventions and photoshoots, the characters face intense rivalries, artistic insecurities, and
personal growth. Ririsa pushes her physical and emotional limits to capture the exact essence of Liliel, while Okumura evolves from a reclusive fan into a fiercely protective and talented director. Along the way, the series explores the emotional toll of artistic expression and public scrutiny. Beneath the vibrant costumes and playful fanservice lies a deeply character-driven drama about self-acceptance, friendship, and the courage to embrace genuine
human connection. Ultimately, Okumura realizes that real-world relationships and shared passions can be just as magical and fulfilling as any 2D fantasy, leading him to question where his true affections actually lie.
