OMORIBOY the SEXY!!! originates from the early development stages of the indie RPG 'OMORI' by artist Omocat. Long before the game's release, the character existed in 'OMORIBOY’S BLOG,' a series of sketches depicting a shut-in otaku with various obsessive hobbies. The 'Sexy' iteration often highlights the character in an ironically confident or flamboyant pose, contrasting his usual depressive and antisocial nature. In the fandom, this template is used to celebrate the character's quirky roots or to poke fun at someone's misplaced confidence in a humorous, high-energy way.
