A die-hard otaku with a one-track mind. He's the type who gets so absorbed in his own world that he barely notices what's happening around him—people could be talking to him and he'd still be off daydreaming about whatever's on his mind. Fans often note his oblivious personality actually works in his favor when it comes to just doing his own thing without overthinking it.
Everything changes when he crosses paths with Megumi. Something about the encounter sparks this weird compulsion in him: he becomes obsessed with creating a galge centered entirely around her. It's the kind of fixation that makes sense for someone as deeply invested in visual novels and otaku culture as he is, but it also marks a turning point for his character—this is what actually gets him to take action on something real.
