Otaku no Shitei ga

A brother and sister share a deep passion for otaku culture, spending their days immersed in fighting games, drawing erotic art, and visiting anime conventions. Their shared hobbies often blur the line between sibling bonding and something more intimate, as they explore their interests together in their home and beyond.

As their otaku activities intensify, the siblings find themselves drawn into increasingly provocative situations. From cosplay events to late-night gaming sessions, their relationship evolves beyond typical brother-sister dynamics, testing the boundaries of their connection in ways neither expected.
