Reborn as Geto Suguru, I Became the Designated Snarker

An unknown shut-in transmigrates into Suguru Geto.

A clueless fan of Jujutsu Kaisen who knows a little about it, plus a meme-obsessed troll.

A thirty-year-old shut-in wizard whose mental age is childish enough to match Satoru Gojo's.

He doesn't want to swallow cursed objects and has little desire to grow stronger.

He thinks Shoko Ieiri is beautiful, but her personality isn't his cup of tea.

Theme: Even a snarky character has a future.
