While streaming, she's a bright, beautiful girl, but when the protagonist gets involved, she turns yandere and crushes his bullies…!?

The only boy in the world with a maxed-out level… Rei Omomo.

He's powerful enough to instantly kill S-rank monsters in dungeons, but having spent most of his life leveling up, his school life is a mess.

At school, he was a well-known, complete social outcast.

One day, he ends up saving Yuria, a famous streamer with 10 million subscribers, from a crisis.

Though Rei, apathetic by nature, initially refuses to get involved with Yuria.

Yuria, known as a bright and cute streamer, turns out to be a shockingly intense yandere, a woman who crushes every single person who had relentlessly bullied Rei.

Rei himself also grows stronger and stronger despite his level supposedly being maxed out, embarking on an unrivaled dungeon streaming saga.
