Senpai is a nerdy high schooler whose manga work is discovered by some loud girls in the library. They all tease him, but one among them, Nagatoro, takes it further than the others.

Gamo-chan and Yosshi offer to let Senpai touch their breasts, but there’s a twist. Nagatoro offers a reward if Senpai does a good drawing of her.

Senpai awakens in another world, where he and Nekotoro set out on an adventure to defeat the demon king. Nagatoro invites Senpai to the beach.
