In this world, I guess I'll be a demon general

Saikou Ashi is mostly hated by all of his classmates, enough that they started a rumor that he sent 15 classmates to the hospital for no reason. But when he and his classmates are transported to another world, and the one that's known as "Stat" is persuaded by the main one who started the rumor, Mori Takagiri, and given no stats, he becomes incredibly angry and leaves them all with a couple of injuries.

[You that is betrayed by thy light, where else for thy to turn to other than the darkness. Will you pledge thyself to me, Demon overlord Rein.]

With the message Saikou gets, he says why not. In this world, he's known as demon general Saikou.
