MTL - Doomsday: I Have One More Keyword Than Others - Chapter 75 Game in the game (Congratulations to the leader Zebra 9353)

Kusumi Chiharu gets a message one day that he has been selected as a Monster Tamer, and he is prompted to select his first partner. He thinks little of the message until he receives a giant package the following day. He assumes it’s the porn books he ordered, but the huge box ends up containing the unconscious body of a near-naked girl! She’s a ghoul named Zonmi, who intends to fight beside him as his partner.

However, it turns out that other hot girls at his mostly-male high school are also magical entities, and Zonmi may not be the only one who wants to fight by his side!

He became a teacher at the best magic academy in the empire.
….For being mistaken for someone else.
