I Have the Alchemy Emperor in My Head - Chapter 9

A protagonist reborn in another world.

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!

She is the rising (new) movie queen of the entertainment circle, who is also Beijing’s Ye Family long-lost Second Young Miss. Everyone knows that the Ye Family Eldest Young Miss is the chairman of Fenghai Group; Ye Family Third Young Master is a Major General of the military area; and yet, Ye family wants the second young miss to come back home, but she is just a flower vase (pretty face) of the entertainment industry.
