The Regressors are Trying to Kill Me - Chapter 2

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!

After living in a desolate land, where there wasn’t even a single blade of grass and hunger was an everyday reality, Min Sung finally returns to Earth: his home.

This thought had grown deep in William’s mind!
