My New School Life in Another World

I was reborn in a world where Fantasy and Modern world coexisted. There are various races in that world, including Humans, Elves, Dwarves, Beastman, and Demons.

Monsters existed in this world, and they caused so much chaos that all races other than the demon race formed an organization called the Ranker Association to deal with monsters that threatened the world's peace.

And when I was 15, I enrolled in the Ranker Academy.

I can only hope, that i will have a peaceful school life.
