Infinity Chocolate Demi Servant!

Yukki Kajou has always been a lonesome existence.

Or no. Not really. He's just introverted and likes to make everything dramatic. He's a simple boy, he's good to his parents, a classic honour student, he would get a job as a surgeon and earn enough money to live his life in peace with his wife.

That's how his life was supposed to be. He would forever be ignorant of the supernatural side of the world despite his neighbours, the Hyoudous. Being a literal icon of it.

But, one bored troll decided to do something quite unusual. Normally, he would mess with Issei Hyoudou and do all sorts of things with him. But, coincidentally, this time. His eyes landed on a boy who watched from the windows. A boy who looked bored and longed for something else.

Thus, Zelretch did the only thing he loved doing.

Making fate.

A Class-Card, an unusual one at that fell from the sky.

In it, the image of some sort of man-beast who wielded a huge weapon was engraved.

From that day on Yukki Kajou started changing.
