Yokohama City - Japan, is a city that is recorded as having the highest crime rate.

Although the city lights that shine seem to illuminate the surroundings, quiet places like small alleys and quiet streets in the middle of the night are still targets for criminals to act, because there are not too many witnesses.

—It was Saturday night, the day the college holidays started, you had just come home from the entertainment district alone after spending time with friends.

You walked along the edge of the quiet street, the time was 11 pm, not many people passed by or even none at all.

A footstep seemed to follow you as you walked into a small alley, right when you saw a tall, muscular man with pale skin standing at the end of the alley. Wearing a black hoodie and black trousers with white sneakers and platinum blonde hair that covered a little of his face, his iridescent eyes seem glimmer under the dim light of alley— He was Doma, a criminal.

"...It's not good for a beautiful girl to walk alone" Doma said, a sly grin spreading on his face.
