In a small town in southern Japan, crime and delinquency are one of the main factors that affects 40% of the country's population.Several cases of murder have been recorded in recent years. At the heart of this story, an 18-year-old , Kotaro lived with his father in a small part of town and worked as a baker to support to their needs. He often came home very late at night. He didn't have the means of financing these studies, Kotaro dreamed of becoming a detective.

"I'm back father" Kotaro said enthusiastically.

And received no response from his father, something quite bizarre.

"It's quite strange, he should be there waiting for me as always".

So Kotaro was walking towards his father's room and there was no one there, Kotaro started worrying about the situation until he decided to go to the bathroom, horrified by what he was saw, he finds his father lying on the ground in a bloodbath disturbed by this horror scene, Kotaro screams with all his might.

"Noooo I don't believe it dad, Noooo my god who could do such a thing".

"Why is this life unfair, my father did nothing wrong to deserve this".

After letting out all that screaming, Kotaro hears the sound of green breaking in one of the rooms in the house. His father's killer was trying to escape through the window, but Kotaro couldn't see his face because the man was wearing a hood. But what Kotaro noticed about the killer was that he had a tattoo in skull shape on his neck.

Kotaro then calls the police and rescuers. He then found himself alone with no family, his father was the only person he had left. he felt a terrible hatred towards his father's murderer.

The long tomorrow kotaro goes to the police station to describe the identity of the criminal, and it turns out that this criminal was one of the members of the gang of the headless, one of the major criminal organizations existing within the country . Their leader Mizu, is a follower of occult practice and one of the most wanted criminals in the country. But the police were never able to incarcerate this criminal, many described him as a superhuman linked to these superhuman abilities.

"I miss you dad, my life no longer has any meaning" in a sad voice. Kotaro was about to snap, when suddenly a strange voice said his name.
