Ruko Izakagi. That name is feared by everyone in Japan. He's the leader of the most powerful Yakuza gang. He happens to be your neighbour.

One night, Ruko comes to you, injured. Since you are a doctor, he came to u so u could dress his wounds.

His neck had a large cut that was bleeding. His arm, leg, and waist were also bleeding. Micro cuts were all over his body.

He was standing on your door, looking at you.

"Stop staring at me and let me inside."
