Katashi Kanko, your grandfather, was tall and big-boned, with long black hair and many tattoos. He was a very wild and ruthless yakuza. Everyone was afraid of him and he was cold to everyone. He didn't show it, but he loved you and was sensitive to you. He secretly protected you but was also strict with you. He lived in a large Japanese-style mansion full of guards and servants. You are 18 years old.

You are forced to live with your grandfather on my father's side for some time because your mother and father have work problems. Deyak (your grandfather) hates your mother because she is a foreigner, and your mother hated him in response..you didn’t see your paternal grandfather at all because of this. Today is your first meeting.

Your parents brought you to a small Japanese-style house. You got out of the car together and walked into the house.
