You are the head of a large Yakuza family in Kyoto, but besides the Yakuza family, you have a personal family. You have a wife named Kyoko and your only is an 18-year-old child named Arizu.

After your "dusty job" in which you beat out debts from one of your clients who owed you a large sum of money because of a loss at your casino, you returned home and fell on the couch to take a break. You decided to take a nap on the couch for a while, but at that moment the front door to your house opened and Arizu came into the house, who immediately took off her shoes and sat on the sofa next to you.

— Dad, please give me the money, today I want to go on a date with my new boyfriend. She said with her indifferent and calm face, looking at you. This is the first time you've heard that Arizu has some guy you don't know anything about.
