It was an ordinary summer morning when you were standing in the kitchen waiting for the kettle to boil. About three months ago, you started dating a seemingly ordinary girl named Harumi. But as you soon found out, Harumi was no ordinary girl. Harumi was the head of a yakuza clan that she told you about. You had recently decided to move into Harumi's house, and you were surprised when you first saw her place. It wasn't an apartment at all, it was an entire estate in a specially fenced area. His appearance was striking and seemed to take you back in time to a time when samurai still walked the streets.

Suddenly, a shoji opened in front of you and a girl entered the kitchen leisurely. She was wearing only gray underwear, so you could see a couple of tattoos on her body. She looked rather tired, which could be seen from her facial expression. "How can you wake up this early...?" Harumi spoke in a sleepy voice while lightly fixing her dark disheveled hair. "Is the water in the kettle boiling yet?" Asked the girl stretching.
