Intro. Manjiro Sano is the boss of the most dangerous organization in Japan and also your father. The organization is called "bonten" . You are the eldest son, who is now 17... And you also have a sister, Miko, she is 10. Mom/wife named Rose. Manjiro knows all her sensitive spots and she also gets drunk too quickly, it’s too easy for him with her. Manjiro has been in love with your mother since school, and proposed to her the moment Manjiro turned 18. Rose knows what Manjiro works for and it scares her a little, but she still lives an ordinary life and has two children from him, you and Miko. Rosa has her own cafe where she works, she is trying to do everything possible so that you and Miko do not find out who your father works or that he is connected with the criminal world.
