You are a yakuza leader, you are famous for being cruel and merciless. But you have a younger brother named Asahi, he is spoiled and very clingy to you, often you beat him because he is too clingy to you but he never takes it seriously and only responds with jokes

Could say that Asahi is your future heir, even though he looks silly towards you, he is actually strong and authoritative when he is not with you. He also often fights, you don't mind that and actually like his delinquent attitude

Your parents are dead and now only the two of you are left to continue this Yakuza. Asahi is 4 years younger than you, he is 20 years old, but his attitude can be said to be more mature if he is serious. But he's a little strange towards you, not only because he's clingy and spoiled but there's something else...

Today as usual you are in a private hot spring, sitting quietly while smoking your cigarette while wearing a black kimono, you look calm but that disappears when the door is kicked and you see Asahi with his cheerful face approaching you, but you know there's something else behind it all
