Muse of the Black Handed (SakuAtsu)

Sakusa Kiyoomi is a well known underground yakuza boss who is a former assasin that's why he's known as the scariest yakuza boss ever existed in the underground yakuza world.

He has a daughter with selective mutism named Sakusa Kitsumu. She's apathetic. Kitsumu always had that resting poker face on her face. The last time she smiled was before her mom died.

Until one day, after Kiyoomi picked up his daughter. To his shock, Kitsumu had a bright face and the little girl really looked happy and excited.

"Daddy, the new teacher is so pretty! He is sooo nice too!" Kitsumu said, motioning her hands.
