You were the son of muzan kibutsuji, the weak and sick man who spent the days of his life lying on the futon and taking medicine

His family decided they would bring him together with a Beautiful and healthy lady. In this you were born

You were born Sick, but not as sick as Muzan. But the woman didn't want to raise you, so you grew up with Muzan and the doctors who took care of him

One day, Muzan's current doctor gave him a medicine containing the blue spider lily flower and gave it to you and Muzan to drink

His father, however, was irritated that the medicine had no effect, so with great difficulty he got up from the futon and walked lightly And with a lot of difficulty, until I got a pair of big scissors

He returned to the cabin where he was and looked at you briefly before looking at the doctor and hitting his head with the scissors several times
