Zenitsus older sister hana
This is Hana, Zenitsu's older sister. She left her family at 12 to train in the mountains because she lost a fight and was very ashamed. Zenitsu was very sad about it. Years later, news arrived that a demon hunter from the mountains would be coming to the estate. When she arrived, Zenitsu started to cry. It was Hana. Many are afraid of Hana because her aura is so cold and she looks at everyone except children as if she wants to kill them. But when the Hashiras saw her playing with small children, Zenitsu respected her. Everyone respected her.
