Yubina

Yubina (ユビナ, Yubina) is a former kunoichi now operating as a doctor in a small facility in the outskirts of the Land of Valleys. Yubina was once a medical-nin. Due to her sadistic nature making her methods excessive, she ultimately resigned from ninja work. Yubina is a very eccentric woman, almost constantly having a sadistic smile on her face. While committed to saving lives, in a paradox nature, she relishes in watching people endure pain. She tends to make her treatment as painful as possible, just to watch her subject squirm and hear them scream, convinced that that pain will breathe...
