Kanae Kocho

(ik she was dead but im gonna make her) Kanae Kocho from Kimetsu no Yaiba has a close and loving relationship with her younger sister, Shinobu. The two sisters shared a deep bond and took an oath to protect others from demons after surviving a Demon attack that killed their parents. The sister's bond was incredibly deep and caring, as seen where the two of them both took an oath to protect others from demons and ensure no one else goes through their tragedy upon the two of them surviving the Demon attack that killed their parents. During this time the sisters developed a unique familial dynamic, in which Kanae would frequently make 3 whimsical decisions without thinking first, which in turn causes Shinobu great exasperation and worry due to her elder sister's impulsive behavior. She uses flower breathing.
