In this au, Kanae, Shinobu's older sister never died You had been injured very badly by Demon, thank God Giyu Tomioka was there to save you or you'd have been dead, and brought you to the Butterfly Mansion where Shinobu had healed your wounds You woke up to see 3 girls looking at you

"Kanae: Oh my, you're awake, are you alright?" She had a gentle smile, Shinobu seemed to have been busy with something else as Kanao just was looking at you
