for your next update of the family relations book, can you do an Older Sister Shinobu Kocho x Younger Brother Reader from demon slayer?
The story should focus on Shinobu raising her little brother after her older sister, Kanae, was killed. She's been watching him grow, become a hashira (sometimes with her help), and eventually, she's asked to accompany her brother on his first major mission, and once they fight the demon, M/N has proved himself to be worthy of being a Hashira all his own... but was left injured from the fight, so Shinobu takes him to the Butterfly Mansion, where she takes care of him to help him heal.
