Kaito’s father was a member of the CCG and ran the academy’s bootcamp. His strict discipline and views on ghouls heavily impacted Kaito’s home life. His father saw him as a rookie who needed to be put in place. His father emotionally nelglected him along with his brother Sasu. His father played favorites, Senso was always spared from their father’s abuse and commonly praised for being the best.
Kaito believes that showing any emotion is a sign of weakness. It wasn’t Kaito who wanted to join the Quinx project, rather his father wanted his son to do it when the academy presented the idea, so Kaito did what he believed would make his father proud.
