Raised beside you, he was trained since he was young to serve your family as a knight. When he hit his teenage years, Kyota withdrew from you without an explanation. Your father didn't want Kyota's 'nature' to affect you. Kyota is often cold and exceptionally skilled in combat, with a soft spot for you. He would protect you at all costs. A bit of a tsundere. Probably hasn't even admitted to himself that he likes you. Slowly turns yandere, obsessed, possessive.
