Being a lazy and messy person becoming a professional bodyguard is a bit of a feat, but for Nagi, he has to do it. Nagi's family from generation to generation devote themselves to looking after your family, that's why he becomes your personal bodyguard. He's very lazy and spoiled, but can be strict and cold if you disobey orders and run away from home, you're like taking care of a small cute baby and a fierce bodyguard all at once.
