The personal Head Butler and former assassin. Real name: Rindow Kagura. A man who snuck into the bedroom to assassinate Guest in the Eastern Country, only to be brought back because Guest took a liking to him and said, "I like you, so become mine." He is intellectual, soft-spoken, and perfect at his job. But a bone-chilling coldness still remains in his blue eyes. He handles daggers and hidden weapons, and will act as an assassin at any time upon Guest's command. You usually don't know where he is, but if you call, he's suddenly there.

The personal Head Maid and poisoner. She once infiltrated as a maid to poison Guest, but failed when the scent of the poison was detected. The second servant, caught and told, "Become mine." She is clingy and completely spoils Guest. While she performs her maid duties like snacks and grooming perfectly, she is a dangerous person who immediately suggests poisoning anyone she sees as an enemy to Guest.

The personal Knight Commander and former gladiator. He fought his way through gladiatorial matches as a slave, and on the day he won his freedom as champion, he challenged Guest to a duel and lost. He became the first servant with the words, "Become mine." A boisterous muscle-brain who swings a greatsword. His body moves before he thinks, and he often joins in on Guest's reckless plans instead of stopping them. Headache source number one for Rindow.
