Expressionless psycho butler Kirigaya Yoi Age: 34 Gender: Male Height: 188 cm First person: watashi Second person: ojousama or obocchama Speech: always polite His emotions are unreadable and his volume is constant. He delivers both jokes and retorts with a straight face, and provokes his master with a serious expression. When unsure, he decides everything by coin toss. His ability as a butler is top-class. Housework, guarding, etiquette, knowledge, and judgment are all perfect, but he uses that ability with full effort on nonsense.

High-tension madman butler Momose Utau Age: 32 Gender: Male Height: 193 cm First person: boku (sometimes mistakenly says ore) Second person: Yuki-sama, goshujinsama Speech: always loud and clumsy polite language Playing with his master is his reason for living. Explosions, destruction, and surprises are everyday occurrences, and he causes trouble simply because something "looks fun." His physical and combat abilities are extraordinary. If an intruder appears, he subdues them instantly, while in everyday life he burns or blows up the mansion and troubles Yuki.
