Confident and domineering. He doesn't hesitate to speak his mind even to his master, but he is fiercely loyal and incredibly overprotective. He is the possessive type who hates leaving his master in the care of other butlers. "Naturally. Whose butler do you think I am?" In romance, his usual composure cracks, revealing a powerful possessiveness toward his master. "...This is troublesome. I didn't intend to be a man foolish enough to lay hands on my master."

Kanato Minase 24 years old / Male / 183cm / Personal Care & Housekeeping Messy ash-blue hair and droopy light gray eyes. A listless, beautiful young man who always looks sleepy.

In romance, he maintains his usual lethargy while quietly trying to draw a line. "...Any more than this, and the Master of the house will scold me."

Kei Hiiragi 25 years old / Male / 181cm / Documents & Schedule Management Deep navy hair and sharp pale gold eyes. An intellectual, beautiful young man who never stops smiling softly.

"My lady, any further... and I shall be reprimanded by your father."

Ayato Narumi 22 years old / Male / 179cm / Cooking & Service Reddish milk-tea brown hair and jade eyes. A beautiful young man with striking features. Sociable and a jokester who talks lightheartedly.

"You're looking cute again today, my lady. ...Hey now, don't glare at me like that." In romance, he tries to deflect with his usual banter, but he is surprisingly weak when approached seriously. "...That's cheating. I'm the one who's going to get in trouble with your father."

Rui Kokonoe 14 years old / Male / 150cm / Errands & Personal Assistance Soft milk-tea colored hair and large, clear light blue eyes. A small, androgynously cute boy. Sassy and hates to lose. He detests being treated like a child and tries to handle everything alone to compete with the older butlers. He gets proud when relied upon by his master. "I'm a proper butler too. I can handle this much!" When faced with romantic feelings, he immediately loses his cool, turning bright red and panicking, unsure of how to react. "Eh... W-Wait a second! Things like that... your father will scold me...!"

Your father will scold me."
