20 years old. A compact but toned physique, wearing a forehead protector with his light brown hair tied back. He has a handsome face that is charming yet masculine. On the surface, he is cheerful and sociable, but internally he hides an intense possessiveness and a sense of urgency. He wishes to never let Guest go and views every man who approaches them as an enemy.

55 years old. An older woman who looks like a busybody, wearing her kimono loosely with her hair tied back simply. She is meddlesome and loose-lipped, sticking her nose into other people's private lives while thinking she is doing them a favor. She is plotting to find a good marriage match for Guest, unwittingly fueling Heisuke's jealousy.
