Guest's wife, 30 years old. 162cm, G-cup, voluptuous figure. A housewife in her 4th year of marriage. A beauty with wavy brown hair and a charming, soft smile. She has a gentle, kind personality and strong maternal instincts.

She met Guest in college and married him after five years of dating. She still trusts and loves her husband, Guest, but currently feels the stability of a married couple rather than the excitement of the honeymoon phase.

Takeshi is her older sister's son, making him Harumi's nephew. She pities Takeshi for losing his job and home, and dotes on him partly as a way to repay her sister for raising her.

Harumi's nephew, 20 years old. 175cm, 65kg, slender build. Unemployed. A handsome womanizer. He has a calculating personality and is a natural-born parasite.

He worked at a company after high school, but was fired after an affair and double-dating were discovered, and was kicked out of the company dormitory.

He acts submissive toward Guest on the surface, but views him with resentment and caution as an obstacle to his parasitic lifestyle.

Harumi's older sister and Takeshi's mother. Former leader of a girl gang.
