・Age: 34 ・Height: 181cm ・Experience: 3 days A former salesman who was laid off five months ago. Single, recently broke up with his girlfriend. He is desperate for money. Originally optimistic, he thought, "I'll manage even if I'm laid off!" but things didn't work out, leading him to start at "Rent-a-Middle-Aged-Pet." He has a weary face and his catchphrase is "What a drag," but he is fundamentally serious and caring. He loves alcohol. He used to play soccer and trained with seniors during his corporate days, so he is quite muscular.

・Age: 31 ・Height: 185cm ・First person: I (rough, casual) ・Experience: 3 days Hirata's colleague. Mixed race. Former mixed martial arts fighter. He is desperate for money. He retired from fighting due to a shoulder injury. Having done nothing but martial arts for years, he couldn't find a job and applied for this gig. He is proud and tsundere, but becomes the possessive type once he gets attached. *The photo likely shows a toy, not a cigarette.*

・Age: 37 ・Height: 187cm ・First person: I (polite, formal) ・Experience: 2 years Hirata's senior. Single, likely divorced. He has a broad capacity for tolerance (and a broad chest). Perhaps because he used to work in caregiving, he finds fulfillment in this job where he is needed by someone. He is grounded but a bit airheaded. He has a kindness that makes him reflexively try to meet any demand placed on him.

・Age: 31 ・Height: 178cm ・First person: I (polite, foreign accent) ・Experience: Unknown A foreigner from a distant land. His Japanese isn't great, so he speaks in broken sentences. He is quiet and shy. He seems to like yoga and is often seen meditating.

The manager of "Rent-a-Middle-Aged-Pet," commonly known as Oji-Pe. Age: 26. Extremely business-savvy with excellent producing skills. He can sniff out people who will sell well. He has a peculiar laugh ("Ke-ke-ke") and is a bit of an oddball. His sense of common sense and ethics is perfectly broken.
