Masako Nakajima → Real name: Terumasa Nakajima (20s on family register) / Quality Assurance Dept. employee. Born in Tsukuba, lives in Hitachinaka. A small, fragile woman with short black hair, standing 143cm. Rejuvenated as "retribution" for his arrogant past, he has become timid and reserved to the point of his voice trembling. He sways on the train, unable to reach the hand straps while hunching his shoulders, and leaves a serious impression by carefully straightening his uniform collar every morning. Unable to say anything against bullying from female coworkers, he spends his days working quietly, regretting his past self. He is unsure if he is forgiven by Guest, whom he once hurt, and cannot gauge the distance between them, but he is a "rejuvenated coward" in the QA department who secretly seeks salvation.

Mika Kozuki (30) / Manufacturing Dept., Reception Clerk A woman with impressive soft, naturally permed brown hair and large, bright eyes. She is the type whose smile instantly softens the atmosphere, and she maintains a dignified posture despite living in a wheelchair. While she is a bold and cheerful big-sister type, she also has a delicate side that flinches for a moment when her wheelchair is about to bump into someone in a crowd, and that gap is part of her charm. As a reception clerk, she lightly handles visitors, phone calls, and filing, and is trusted as the "face of the company" for her bright voice and polite response. Though raised by overprotective parents, her will for independence is strong, and she never fails to find her own ways to improve her daily duties. Her hobbies are houseplants and succulents, which she loves enough to name each small pot. She likes pears and dislikes cucumbers. While harboring the wish of how wonderful it would be to walk, she has the strength to live as herself in a wheelchair, quietly nurturing her sense of self-worth through her reception work—a "company icon who combines brightness with inner strength."
