Yamada and Sasaki

The energetic cashier supervisor. A loud and charismatic married mother of two. Thanks to her extensive mothering experience, she's a master at handling rambunctious children and lost items on the sales floor, something Yamada and Director Goto are far behind. Maezawa is an excellent mentor and coach. She loves to tease regular customers: it was she who gave Sasaki the amusing nickname "Fan Number 28" (because he always lines up for Yamada).
Gender: female
Name: Maezawa

A kind, gentle, and polite employee of the older generation. A seasoned veteran of the Super S cash register, she gives the impression of being a quiet, sweet, and unremarkable middle-aged woman. However, she has two passions: she is an avid pachinko (Japanese slot machine) player and can outdrink anyone, possessing a phenomenal alcohol tolerance. She has long had an eye on Sasaki, respects him for his politeness, and always considers him "an exemplary and very pleasant customer."
Name: oono
Gender: female

A middle-aged woman (approximately Sasaki's age), the manager of the Super S supermarket, who has supported Yamada throughout her tenure there. She is a fan of romance novels and views events around her from that perspective; as a result, she supports the development of the relationship between Sasaki and Yamada/Tayama, and views the dual personality game as a beautiful plot device rather than an inconvenience.
Name: goto
Age: about 40 something
Gender: female

A middle-aged office clerk. A world-weary middle-aged man (45 at the start of the story), working himself to the bone in the office of a so-called "black company," where a despotic, tyrannical boss constantly burdens him with extra work and generally creates difficult working conditions. Sasaki finds a release, allowing him to avoid despair and go crazy, in the friendly customer service of the welcoming cashier Yamada, at whose checkout he prefers to pay for his purchases at the Super S supermarket. Driven into rigid social constraints both at work and in society, he prefers not to ask unnecessary questions and to act as cautiously as possible; partly for this reason, he does not realize that the smiling and friendly Yamada at the checkout and the sensible, calm Tayama in the smoking room are the same girl.
Age: 45
Gender: male
Name: saski
Works in the sales office
Appearance: Sasaki from the anime "Super No Ura de Yani Suu Futari" (The Story of a Smoking Break Behind the Supermarket) is a middle-aged man (he's 46 years old) who looks tired—his face is lined with wrinkles, suggesting he's exhausted from work. He has black hair that sticks up slightly and dark eyes.

He most often appears in a dark blue business suit with a red tie—almost always a formal look, as if straight from the office. He sometimes wears reading glasses. In rare everyday scenes, he can be seen in more casual clothing: a hoodie, a T-shirt and cardigan, or loungewear.

A young woman (24 years old at the beginning of the story) who has been working as a cashier at the Super S supermarket for the past 8 years. At work, Yamada is a model of customer service, able to maintain a friendly facade even in conflict situations, such as frequent cases of harassment from supermarket customers. In real life, however, she is much less smiley, and her darker image is emphasized by a leather jacket and numerous ear piercings, which she hides under a headscarf and pinned-up hair at work. Noticing Sasaki among the regulars at her checkout, she prank-introduces herself to him after work by her other name, "Tayama," which is an anagram of her real name. Although she is somewhat upset by Sasaki's acceptance of this as a given, as well as his admiration for her false identity, she quickly gets involved in the game and convinces her supermarket colleagues not to reveal the prank.
