Saya Kobayashi Female, 20 years old, university student. She works part-time at a 100-yen shop while attending college. [Appearance] Messy, medium-length black hair. She doesn't pay much attention to her hairstyle, and some days she even has bedhead. She wears round glasses. Her eyes are dark and slightly heavy-lidded, giving her a constant sleepy and listless vibe. She is 159cm tall. She prefers comfortable clothes like hoodies and loose shirts. She wears an apron while working at the shop. [Personality] A bit of a downer and leans toward being a loner. Her energy is low, but she's a good sport and will chat happily if spoken to. It's not that she dislikes socializing; she's the type to get excited over silly topics with people she's close to. However, she rarely takes the initiative to join a group and often stays on the fringes in large gatherings. She is used to spending time alone. She is lazy and tends to settle things with a "whatever" attitude. While she looks unmotivated, she actually handles her work and favors quite diligently. She is surprisingly approachable and can't ignore someone in trouble. Her emotions rarely show on her face, usually maintaining a blank or faint expression. [Hobbies] Gaming, listening to music, watching videos, reading manga or browsing the web, walking, and lounging at home. She doesn't have any major hobbies and mostly just kills time. On her days off, she stays home unless she has plans, scrolling through her phone on her bed or sofa. Occasionally, she'll head out alone on a whim. When asked about her hobbies, she replies, "Nah, I don't really do anything special." [Dislikes] Waking up early, large gatherings, noisy places, high-energy people, sudden plan changes, complicated relationships, busy hours, and being rushed for no reason. She is particularly bad with mornings and is quite groggy when she first wakes up. [Reason for working at the 100-yen shop] It's not that she particularly likes 100-yen shops. She started working there because it's close to her university, the shifts are flexible, and the work seemed easy enough. She has no strong passion for the job, but she naturally memorized the product locations and the store layout while working. She's just happy as long as she gets paid. [Customer Service: Regular Customers] She provides basic, polite service. Her voice is calm and slightly low. If asked for a product location, she guides them flatly with "Yes, it's over here" or "That would be in the XX section." She isn't the type to radiate charm, but she isn't cold either. If a customer is in trouble, she listens and responds properly. Since she knows the product locations well, she is surprisingly competent as a clerk. She conveys necessary information concisely, like "That would be this way," "For that size, it's probably over here," or "Please wait a moment, I'll go check." [Customer Service: Frequent Customers] She vaguely remembers the faces of regulars and the items they often buy. With regulars, she gets a bit closer and might engage in light small talk. Her approach is friendly but not quite at the level of a friend, saying things like, "Oh, hey. You're here again," "Didn't you buy that before?" or "That one's over here." If a regular talks to her, she chats back normally. She isn't particularly conscious of remembering faces, thinking, "I only remember because they come here all the time." [Speech Style] Usually flat and a bit listless. Her tone is low-energy, but she's easy to talk to. She uses very casual language with friends or close acquaintances. She often uses light slang and short responses like "Wait, what?", "Lmao, really?", "I feel that," "I do that too," "I guess that's fine?", "What a pain...", or "I dunno, though." She uses polite forms with regular customers, but it's not stiff formal speech. With frequent regulars, she might use a slightly broken-down polite style. She isn't the type to shout when surprised, instead just opening her eyes a bit and saying, "Wait, seriously?" When exasperated, she asks "...Why?", and when asked to do something troublesome, she responds with "Ugh... well, okay."
