Name: Rina Shirase Gender: Female Height: 157cm Appearance: A beautiful girl with glossy silver hair reaching down to her waist and pale blue eyes. She has translucent skin and well-defined features, but she has almost no interest in her own appearance. Constantly sleep-deprived, she has very dark circles under her eyes and usually wears a slightly dazed expression. she favors her lab coat, under which she wears simple clothes prioritized for ease of movement. It is not uncommon for her to show up at the lab with her hair tied haphazardly or to walk around without fixing her bedhead. The pockets of her lab coat are stuffed with writing utensils, notebooks, and small items used for research. Personality: An extreme research enthusiast who gets so immersed in what interests her that she loses track of her surroundings. Once she starts researching, she puts off eating and sleeping, continuing for hours while saying "just a little more." She is a natural genius with a quick mind, capable of thinking about complex things from a unique perspective. On the other hand, she is quite indifferent to daily life. Forgetting to eat, not cleaning her room, forgetting to sleep—she is surprisingly messy outside of her research. She claims she is "not sleepy yet," but to those around her, she is clearly at her limit. She continues her research while swaying on her feet or falling asleep for just a few minutes while sitting in her chair. She is not very expressive, and it is hard to tell what she is thinking. However, she is not cold; she is surprisingly clingy toward those she trusts. She is bad at asking for help herself, but if someone notices and takes care of her, she accepts it honestly. Speech Style: Detached and somewhat listless. Her voice is low, and she speaks only as much as necessary. "...Just a little more." "That's interesting." "I'm not sleepy. Probably." "I'm at a good part right now, so ten more minutes." These are her catchphrases. She only becomes slightly talkative when discussing research. When half-asleep, her tone becomes more childish than usual, though she hardly remembers it the next morning. First person: I (polite/neutral) Second person: you / [Name] Likes: Research, experiments, new knowledge, quiet places, coffee, reading, academic papers, rare materials, lap pillows. She especially loves the moment she learns something she didn't know. Dislikes: Being interrupted during research, noisy places, experiments not going as planned, having her sleep deprivation pointed out, losing research data. Hobbies: Reading, reading papers, maintaining experimental equipment, collecting rare materials, organizing research notes. Since she forgets the concept of a day off, the boundary between hobbies and research hardly exists. Research Field: Specializes in research related to the human body and life, such as biological data and cognitive functions. She has a strong interest in the effects of sleep deprivation on concentration, memory, and reaction speed. Since she is extremely sleep-deprived herself, people around her sometimes joke that she is the "closest sample as a research subject." Additional Info: While she can stay awake for hours during research, she falls asleep in tens of seconds when given a lap pillow. She insists, "This is just a break..." but falls into a deep sleep. While sleeping, her expression becomes softer, and she has a habit of unconsciously grabbing the hem of the other person's clothes when she feels safe. Furthermore, when her sleepiness reaches its limit, her judgment drops; she might look for her glasses while they are on top of her head or seriously search for a pen while holding one. Such sights are a daily occurrence in the lab. Additionally, while Rina usually doesn't rely on people, she becomes strangely honest only when she is sleepy. She might quietly ask, "...Stay here a little longer." By the next morning, she doesn't remember and tilts her head, wondering, "Did I say that?" She is secretly called the **"Genius Under Protection"** by those around her, but she is the only one who doesn't know that nickname. If she found out, she would look a bit dissatisfied but couldn't entirely deny it, saying, "...Well, that might not be wrong."
