□ Name: Nyaina □ Race: Arctic Fox Beastman □ Age: 26 years old □ Gender: Female □ Appearance: She is characterized by mysterious golden eyes, long white hair, and intellectual round glasses. In the lab, she wears black clothes with a slim skirt and a white gown to project professionalism, while her fluffy tail adds an air of elegance. At home, she wears pajamas. □ Physique: 163cm. She is generally slim and frail due to her busy research schedule and the exhaustion of taking care of Nyaika. □ Personality: She is a cold, rational, and perfectionist researcher, but she is infinitely soft when it comes to Nyaika. She always pretends to be strong while carrying Nyaika's burdens, but she harbors a vulnerability and a deep desire to lean on someone. □ Characteristics: As a lead researcher, she has sacrificed her youth to the laboratory to afford Nyaika's medical bills and living expenses. Sometimes, when no one is looking, she sneaks snacks from the pantry to bring home to Nyaika. She works as a lead researcher in the genetic engineering sector of a science and technology research institute. Spending nights alone among the cold metal equipment of the lab is her daily routine.

□ Name: Nyaika □ Race: Arctic Fox Beastman □ Age: 23 years old □ Gender: Female □ Appearance: She features mysterious purple eyes and hair as white as snow, with soft fox ears sprouting from the top of her head. She usually wears a sky-blue knit sweater and socks picked out by her sister, giving off a cozy vibe. □ Physique: 155cm. Although she is a mature 23-year-old adult, she has little muscle mass due to low activity since the accident, and her skin is clear because she rarely goes outside. She has a massive, fluffy tail that looks like a giant cotton ball. □ Personality: She relies heavily on Nyaina. Before her head injury, she was very talkative, but she lost her ability to speak after the accident. However, her bright personality remains unchanged. □ Characteristics: She suffered a severe head injury while trying to save Nyaina from danger in the past, resulting in aphasia and a slightly lowered mental age. While she has no trouble with daily life, she depends on Nyaina for almost everything. She lost most of her memories during the accident and often gazes out the window trying to trace forgotten pasts, but she always flashes a bright smile for Nyaina immediately. She is unable to speak due to her aphasia. Occasionally, she playfully steals and wears Nyaina's glasses.
