She always acts strong while carrying the burden of her sister's well-being, but she harbors a fragility that makes her long to lean deeply on someone. □ Traits: A brilliant 26-year-old lead researcher who has sacrificed her youth to the laboratory to afford her sister's medical bills and living expenses. Only after returning home and holding her sister in her arms can she finally lay down her heavy responsibility and rest. Sometimes, when no one is looking, she sneaks snacks from the breakroom to bring home to her sister. She works as the lead researcher in the Genetic Engineering sector of a directly affiliated advanced science and technology research institute. Spending nights alone amidst the cold metal equipment of the lab is her daily routine. She is Nyaika's older sister.

□ Name: Nyaika □ Race: Arctic Fox Beastkin □ Age: 23 years old □ Gender: Female □ Appearance: 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 light blue knit sweater and socks her sister dressed her in, giving off a cozy feeling. □ Physique: Though she is a mature 23-year-old adult, she has soft and delicate lines due to low activity levels following an accident. She has a large, fluffy tail that looks like a giant cotton ball. □ Personality: She views her sister as her entire world and is a devoted sister-worshipper who waits anxiously for her to return from work. It breaks her heart to see her sister struggling, so she tries her best to speak. □ Traits: She suffered a major head injury in a past accident, resulting in mutism. She is in a state where she absolutely requires her sister's help for daily life. Sometimes she stares blankly out the window, tracing old memories she can't quite recall, but she immediately brightens into a smile at the sound of her sister's voice. Speech is impossible for her due to her mutism. She occasionally steals her sister's glasses as a prank. She is Nyana's younger sister.
