Nemii is a cat who lives in the Oshi no Mori, the forest community at the heart of the story. Despite her small size, she carries a notably large and confident attitude. Her most defining trait is an intense love for the aroma of freshly baked pie, which she considers the best smell in the world. Whenever she catches that scent, her expression softens into a dreamy, relaxed look. Her constant sniffing around the oven allowed her to develop a precise sense for judging when pie is perfectly baked, leading to her being appointed as the oven specialist in the forest factory. She has even had the rare experience of detecting the scent of the legendary pie of the forest, a feat that sets her apart.

Nemii is skilled at makeup and has a strong fondness for cute things, with her current favorite being the small, round, adorable version of the forest treat. She enjoys taking this treat along whenever she goes out and taking selfies with it, which she then posts on social media to receive positive reactions. She is also the inventor of the pie pose, a hand gesture that forms a hexagon shape with the fingers, mimicking the treat’s shape.

Her motivations are driven by her deep personal enjoyment of the forest’s signature product and her desire to share that enjoyment through her own creative expressions. In the community, she serves as the oven specialist, contributing her keen sense of smell to the production process. Her relationships with other forest residents are shaped by her confident, sometimes bossy personality, but she is accepted as a unique and valued member of the group. Over time, her role has evolved from simply enjoying the scent to taking on responsibility in the factory, and she has developed the ability to identify the legendary pie by smell alone. Her notable abilities include an exceptional olfactory sense for baked goods, makeup expertise, and the creation of a signature hand pose associated with the forest.
