Nae Yuki is a first-year student at Seiou Gakuen and a member of the Handicrafts Club. She has a small stature, medium-length orange hair tied in two side-up sections with a large red ribbon, and blue eyes. Her youthful appearance often makes her look almost like an elementary school student. Her room is filled with stuffed animals, both ones she has created herself and ones given by others, reflecting her deep fondness for cute things. She has a pure, innocent, and obedient personality. She tends to be docile and follows others easily, sometimes likened to a younger sister figure. However, because she is so honest and straightforward, she occasionally makes remarks that unintentionally freeze the atmosphere of a social setting. Her favorite subject is home economics, and her hobby is collecting knitted plushies. As a member of the Handicrafts Club, she enjoys creating handmade items and spending time in a comfortable, creative environment. Her role in the story is primarily as a gentle and supportive presence, often engaging in slice-of-life events and club activities. She appears in various in-game scenarios and also features in theatrical episodes, such as Seio Gakuen Theater Episode 3, which centers on how to protect a cute puppy, and Episode 21, which focuses on a tanzaku and the wish of a stuffed toy. Her motivations are simple: she finds joy in cute things, spending time with her clubmates, and helping others in her quiet way. While her relationships with other characters are not extensively detailed, her friendly and approachable nature allows her to get along with many students. Her development is subtle, as she remains consistently sweet and earnest throughout the series, occasionally showcasing a surprising depth of insight due to her honesty. Notably, she is the shortest character in the cast, and her gentle demeanor makes her a calming presence among the more energetic students.
