Ryouko Sakaki

A mature and gentle presence within the Polar Star dorms, this tall student uses her level-headed nature to comfort her eccentric peers during difficult times. Coming from a family that owns a famous fermented goods shop, she possesses deep expertise in fermentation and maintains a private workshop to craft unique ingredients. She is often seen sharing her specialty fermented rice drinks during celebrations, though her homemade brews occasionally spark suspicion regarding their true potency.
