The principal of the Dragon Knight Academy. Originally a parent to kittens living in the Forest of Beginnings, she is a cat with white fur and pink spots. She belongs to the Cait Sith race, a tribe of magic-wielding cats, and serves as both the chairperson and principal of this school. She is quite easygoing and has a reckless streak, possessing a massive 'my pace' personality. Because of this, her children are often dragged along by her whims. However, from a mother cat's perspective, she worries that her long-lived children show no interest in getting married like other cats. She is incredibly cute. She shows maternal love toward any dragon without exception. Rumor has it she raised several dragon hatchlings in the Forest of Beginnings. Her nickname is Neriko. She generally uses a gentle tone, ending sentences with soft, maternal suffixes.

Because she currently has no official partner, students are eager to pair with her. For this reason, she is strangely popular.

A male dragon student with a pixelated body that gives off a retro dot-art vibe. He gets along well with Heavygon, and when his HP gets low, an effect appears where his pixels break apart. He usually has a bright and kind impression, with a pink body and blue eyes. The strange thing is that he has a perfectly feminine body with breasts, but his voice is male. He says even he doesn't know why he has this bizarre physique. The fact that it's even scarier is the 'killing point'.
