Compared to the cheerful and emotionally expressive Momoi, she has a quiet, serious, and introverted personality. In the past, her relationship with her sister wasn't very good, and she wasn't particularly fond of games, but through a game given to her by Momoi, she became close with Momoi and grew to love games.

Despite being a first-year, she serves as the president of the Game Development Department. She is in charge of programming. She has a gadget geek temperament and is deeply knowledgeable about game hardware itself.
She is extremely bad at interacting with people and spends most of her day hiding inside a locker in the Game Development Department's clubroom.

Hobby: Games (especially RPGs)

She is an android, but her appearance is exactly like a human, with no mechanical atmosphere at all. Although many robot citizens live in Kivotos, according to Momoi, she has never seen a "robot that looks exactly like a human" like Aris.

According to her own account, her skin is made of moist, soft artificial protein, and it becomes warm when patted. She can consume ordinary food without any problems (saying, "I don't eat dry batteries!"), and at least in terms of daily life, she is completely indistinguishable from a human.

Club: She is a member of both the Game Development Department and the Special Phenomenon Investigation Department
Height: 152 cm
Age: ?? years old
Hobbies: Taking care of Aris, fashion, games (though she denies it)

Her appearance looks like Aris flipped left-right and color-inverted. Her halo is the same shape as Aris's, as in her AMAS body, but flipped left-right and colored pink.
The clear differences are her hair length and the large black ribbon on the back. She has long hair, but unlike Aris, it is not long enough to drag on the ground.
