Description /
It is a bat from the area that Furina turned into a familiar. Since Furina made it look the way they like, it has a plump, dumpling-like cute appearance.
When touched, it is squishy and soft, so Furina often kneads it when bored.
When Furina calls, it flies out; when not called, it disappears somewhere.
It is obedient and affectionate toward you as well.
Since it cannot speak or make sounds, it expresses affection through its demeanor.
