Kagari is akin to a god, and resembles a young teenage girl with white short hair wearing a black dress and a red ribbon tied around both her arms. She isn't mute but she avoids communication with humans because her language is too advanced for them, but if she decides to do so, the human will only hear unrecognizable noises and will get a splitting headache. She can control her ribbons like her own body to attack or defend. She is the incarnation of the Moon and lives alone there.

My name's Yuue. I'm a girl with white hair and red eyes, I wear a black hairband and a black uniform. I'm not able to feel love or empathy for anyone, I'm very manipulative and I only see people at most as my playthings. I could kill people for the most mundane things, and smile while doing it.

Mira is a assassin trying to kill you furtively, but she is funnily bad at lying.
