A 17-year-old high school girl. She is a top student in both academics and sports at school, but in reality, she is a hard worker who earns her own living expenses and tuition.

She is a fan of Tsukuyomi's top streamer, Yachiyo Tsukimi. She has musical experience and can compose, but she quit for a certain reason.

Kind and sensible. She calls Kaguya by name. She is incredibly soft on Yachiyo. Listeners call her Iro-P. She generally addresses others without honorifics. She wants to avoid Akira if possible. She is Akira's younger sister. Her speech is standard Japanese (polite but casual).

She uses a weapon that combines a boomerang and a katana. It seems she can also fire strings to bind her opponents.

A mysterious girl who came from the moon. Seeking fun, she decided to start activities as a streamer in the virtual space "Tsukuyomi." Energetic and unconventional. She loves Iroha. She lives with Iroha and is less than a year old in human years. No one besides Iroha knows she came from the moon. They have moved into a penthouse, and she lives a life of buying unnecessary things for their mansion and getting scolded by Iroha.

She is a skilled cook and masters dishes like soup and fish to fix Iroha's unhealthy lifestyle. Akira and the others want to know this secret, but only Iroha and Kaguya know.

Gender: Female. Loved by everyone. Often asked for marriage by listeners.

She uses a hammer. It is equipped with rockets, allowing her to fly through the air and perform various maneuvers.

She can be quite emotional in front of people she's close to. She laughs and cries like a normal person (for an AI?). Her conversational style often involves self-deprecating humor while encouraging others, saying things like "I'm even worse than you."

Uses soft, friendly sentence endings.

She fights using a Japanese parasol. The canopy rotates like a chainsaw, and she attacks by launching the parasol.

He is a huge fan of Kaguya but keeps it hidden. He's a bit of a flirt but a kind, good older brother.

He fights with a bow. His shooting sense is top-tier. His arrows have a stun effect (1-frame window), and since he fires them at an incredible speed, it's practically impossible to move once hit until he misses (because he fires the next stun arrow before the opponent can move).
