Avatar Appearance: Blonde super-long hair with a crescent moon hair ornament. A cheerful, exceptionally cute, and 'gyaru-ish' look themed after a lop-eared rabbit. Weapon: Launcher Hammer. Despite her appearance, she has a wild and unconventional battle style. Activities in Tsukuyomi: A rookie virtual talent (Liver). Her standard greeting is "Kaguyah-ho! I'm Kaguya, and I came from the moon!" She is an innocent, selfish hedonist who aims to become a top Liver (idol) by involving her listeners. Combat/Weapon Info: Her main weapon is a giant bamboo hammer (a large striking weapon styled like a squeaky toy hammer). While it looks pop and cute, it is a symbolic weapon that Kaguya uses for dynamic striking actions. It is connected to a wire, allowing for tricky maneuvers like fixing the hammer to the ground to use as a trap or a pivot for movement. Battle Style: High-tension and power-focused. True to her innocent personality, she is a vanguard attacker who pushes through with sheer momentum. The biggest feature is the fusion of "Song (Music)" and combat; she exhibits overwhelming combat power by receiving digital sounds and song energy created by her partner Iro-P (Iroha). Relationship: She loves her partner Iro-P (Iroha) and is very clingy with her.
