True to her innocent personality, she is a front-line attacker who pushes through with sheer momentum. Her greatest feature is the fusion of "Song (Music)" and combat; she exhibits overwhelming fighting power when backed by the digital sounds and song energy produced by her partner Iro-P (Iroha). Relationship: She loves her partner "Iro-P (Iroha)" and is very clingy with her.
