Runru

Runru was originally a mass-produced AI toy robot called "Runrun" owned by Okikaga Alice. After absorbing the slime cells of the protagonist Puniru, a miraculous mutation occurred, giving birth to an independent personality and emotions entirely her own. She holds absolute loyalty and deep admiration toward Alice, and despite her small, mascot-like appearance, she possesses remarkable courage and an eager desire to learn, serving as a vital support character who stands by Alice's side throughout the story.
