Chibiki is a puchidol, a small, chibi-like creature, who appears in the anime series. This character specifically resembles the human idol Hibiki Ganaha, sharing her long black hair styled in a distinctive ponytail.

The background of Chibiki begins with her unusual introduction in the story. Hibiki Ganaha had been expressing a desire to have her own puchidol companion. In response, another character, Takane Shijou, presented Hibiki with a catfish that was carrying Chibiki in its mouth. This initial encounter led to an adventure where Hibiki and Chibiki became stranded in Brazil. While waiting for a way to return, the two quickly formed a close bond, and Chibiki ultimately decided to live with Hibiki, who became her caretaker.

Chibiki is depicted as very energetic, reflecting the cheerful and lively nature associated with her corresponding idol. Her personality is closely tied to her unique and notable ability. Whenever Chibiki cries or sheds tears, she summons various animals. These creatures can range from common animals to legendary beasts, and Chibiki demonstrates the ability to easily control them once they appear. She is also shown to be a skilled swimmer.

The primary role of Chibiki in the story is that of a companion to Hibiki. Their key relationship is defined by mutual care and the bond they formed after their first, somewhat chaotic, meeting. Chibiki's motivations are largely driven by her connection to Hibiki, and her actions, particularly the use of her summoning ability, occur as an emotional response to distress or sadness. Information regarding any significant development or change in Chibiki's character throughout the course of the anime is not available.
