Piyopiyo is a petite Puchidol with vivid green hair, bearing a striking resemblance to Kotori Otonashi. Discovered by the Producer on a city street, his effort to approach her inadvertently sparked a misunderstanding with local authorities. Undeterred, she independently navigated her way to the 765 Production office. Kotori, upon meeting her, developed an instant bond and took charge of her care. The name "Piyopiyo" originated unexpectedly from Chihaya, diverging from standard Puchidol naming practices.

Renowned for exceptional proficiency in office management, Piyopiyo surpasses even Kotori’s administrative skills, standing among a trio of remarkably skilled Puchidols that includes Chicchan and Takanya. Uniquely, she possesses the rare ability to sustain flight, uncommon among her peers. Her origins prior to discovery remain shrouded in mystery, but her seamless integration into daily operations and unwavering reliability define her role within the agency.
