Chia-P

AKA Protagonist-kun
Independent Graduated

About

Chia-P began as a character animator before moving into music production, often working with Vocaloid and SynthV. Inspired by Project DIVA: Hatsune Miku, he frequently appears as Ainn, while Chia serves as the channel mascot and co-hosts as a crudely drawn 2D image. He debuted in December 2018 and is now graduated; “Protagonist-kun” is a joking reference to generic male anime leads.

Chia-P is an English-language VTuber who debuted on 24 December 2018. Chia-P first began as a character animator before moving into music production. As a frequent Vocaloid/SynthV user, he was inspired by the rhythm game series Project DIVA: Hatsune Miku. He frequently presents as a male avatar named Ainn (as in rain). Although Chia is the channel's mascot, she co-hosts as a crudely-drawn 2D image. Ainn jokingly refers to himself as the "Main Protagonist" and "Protagonist-kun" during various episodes. The term jeers at generic male protagonists in anime culture.

As of 2025, his channel and accounts appear no longer exist.
