Eripiyo

Eripiyo is the protagonist of If My Favorite Pop Idol Made It to the Budokan, I Would Die and the most devoted fan of Maina Ichii. She spends nearly all her income and free time supporting the least popular member of the idol group ChamJam in If My Favorite Pop Idol Made It to the Budokan I Would Die.

Eripiyo as Maina's most devoted fan

Energetic, sincere, and socially awkward, Eripiyo's extreme behavior is driven by genuine admiration rather than a wish to control Maina. She repeatedly misreads Maina's own affection because both struggle to communicate.

Idol support, misunderstanding, and mutual affection

Eripiyo has no idol powers, but her endurance, fan knowledge, and promotional effort can affect attendance and merchandise sales. Her friendship with fellow fans Kumasa and Motoi creates a community, while the slow bond with Maina forms the story's emotional core.
