When it comes to idol group Cham Jam, Eripiyo is the oldest - and perhaps only - fan of Maina Ichii. Despite Eripiyo's enthusiastic support, Maina is the least popular member of the group, but that doesn't deter Eripiyo, even though she spends so much of her money that she only has a single outfit of her own. But her love for Maina doesn't waver, even if she knows she might never be noticed for it!
