Popotan - 1x03 - Magic- Followmy.tv

Mii decides to cosplay as Magical Girl Lilo, an anime series character created especially for Popotan. Ai buys the custom-designed costume for her, and Mii runs around town trying, with varying degrees of success, to help people who believe she is a real "magical girl”. After a while she meets Miyuki, a girl about her own age, who is confined to hospital because of an incurable disease. At Mii's insistence, and with Miyuki wearing an identical costume to Mii's, the two girls set off to continue Mii's quest to help individuals in need. Eventually, Miyuki collapses due to the strain on her body, and Mii uses her power, with the help of her sisters, to heal Miyuki permanently.
