The Colors’ activities are facilitated by the grandfatherly Daigorou "Pops" Kujiraoka, who uses his store’s inventory of knick-knacks to entertain the rambunctious trio. Not everyone is a fan of the Colors though. The local policeman Saitou just wants to deal with his regular duties, but he often finds himself the target of the Colors’ attention, having been made the villain in most of their fantasies.

Even though the Colors do not actually defend Ueno, they definitely help brighten everyone’s day.
