三ツ星カラーズ

Three grade-schoolers, Yui, Sat-chan, and Kotoha, run a self-appointed vigilante club called the Colors out of a wooden hut in a park in Tokyo's Ueno district. Yui heads the club in name, Sat-chan supplies the energy, and Kotoha the schemes, as they hand out 'missions' and chase pretend cases around the neighborhood. More often than not, their crusade to keep the peace is what disrupts it.
