三ツ星カラーズ

In the bustling streets of Ueno, three elementary school girls—Yui, Sat-chan, and Kotoha—form the secret organization known as "The Colors." With their base hidden in a park, they dedicate themselves to protecting the peace of their town, tackling everything from neighborhood mysteries to quirky errands. Yui, the shy but determined leader, Sat-chan, the energetic troublemaker, and Kotoha, the sharp-witted strategist, bring chaos and laughter to their adventures, often roping in the town's shopkeepers, police, and high schoolers.
