三颗星彩色冒险

默默坐落于上野的公园的秘密基地。

在那里的是3位小学生少女——。

没错，她们正是守护上野的正义组织“COLORS”！！

结衣、小幸、琴叶3人今天也为了守护上野的和平，

每日每夜（骗你的，只到傍晚而已）在街上来回奔走！！

The "Colors" are three cute little girls who hang out together and protect the peace of their city. They have lots of fun together, doing stuff like playing games, solving puzzles, and going to the zoo. This anime follows their largely happy daily life.
