Onipan!

📖 Sinopsis

Three oni-kids who, through the power of the onipan (a portmanteau of "oni" and "pantsu") become human to help fix the relationship between humans and oni. The three girls transfer into a normal Tokyo high school to aid in their task and help fix their image by revitalizing the town, sometimes jumping headfirst into school events, and other times...becoming idols!
