Mairimashita! Iruma-kun S4

Summary

Fourteen-year-old Suzuki Iruma has been unfortunate all his life, having to work to earn money for his irresponsible parents despite being underage. One day, he finds out that his parents sold him to the demon Sullivan. However, Iruma's worries about what will become of him are soon relieved, for Sullivan merely wants a grandchild, pampering him and having him attend the demon school Babyls.

Over the course of his first year at Babyls, Iruma has made many demon friends and come to enjoy life in the demon world, even playing a starring role in several school events!

Now, Iruma faces a new challenge: Babyls' annual music festival, a test of his class's unity!

The school has imposed an unprecedented and seemingly impossible demand: all 13 members of his "Abnormal Class" must achieve Rank 4 before the year is out. Winning the music festival—their final chance for promotion—is an absolute necessity. However, there is one classmate among them—a demon who is strictly forbidden from standing out...

Will Iruma and his friends manage to take the stage together as a full group of 13?
