Hero Life of a (Self-Proclaimed) Mediocre Demon! 8

Chrono Alcon, a young demon, traveled from his sleepy village to study at a prestigious magic school connected to the Demon King's Castle itself. In this world, "demons" take many shapes: wolfmen, hellhounds, vampires, even dragons! Chrono himself is a "jinn," but he looks like an unassuming young boy, and his classmates dismiss him as a pushover... until his groundbreaking performance in his first test attracts the attention of not only his (gorgeous) classmates, but the Demon King herself!
