Caramel Devils

A six-year-old boy named Robin Verall, who is determined to become a notable devil in Hell's history, begins attending Hell Academy elementary school. He dislikes school and often hides in unusual spots, which leads to difficult situations. His homeroom teacher, Shiba-sensei, finds him in one of these places and helps him out, causing Robin to develop a stronger bond with the teacher. He then devises various challenging plans in an attempt to spend more time with Shiba-sensei.
