Hero Without a Class: Who Even Needs Skills?! is a fantasy manga based on a light novel series where everything is about class. The series is also getting an anime adaptation.

The main character, Arel, is the son of two powerful people: his mother is a sword princess, and his father is an archmage. Oftentimes people end up in the same class as their parents, so you might expect Arel to become a swordsman or archmage.

Once a person knows their class, they can acquire skills for it.
