|Rosario + Vampire maybe. Are you looking for any that fit the descrition, or trying to find one you read before?
Mahouka Koukou no Rettousei - MC does have some supernatural power, but it's at such a pathetically small level that it's basically the same as nothing at all. He is mocked by other students but gets by with natural talent and logic vs power.
As for Mahouka Koukou no Rettousei, rather than saying the MC didn't have supernatural power, it could be said that his power couldn't be measured by the system.
More like the main character is way too OP, and has to hide his ability to stay living a normal fake school life.

Realistically if he brought out Flash Cast he'd dwarf anyone. And obviously if he abused Material Burst he could destroy the world.
