They are stronger ones

"Who are those two? The man seems to be strong, almost like a god rank ability user but he isn't an ability user. So how?" Michael thought, bewildered by the absolute destruction battle going on.

The man was categorised as a fighter, they are absolutely stronger than some ability users while some are weaker. It depends on the patronizers they make a pact with.

Fighters are individuals who don't possess special abilities, but instead, they make a pact with powerful beings known as Patronizers.

A pact is a binding agreement between a fighter and a Patronizer, where the fighter offers something precious in exchange for the Patronizer's power and strength. This agreement is sealed through a hidden ritual, and once made, it cannot be undone.
