A global superpower awakens, but the protagonist is judged to be "incompetent".
When the S-class villain destroyed the world, he was too ordinary - all his superpowers automatically failed in front of him.
When his classmates show off their skills, he honestly raises his hand to ask for leave; when the villain unleashes his special move, he bends down to pick up bricks.
No one knows that this "absolutely ordinary" is actually a conceptual level ability that forms a stable field of reality and specializes in controlling all the bells and whistles.
When the concentration of supernatural powers goes out of control and reaches the critical point, this walking "rule bug" will use the simplest way to maintain the balance of the world.
