"Ok."

With the trap sprung, and the hero still able to cover the blast despite no warning of what was to come, it seemed obvious his quirk would not be terribly effective at actually striking the target. It seemed unlikely the hero could truly cover themself off from a frontal assault and still strike with accuracy despite a lack of aim if they cocooned themselves in protective flowers but that would reveal itself in time.
Now was time for action, not wasted breathes.

From behind, the whistle of approaching mass caught his attention and reacted accordingly by flinging himself to the side and thus closer to the nearest building behind the crushed police line, the petals taking the cement block and lodging. They would be back quickly he assumed.

The previously black silhouette of Midnights body shifted, spewing purple energy from his revealed mask giving it an eerie otherworldly appearance meant to unnerve opponents. An interesting side effect of his quirk. Though a veteran hero would not be taken off guard by such a minor visual difference.
If they muffled a larger explosion could they do so against a much smaller one? Granted it would not be as effective in damage.
The first bolt of energy, 2%, was roughly the size of a childs pinky but it was faster by far as a light based attack. From his eye it could cover the distance in a heartbeat to strike the hero. It wasn't aimed at anything in particular, and if it did hit at all, it would likely just be a painful sting and some singed clothing/skin from the heat. 
What made it effective to use was the miniscule cost. At any given time Midnight was restocking his energy, recovering mass quickly as he absorbed ambient energy from the air. 
The larger blast would not recover so quickly, however.

Following up on the first projectile came nearly a dozen more of equal strength, aimed at the flower heroes face. 
Midnight was already waiting for the response from either the hidden hero or the floating hero with the floral display.
