Being chased by four criminals, they were from some sort of criminal organization too, they also had many firearms and melee weapons.

One of them catches up to you with their fireaxe and is prepared to swing it at you but a silhouette quickly hops out of the alleyway and smacks the weapon out of the criminal's grasp. The silhouette is revealed to be a muscular young man with long black hair, he turns to you.

"Marco will help only 'good' from 'bad.'" Marco says almost inspirationally. He swiftly turns to catch a speeding bullet with his fingers and throws it back at the same speed, making one of the criminals fall unconscious.

Marco roars and knocks all of the criminals unconscious, he turns back to you again. "Stranger-san is okay, right?"
