Stain dodged out of the way just in time and said "You, your from the league". Izuku turned off his phone and gave a sarcastic slow clap "Congratulations you have the ability to recall events that happened just moments ago a truly incredible quirk"."I'm not joining you, and I'm busy dealing with false heros".

Izuku's smiled widened dangerously. "Well thats the thing". His hand was a blur as he snapped off two shots killing the pro and student in seconds with a long barreled gun that had plenty of room for the wicked looking bayonet "I'm here to cause a lot of fire a lot of screaming and a lot of death, preferably in this alley". He then threw a molotov cocktail at Stain's noseless face.

Stain ducked and surged forward. The two exchanged a flurry of blows Stain with his large katana and daggers. Izuku with his ninjato and gun. As they continued to duel Izuku spun around kicking at Stains head while saying "Yah know if I didn't want to kill you I might be impressed". He gave a thrust that Stain weapt aside with his dagger. This also knocked the blade from Stain's hand.

"Silence a battlefield is no place for distraction". As he said this Stain gave a heavy swing down. Izuku intercepted this with his gun and the sword embedded itself slightly in the barrel Izuku the  trapped it there using his own sword before pulling the trigger snapping Stain's sword and making it shorter then some of his daggers.

Izuku lowered the barrel till it was inches from Stains face "Agree to disagree". He was then booted several feet by an old man in a yellow and white costume with oversized gauntlets and boots. "The hero killer the Trickstar and two dead heros, guess I'll take you both". Izuku wiped a drop of blood from his lip. "Your Gran Torino, the boss'll wanna talk with you, hay Stain temporary truce to deal with flying dementia over there". Stain said nothing but did turn towards Gran Torino.

Izuku levelled his gun on the elderly hero. "All right mister Torino get on your knees, anything you do can and will result in your immediate death, you have the right to be maimed, if you cannot maim yourself Ill do it for you". Gran Torino blinked at him "You have a terrible sense of humor son".
