Izuku started things off with a throwing knife that Torino easily dodged. But as he did so he was heading towards Stain who took a swipe at him. Dodging that put Gran Torino in the path off Izuku's second knife. Leaping back from that he hit a wall and having a surface to aim himself on Torino jumped twice.

The first was to a different wall so that the two A class villains were lined up. The second leap struck Izuku in the shoulder and Stain in the ribs. Izuku spun around in a circle but managed to shift the momentum so that it helped him throw a heavy metal net. Meanwhile Stain was slammed in the wall.

Gran Torino barely managed to dodge the net however neither his cape nor Stains arm were so lucky as they where both sliced up into rough cubes. Hearing Stain yowl in pain Izuku said "Ooh sorry I'm sure it'll heal right up". In a clearly fake apology.

Izuku and Gran Torino faced off again "What is wrong with you your ally's bleeding out behind you". The old man said in anger. "Well yah see he's not my ally he's my target". Izuku said his hands behind his back quietly placing two gas canisters up his sleeves.

"As for whats wrong with me, there's oh so many things". Izuku pulled out two guns and opened fire. Despite the seemingly random way in which he shot Gran Torino could tell he was being herded. The final shot was made the only option of escape for Gran Torino was covered by his other gun. But instead of the crack of a bullet there was just a dull clicking sound. Izuku looked at his gun and sighed "This is my twelve round not my fifteen, dammit Kurogiri".

Gran Torino slammed Izuku's chest breaking a rib and dislocating his shoulder. However despite that Izuku gripped Torino's throat with his still working arm and flexed his ring finger spraying tear gas into the old mans face. He then slammed the elderly hero into the wall head first.

Sliding down the wall he looked at the hero killer and saw him dead blood loss and punctured organs having finished him off. Izuku sighed and called Shigaraki "Hay I need a portal, not directly on me I have some cargo I've got to take through it". He sent him his location and the prepared to give himself first aid as best he could with one arm.

However just as he began several heroes turned the corner rushing into the alleyway. Izuku grabbed the small old hero by the collar and threw himself through a half formed portal just barely dodging the fire.

Landing in the middle of the bar he gave a bloody grin "Hiii guuuyyysss". Shigaraki went to help him but All for One spoke. "That is Gran Torino, Kurogiri send him to me I will heal him and give him a reward for taking down that pest, be sure to send the rat my way to".

With a nod Kurogiri opened a portal once more, landing Izuku in All for Ones office. All for One turned off the camera to the bar and stood from his chair. The king of crime reached out and stroked his head with a glowing hand healing all his wounds instantly. "Izuku you have done well without a quirk, despite me offering one to you several times you have refused...however". All for Ones hand clasped down on Izuku's freshly healed shoulder and Gran Torino's head. "This time you will have no such choice".

Hay I think that wraps this story up nicely for now. All for One is a bit of a dick to his well pawns if we're being honest and Izuku is a very useful pawn but he's still a pawn so I think if All for One saw a chance to hurt All Might even a little bit he would take it. And this is quite similar to Shigaraki being Nana Shimura's son its just that Torino doesn't have kids so this is the most significant thing All for One could take from him to hurt All Might with.
