It was the day of their work placement. Izuku had watched the news and heard about what happened to Iida's brother, Ingenium. Once they met up at the train station, Izuku warned Iida to be careful, since his work placement is in Hosu. Than he went on his train, to meet Carlos in a place near Hosu.

*time skip*
"So kid... Let's get started. But, I need to train you a bit more first."

"Sure.. But what?"

"I said that we were going to Hosu right? Well, since I specialize in what I like to call, alley villains, I need to improve your mobility in limited spaces. First things first, double no, triple your squats, and practice your wall jumping in that alley over there. And use these weighted clothes while your at it."

So that's what he did. For the next two days he trained his legs. Then the time came for them to go to Hosu. They were talking in the train to Hosu.

"Be careful, I forgot to tell you, we're looking for the Hero Killer."

"Wait, what!?" Izuku said in an alarmed but quiet tone.

"Don't worry, I've seen your improvement, let's say, it's guaranteed that we'll make it out alive, I'm not sure about getting out in one piece though."

Izuku's confidence went up slightly, but it was still an all time low, suddenly, a monster with wings smashed into the train. It was very similar to the Noumu creature, except thinner and with wings.

"Shit" Carlos said. "Look kid, how bout you go alley diving? I'll follow, here. Take this. *throws some device with a button at Izuku* Press the button if you need help, it'll send be your location to me. Now if you excuse me, I need to go kill this son of a bitch."

"Right" Izuku said before jumping out of the train with Carlos, except he went in a different direction. Then he remembered that Iida's work placement was near by. Since Stain's pattern was he would kill in alleyways, he looked in alleys far away from the more populated areas.

*Meanwhile*
Iida's POV
"Stain..." Iida said in a tone full of rage. "I promise, in the name of Ingenium... I WILL DEFEAT YOU!!" Then he charged at him. Suddenly, he stopped moving. He couldn't move. He was also bleeding.

"Shouldn't you be more focused on helping that guy?" Stain said while pointing to an injured pro hero named "Native". "Your too filled with rage that it blinded you from what you should've done. Your just like the rest, stained. The type of heroes that deserve to die!" Then he started to raise his sword. Then he began to charge at him. Suddenly, the pro hero Gunhead appeared along with a black and pink clothed heroine with her.

"Iida-kun!" The heroine said while rushing to his aid.

"Uraraka? N-no.... This isn't your problem. Go! Leave!"

Suddenly, Gunhead fell on the ground. He couldn't move either. He too was bleeding. Then Stain was raising his sword and prepared to charge at Uraraka. Before the blade could touch her, she heard someone shout

"DONT TOUCH HER! SUPERMAN PUNCH!!!"

Suddenly, from out of nowhere, a hero clothed and green punched Stain in the face, sending the villain flying back.

"Deku?"
