"We may be 'The League of Villains', but we fight for a just cause. Will you join us Izuku?" All for One asked.

  Izuku stared up at All for One.

  *All for One, the worst supervillain to ever exist, the boogeyman that steals naughty children's quirks... He's real, and nobody knows it. The only mentions of him are in old stories about the boogeyman quirk stealer... But even then those stories were most likely written to show how terrifying a quirk stealing power could be... If I go with him I can find out what exactly is going on... I could be a hero, even if it's only once. But.. it'll still be worth it.*

  "I'll join your league." Izuku said.

  He grabbed Katsuki's arms, blowing them into nothing, their remains splattering across the floor. The boy screamed, falling back to sit on the floor.

  *Sorry Kacchan.. but you aren't nearly strong enough to help me. I'll tinker with your arms, strengthen the bones, improve blood flow and sweat production... You'll improve so much faster than before...*

  Izuku repaired Katsuki's arms, leaving with a visible smirk, but with a guilty heart.

  *Sorry for causing so much pain.. but it's for the greater good. All for One needs to be stopped, and you need to be strong enough to take on a Nomu yourself...*

  The girl's arm was grabbed by the Nomu now before her. Shigaraki reached for the frog girl once again. Izuku went to check if the hero Eraserhead was alive.

  The black haired, bloody man was alive, but barely conscious. Izuku reached out, disassembling and reassembling the man's body, fixing the most severe injuries. The man was out like a light when his body reformed.

  The doors burst open, and a loud voice bellowed out.

  "FEAR NOT. I AM HERE!"

   "I'm here." Uraraka said. "What do you want?"

  Izuku smirked slightly.

  "I just need a little blood.."

  Uraraka frowned, the pink sparks activating once again.

  "Blood? What for? What are you planning?" She asked.

  "The downfall of All for One." Izuku said, his expression turning deadly serious.

  The pink sparks disappeared. Her expression was a mask of shock.

  "W-what??" She asked.

  Izuku chuckled humorlesly.

  "Not what you were expecting huh? Yes, I'm actually one of the good guys. All for One is alive, and planning the downfall of society, starting with the death of All Might and any heroes he comes across." He said.

  Uraraka frowned.

  "You've hurt people. You attacked my classmates. You helped Shigaraki try to kill us." She said angrily.

  Izuku huffed.

  "Hurt? Yes. Attacked? Eh.. maybe. Helped Shigaraki try to kill you? Absoloutely not. I went to the USJ to keep your class alive. I blew up Ka- Bakugo's arms to remake them stronger than before. I healed Eraserhead, and improved his quirk by strengthening his eyes. I took Iida's blood to give a copy of his quirk to Ingenium Senior, to make the already powerful hero even stronger! Everything I do, I do for the greater good! I've accepted that some of what I do is wrong. Once All for One is taken care of, and the rest of the league is neutralised, I will willingly go to Tartarus prison! You can punch a hole through my chest with One for All once this is over if that's what it takes to get your help!" He said, his hand clutching at his chest.

  Uraraka stood at ease, her eyes wide.

  "You're.. really serious about this." She said.

  Izuku nodded wordlessly.

  The brunette sighed.

  "Why do you need my blood?" She asked.

  Izuku chuckled.

  "I'm glad you asked. It's to do with quirk factors and compatibility... You see, One for All has a secret I'm sure you haven't discovered..."
