Izuku stared at the behemoth of a man in front of him how has influenced his life so dramatically. 'OMG OMG it's All Might! I can't believe it! Wait should I ask for an autograph or should I..' before Izuku could finish his train of thought.
"Hell young man. Thank you for slowing down this villain and allowing me to catch up! Sorry I took so long, this city's sewer system is hard to navigate! I am sorry but I must contain this villain and be on my way." And with that Izuku was star struck with the way All Might was always working so valiantly and tirelessly. He had seen it on the news, the way he tried to spend as little amount of time with the press as of late. He wondered why?
"What's that my lord? You wish to know the secrets of this man in front of you? Your wish is my command!" And with that Izuku's white eye glowed.
"All for One today is the day I bring you to justice!" Announces All Might to the mysterious man facing him. "Come now let's bring this to an end!"
"Yes All Might let's!" And with that both charged at each other, a flurry of blows being traded between one another and still fighting. The man Izuku believed to be All for One took a massive leap away from All Might to suddenly start hitting him with lasers. While also vanishing and reappearing around All Might. He was having trouble trying to keep up with him.
For some reason then the man seems to slow down. "What are you doing All for One? Finnish me already!" Screams All Might in agony to his rival.
"You want it to end so badly so be it! One more blow each to decide our fates!" And with that the vision came to an end and the glow in Izuku's eye vanished.
"What was that?" Izuku wonders in pure awe at seeing the fight that befell his hero. Izuku is confused about the vision he just saw.
"What's wrong young man? What did you just see?" At these questions Izuku decides the best way forward is..
"All Might, who is One for All!" The million dollar question. The look on All Might's face was that of pure shock. In an instant he was in Izuku's face with his fist drawn back. Ready for a fight!
"How do you know that name young man?"
"I saw it in a vision just then. You both nearly killed each other!" The look of Izuku's face was of a scared child who didn't know he did something wrong. All Might saw this and retracted his arm.
"We need to talk young man."
On top of a roof All Might explains the history of All for One and the birth of One for All. He shows Izuku his injury and says about the final battle. Izuku takes all this information in an remembers it.
'I won't be able to sleep tonight.' Izuku thinks with a worried but interested face as All Might shows him his true form.
"Well I will be seeing you later Izuku Midoriya. It was nice talking to you." And with that the deflated version of All Might who's name he learned to be Toshinori Yagi.
"Man what a stressful day hopefully nothing ba…" before he can even finish his sentence he hears a load explosion from a little away. 'Wait if that's where I think it is then.' As the realisation hits Izuku he starts to sprint with all his might tithe source.
As he approaches he hears screams and a very familiar voice "get of me you..!" And as sudden as the voice starts it stops.
"Kacchan no!" Yells Izuku with fear and dread in his voice at the sight he sees. A building has been blown apart with rubble strewn across the street. People are pinned by it but from a quick glance around Izuku can see that no one appears to be dead. 'Well that's good at least.' Izuku thinks to himself. He sees Bakugo in the ruined building surrounded by slime? 'Wait that's the same villain that All Might captured? Did he escape somehow and if so where is he?' With a frantic look around Izuku sees no All Might true form or otherwise.
"Someone get this Jackass off me!"
Izuku hears Bakugou's scared plea for assistance, which he will most likely deny later down the line. 'I have to save Kacchan! But how?'
"Do you wish to save your friend young master?" This voice is, different it's not Kishi and not his own.
'Yes I wish to save Kacchan!' With the yell in his head Izuku is surrounded by a pitch black darkness which seems to swallow even light. His black eye seems to radiate the same glow. This frightens some witnesses as they think another villain as appeared. All of a sudden it seems to reach out to the slime villain.
"Wait it's you again. You stupid- wait what's going on? Ahhh…" then the moment his screams leave his mouth he disappears along with his screams of fear. Even the echoes that should have rung around the street are nowhere to be heard. The blackness around Izuku fads and he falls from where he was hovering unconscious.
