After a long game of truth or dare, the big three and Midoriya acquainted themselves and got pretty close.

Mirio, having his back sore after Naruto running down the halls with the other three on his back asked: "So what now?"

Getting a piece of paper out from his bag, Izuku explained. "Well... number 2 is not really precise, it just says to send Nezu a text and roll with the events that's going to happen."

"I have a bad feeling about this." Amajiki shivered.

"Me too." Deku agreed before pressing send.

"Since when did you have Nezu's phone number?"

Hado popped out.

"Do you really want to know?"

...

"Good point." The big three agreed.

Suddenly, the speakers began:

...

"Well that's just great." The target sighed.

Then, all the students of UA got out of the classrooms to kiss Izuku. Hoards of students could be seen around the halls, using quirks to locate him.

The four students were now cornered in the halls with no seen exit.

With a nod, Mirio opened the window as Amajiki ate something and his arms became tentacles, blocking the students or knocking them out. Hado picked Izuku up and got to the window ledge, flying down with the other two boys followed suit.

"What the heck!"

Getting up, Mirio began to give orders. "I will be on offense duty, you guys switch to keep the cinnamon-roll pure. Remember, stay close. Let's head to deserted areas. Try and find a good hiding spot."

"Yes sir!" The other two responded as Izuku tried to get his head to stop spinning.

Now in a training field, a bunch of students arrived only to be defeated by Mirio.

After two hours of evading the school, the trio began to get tired. Now surrounded by all the students, Izuku had no choice but to use... that.

Izuku and toshinori (aka, All Might) were in the teachers lounge sipping tea. The small boy was called over by the hero during lunch to have a talk.

"So... All Might, what did you want to talk about?"

"Well my boy, as a hero in training, I see that you have trouble with combat oriented exercises." The blonde began.

"I agree, but Nezu, Snipe and Aizawa are both teaching me ways to defend myself and protect others through methods like martial arts and weaponry. I may not look it but I'm pretty buff."

"Yes but sometimes it may not be enough. But please don't be discouraged for I have a solution that would benefit us both."

Izuku looked up in confusion. "What would that mean?"

"I can give you my quirk!" The teacher stood up in All Might form. The inspirational moment was then ruined when All Might coughed blood and became Small Might again.

"Geez, are you All Right (pun😏) ? How many times must I tell you to take stuff easy? I may have restored hours of your time but not all of it yet. Don't push yourself in hero work cause your also a teacher. Wait... what did you mean by you can give me your quirk... is that a thing? Is that your 'mystery quirk'." The boy mumbled while healing him as mr Yagi simply smiled.

"Calm down my boy, I'm fine. Though I have began doing more teaching since I can stay in my form longer. I requested to teach more classes in order to help shape the futur heroes. Anyways, my quirk is called One for All... " he began to explain everything including All for One and the fact that it will boost ones quirk.

" With all due respect, why me. They are many contestants you could choose from?" The boy looked down.

"Because, you have a heart of gold my boy. You would do anything to help others and have already saved many." The hero smiled.

"I accept. Thank you sir, I won't let you down."

"GREAT!" He scanned Izuku and realised he may be strong enough to get One for All.

"Now... eat this!" All Might said while plucking a piece of hair.

The student deadpanned. Thus the training began.

"One for All, twenty percent full Cowling." Izuku muttered and dodging attacks.

"Mirio, take the third years. Amajiki, take the second years. I will take the first years and Hado, don't limit yourself to specific targets, use your quirk to wipe out students in mass. I can heal you but not restore your stamina."

"Got it!" The big three exclaimed.
