Your pov]
Just another day at U.A. Regular classes and then hero training, excelling at both was easy not only since me and Momo would study a lot to try to keep ahead of each other but my father made sure that I knew all this from a young age, making it so I aced pretty much every test when growing up. As for acing training it's mostly the same thing as what I did growing up, other then today. The entire class changed into there hero outfits and got on a decked out coach bus, apparently here this is a regular school bus to them. Like usual I sit in the back of the bus and Immediately take my phone out looking through all the normal notifications, the seats around me being taken rather quickly, not to my surprise. After awhile of listening to everyone talk amongst themselves I decide to put on some music. Sliding my headphones over my ears I start to play one of the few songs I like. Keeping it so I could still hear if my name was brought up in conversation I began to close my eyes almost nodding off before someone shook me up. I quickly sat up and flung my headphones to my neck letting them play the song loud enough for anyone within earshot that was paying attention could hear. Quickly before the lyrics cycle around again I paused the song just in time for the bus to stop. Apparently I had fallen asleep for the majority of the ride missing out on any conversation I could have been in. I decide to leave my headphones on the bus so that I don't lose them or have them brake during training. Slipping my phone into my pocket I join the others and make our way to the stadium looking place where outside stood a hero in a space suit named 13. Once inside we were informed that this would be rescue training through various different disasters, glancing away from 13 towards the center of the stadium I witnessed what appeared to be a portal appear next to the fountain. With everyone distracted I mange to sneak away unnoticed towards the portal as large groups of street thugs make there way out, by the time Mr.Aizawa or anyone for that matter realized I was gone I was already being charged at.
Y/n:"Good grief villains never seem to learn do they." I said as one with a four arms quirk attacked me with a knife in each hand. Just as he was about to swing at me blue on black melted the knives to his hands and broke his arms at the elbow. The villain screamed in pain gathering everyone's attention. Mr. Aizawa quickly jumped down to hold them back as he kept yelling for me to leave with the other students, I just laughed his warnings away and continued to beat these guys, keeping them from attacking him from behind. We probably took down 15 maybe 20 villains before the 3 main ones decided to make themselves known. One seemed to be a purple mist, another had a bunch of severed hands on him and the last one looked like big bird but if he lost half of his skull and had painted himself black. Aizawa trying to defend me, when I clearly don't need it, Charged at them only for big bird to break his arm and for hand guy to slowly decay Aizawa's elbow. I quickly jump in and pull Aizawa by his not hurt hand away from them while blue on black punched them all in the face. The bird just stood there while mr decay scratched his neck and began mumbling something to the bird, and before I knew it big bird was charging at me. Blue on black got in its way and began to soak that thing in punches each one laced with enough radiation to melt straight through his skin. Sadly though it was no use as the bird seemed to be taking no damage whatsoever. It reeled back it's arm and swung forward, me and blue on black barely had enough time to dodge we land to the left of it and began to clash fists with it. I could tell this thing was stronger then blue on black by a small margin but blue on black was faster by the same margin. I use this to me advantage and have blue on black punch that thing in the face a couple times before knocking it away and firing at it with a radiation blast that immediately torched the surrounding area. I was about to continue the assault when I heard Izuku yell, turning around I see her, Tsu, and Mineta who looks water logged are right by the severed hand guy. I yell to get there attention and immediately blast them back with another radiation blast, I wasn't close enough to do anything more then push them back enough so Izuku wasn't killed. In doing so I let my guard down, and was punched in the back by big bird. I probably went through at least 3 buildings before being able to stop only cause of blue on black and some rebarb piercing through my legs and chest. I coughed up some blood before managing to push myself off the rebarb, collapsing on the ground I shakily attempt to stand as that monster roars at me. Then the guy that's all hands shows up next to the purple mist guy, they both looked at me as I laid on the ground pretending to be dead so I could buy myself some time. The two called off the birds attacks on me after determining I had died, they were half right. I wasn't dead but I was dying all three rebarbs had cut large groups of arteries and muscles in my body, forcing my self onto my back so I could look up at the sky for a bit. Looking to my left I see Tsu and Mineta running to me while Izuku was hauling ass towards the bird blood dripping from the corner of her lips.
Y/n:"Good grief." I said before propping myself against the wall breaking off the rebarb so I don't impale myself again.
Tsu and Mineta: "Y/n!" Both running faster then before charged right at me only for me to pass them with blue on black, the draft from blue on black spinning them around to face me, the bird and, Izuku. The bird was about to punch her in the face till I slid in between her and it's face, taking the punch sends the two of us flying back while blue on black starts to smash his skull in. We bounce off the pavement for a bit till finally we stop with her on top of me her head resting on my chest. She gets up bloodied and bruised but still able to move, with a massive blush on her face the backs up and checks my wounds, the three holes were rapidly dripping blood faster and faster, I cough up some teeth and blood that were sitting in my mouth now from that punch to the face, 4 teeth lost that's going to suck. I look over to blue on black who was man handling the bird with Allmight who arrived recently, with how he was talking to him he must have thought he was a random hero that just so happened to be here. The two were tag teaming the shit out of the bird, not giving it a chance to attack at all. With as much power as I could muster I told blue on black to soak the bird in radiation, all might punched it in the chest right afterwards sending it into the sky.
Y/n:"Blue on black!!!!" I yelled and he flew up to the bird before it left my range and held it in a bear hug that it was too weak to escape from"Atomic drop." A loud whistling could be heard as blue on black and the bird came crashing to the ground making a non lethal, to anyone that didn't have radiation on them, nuclear bomb that filled the USJ. The crater stopping just short of where me and Izuku were. Blue on black returned to my soul clearing the nuclear dust with him showing that in the crater there was no sign of it left in this world. All might then began to taunt the last two main villain's the hand guy kept scratching his neck while the purple mist tried to convince him to attack. The guy listens and as he was about to lunge at allmight I sent out blue on blacks arm and threw some rebarb at him hitting one of his hands off his body gaining his attention.
???: "You? But I thought you died, how could a mear child survive against my nomu!? "
Y/n:"I am not a mear child. My name is Y/n Joestar, with my ability I call Blue on Black I will be the Judge against all people like you." He turns to run towards me only to get shot in the hand. The purple mist quickly took himself and the hand guy away. Allmight hauled ass over to us as soon as he could turning into his scrawny less mighty form, at first he thought I would be shocked about that but not really, he got some other hero's to help get me to the paramedics outside, I pull my hat down over my face in embarrassment since I was supposed to be one of the strongest students in class 1-A and here I am getting carried to an ambulance by Cementos all cause of some damn rebarb. The entire way there my friends kept staring at me, Momo somehow convinced the medics to let her and three other people tag along to make sure I was ok, I wanted to say no but it was already decided and before I knew it I was on my way to the hospital with Momo, Izuku, Bakugo, and Todorki. Two out of the four having tears in there eyes, one kept looking at me with a sad look with tears threatening to show, Bakugo, and Todoroki held onto my wrist making sure I had a pulse and whispering for me to not die. I smiled lightly muttering my phrase before blacking out from blood loss.
Y/n:"Yare yare daze."
