A/N: Sorry for the bad lighting and I attempted to quickly make a hero costume so I could be able to imagine it better in this chapter so I'll explain it a bit, since you have a quirk where chains shoot out of your flesh whatever part is not colored in in anyway is a uncovered area so that you can use your quirk. I think that is all so enjoy
"Everyone it is time for the trial of battle and I'm digging all of your styles!" All Might announces before looking at Izuku and letting out a slight chuckle so you roll your eyes in amusement because the similarity is broadly familiar
"Tetsutetsu! Wow uh your costume" Kirishima comments with a blush so you chuckle with slight embarrassment
"Heh yeah I had to reveal a lot of skin for my quirk... but it seems you've went the same approach even though your quirk didn't call for it" you tell him making him nod with a slight smile
"Well it seems we somewhat match" He chuckles as he runs his hand through his hair
"Young Tetsutetsu and young Kirishima! Please do not flirt when I'm giving instructions!" All Might reprimands, although he doesn't seem mad but it still has the two of you blushing
"Y-Yessir!" You guys yell, bowing in apology before he continues
"Well anyway this is a two on two team battle, well except there will be a two on three battle in the case of our extra student" All Might announces making you and Kirishima exchange looks of curiosity
"Aaand the best part is each team will either have a hero or villain personality to it!" All Might tells you and in all honesty you hope for villain cause it would be funny to go all out
"Plus this time there isn't robots to destroy so it is students versus students" All Might explains resulting in random questions from everyone that you can't even pick up on
"I can't hear you all at once" All Might announces seeming strained at the fact he couldn't hear anything
"Well anyway in this challenge the villains will be guarding a nuclear weapon while the heroes try to stop their nefarious schemes! If the heroes manage to capture the villains or make it to the nuclear core before time runs out they win and the same other wise other than the fact that the villains have to protect the nuclear core! Now we will draw lots!" All Might explains the plans before holding out a box to everyone so everyone draws and you quickly pick a card to see that it has an A
'YESS FRIENDS!!' You celebrate in your head as you realize that you are teammates with Ochako and Midoriya
"Now to see what teams are up first and on what side they are" All Might announces as he draws, team A is versed against team D, you are the heroes and they are the villains
"Team A is the team of heroes and team D is the villains!!" All Might shouts boisterously
'Oh no' is what goes through your head as you notice Bakugo's and Midoriya's expressions
"This scenario will have the villains in the building first and after five minutes the heroes will come in! Everyone else will watch on surveillance cameras. This will allow young Iida and Bakugo to enter the mindset of a villain and feel free to go all out without worries of injury! Though keep in mind if it goes all out we will have to cut this short." All Might tells all of you then moments later you are outside the building studying maps and waiting to be let in
"Good thing we have these maps even though we have to commit them to memory and All Might isn't trying to scare us with a punishment like Aizawa-sensei!! He is so nice!" Ochako exclaims as you study the map intensely trying to hide your worry, who would you help? Ochako or Midoriya? This is gonna be tough
"You both seem really worried" Ochako comments noticing Midoriya sweating bullets and you just frozen
"Sorry our opponents are Kacchan and Iida so I'm worried" Midoriya explains so you stop your map and look up at the sky
"I don't know who to help" you whisper feeling split in half cause your quirk can easily move the bomb so Ochako won't get sick but Midoriya will get hurt by Bakugo if you help her
"Help Uraraka" Midoriya tells you making you look at him then he flashes a signature hero's grin
"I need to face Bakugo" he tells you so you squeeze you fists tightly then nod with a smile
"Ok hero" you announce with a grin before holding out your fist and earning a fist bump
"You guys are turning into best friends!" Ochako squeals happily so you both grin at her
"Trial start!" Is shouted over an intercom making you and your friends run into the crumbling building
"Infiltration success" Ochako comments as the three of you enter the building through a window
"There are a lot of blind spots so let's be careful" Midoriya observes as you examine the room with him
The three of you travel through the building until BOOOOM! Midoriya knocks you and Ochako out of the way while you use chains to knock your enemy back
"Damn that hurt you bastard" Bakugo growls as he stands from the rubble where he was thrown by you rubbing blood from his lip
"Are you two ok?" Midoriya questions earning weak nods from you two, in all honesty you were so shook by how surprising the attack was
"Yes we are" you tell him because after a quick glance you could see that Ochako was shaken up but over all fine
"I thought so but I knew his priority would be me, so he can beat me up!" Midoriya announces his estimate so you clench your teeth because you forgot that this would be the case
"I'LL BLOW YOU AWAY! BUT IT WILL BE JUST SHORT OF THIS BEING INTERRUPTED!!" Bakugo screams crazily as he prepares to throw an explosion your way but Midoriya puts a stop to that by grabbing his arm to prepare to flip him
"You know what! Deku! Deku means something big to me! And it means that I will never give up!!" Midoriya roars as he flips Bakugo effortlessly before throwing you and Ochako a look, it's time to run
"Let's go!" You shout, grabbing your ally and running with her all the while ignoring a burn that made your back ache
"We will fight and win!!" You scream not knowing that you instantly amazed your classmates with your intense will
