I have read a fic like this somewhere in the depths of AO3 and I really loved it. Too bad I forgot the name so I'm making my own version.

"Tch! Fucking pansy!" Ah yes, starting the fic with a foul mouthed growl, Katsuki continued pursuing the villain, finally obtaining his license, he now has the permission to apprehend villains as a student. But he didn't expect the villain to counterattack.

"FUCKING DIEEEEEEEEEEEE!"

As he used his explosions to propel himself towards the running coward, he positioned himself for an angle of attack, but, the villain suddenly stepped back, turned towards him and delivered a strong palm strike to his stomach, which sent him flying backwards. "GUUUGH!" he grunted as he flew back at highspeeds, but if he can rely on anything aside from his beloved quirk, it was his toughness and tenacity, he had proven once that he is physically tougher than Kirishima without the redhead idiot using his hardening quirk by playing punchies with him during study breaks, he is one tough boy.

But as he reared his palms back to propel himself forward, his palms stopped producing explosion, much to his shock. Now I don't give a fuck how tough you are, one solid blow to the back of the head will knock out any human being, Katsuki was no exception as he lost conciousness after hitting a post in high speed.

"KACCHAN!" he heard that dumb voice before drifting away.

Izuku saw her childhood bully knocked out cold, knowing that she now has a choice of pursuing the villain or taking this ash blonde idiot back home to safety, without hesitation, she choose carrying Katsuki. She shook her head as she walked towards his pathetic figure.

Katsuki ignored the warnings about how the villain can permanently erase a quirk, basically Aizawa on steroids, opting on relying on his battle smarts. Izuku knows without a doubt that Katsuki is a hardened fighter. Sure, he is a dickhead but he can bite as hard as he bark. But that villain is just way out of his league and that he should have listened to the speaker's warning first. Sighing as she kneeled down and wrapped his arm around her, she stood up and carried him. Noting how muscular he had gotten and blushing at the thought 'No, Izuku... You're many things... A pervert is not one of them.' she told herself.

Approximately 7 hours later

"Ughhh..." Katsuki slowly opened his eyes and saw Toshinori and Recovery Girl looking at him with depressed expressions. "The hell are you guys looking at me like that?" he grumbled as he sat up from the bed. "Grrr! That fucker! Someone please tell me he died!" he growled with his usual angry self. "All Might! You pummeled him, right?!" he continued to ask after receiving no response.

"Ahh, Young Bakugou... I've got some sad news from you..." Toshinori rubbed the back of his skinny head.

Birds fly away as our angry hero screamed at the revelation of never being able to Michael Bay anything ever again. "NANI THE FUCK?!"

"It's true. Even my quirk can't bring yours back, you did listen at the speaker about that villain, right?" Recovery Girl said. Katsuki was lost for words, looking at his shaky hands. Toshinori patted his shoulder in an attempt to comfort him and decided to lecture him about how he shouldn't let this break him. Katsuki's world goes mute, he can't hear anything aside from his loud heartbeat. His quirk, his oh so awesome quirk, gone.

At this point he would have blamed Izuku, but it was his fault, which made this even more heartbreaking... Atleast for him, I'm enjoying myself lol.

The tool he will use to surpass All Might and be the best, gone. Just because some asshole decided to squirm. Tears emerged from his eyes. If only that villain stayed still, he would have annihilated him. The hell is he supposed to do now?

Subconciously, he hugged All Might tightly, surprising the retired legend as the healer heroine left the room. Katsuki lets himself bawl his eyes out in front of his idol. All Might smiled to comfort him, he knows what it feels like to lose his quirk after all.

'But it's such a shame that Young Bakugou lost his at such a young age.' the blonde man gently ruffled his hair. "I... Fuck!" he sobbed as he used Toshinori's shirt as a tissue. "I'm pathetic... It's all my fault! And... And..! I didn't even land a hit on that fucker!"

Izuku carefully opened the door after eavesdropping, the boy who treated her like she was dirt is now in such a pitiful state. Sure, she hated how he was so mean to her when all she wanted was to be his friend, but she remembered the times when he used to be so sweet and protective, maybe he started being an asshole to her because she said she doesn't wanna be a damsel in distress and that she wanted to be a hero instead, she was quirkless at the time for fuck's sake.

But she admired him, how tenacious he is, how he always ace everything and that when he said he is gonna do something, it's as good as done. After the fight in Ground Beta, it made her heart jump when he gave her his opinion about her Shoot Style, sure it's probably 4 sentence max with an average of 3 words per second but it's so refreshing to hear him talknormally for once and not scream his head off. She felt warm. And now seeing him like this, hurts her.

"FUCK OFF, DEKU! YOU'RE THE LAST PERSON I WANNA SEE RIGHT NOW!" his scream snapped her out of her thoughts. "A-Ahhh! Sorry! I was just..."

"No." they heard Toshinori speak. Toshinori wasn't a very good teacher, but he wisened up as time goes on, he knows that the two needed to talk since Midoriya was quirkless once and Bakugou is now quirkless. This is something that'll make them understand their feelings for eachother, and to mend their shitty friendship.

"Young Bakugou. I know this is going to hurt your pride, but I think you can learn something from Young Midoriya." the two students were silent, totally unexpected. "For she endured your state all her life, maybe... Maybe she can tell you how to keep your spirits up." he stood up and wiped a tear from Bakugou's shocked face. "Please behave, I have errands to do. This is a learning experience for the two of you." he said as he left the room.

Izuku was scared out of her wits. Yes, she is able match Katsuki in combat, well she was, now she can win effortlessly, but Katsuki intimidates her due to the years of bullying planting a seed of fear inside her very core. It was silent, too silent for her liking.

"Fucking Deku..." he grumbled under his breath, breaking the ice. Classic Kacchan. She thought. But she can't find the words, did her mentor just doomed her? Sentenced her to die through sheer awkwardness? But fortunately, Katsuki kept talking.

"Well? Aren't you gonna laugh? Fucking irony huh? Shitnerd." Katsuki taunted. "I'm not laughing, Kacchan."

"You should be."

"... But I won't."

"Fuck!" he cussed as he punched his pillow. "You're so useless! Can't even laugh when it's appropriate! I don't need your pity, stupid nerd!" he yelled. 'Then why are you so angsty?' she thought.

"All my life, I called you useless, a pathetic scrub who can't stand in the same ring as me! A pebble! Yet now... Now... You're the one who is looking down on me! Isn't this what you wanted?! You fuck?!" he screamed. "Oh shut up! Stop whining!" she snapped, interrupting his angsty rant. "You're right, you called me those mean things, and now karma serves you right, but..." she trailed off.

"But what?!"

"But I know that this shouldn't be enough to break you! You're Katsuki Bakugou! The boy next door who is too prideful to acknowledge that he can't win a fight, the aspiring hero who will do anything to win! I've always admired you for that... I'll always will. So please, Kacchan... Don't let this break you." she said sadly as she bowed her head hiding a blush. The pause made it worse for her. But after a few more second of silence, he spoke.

"You can say Katsuki all this time and you kept calling me that dumb cutesy retarded pet name!"

Izuku's eye twitched, after all that rousing speech, he cared more about that?! Sure, she can't say Katsuki when she was young so she calls her Kacchan but- ahh whatever, that's not important right now.

"Can't you see, De-" he paused, causing her to look at him.

Her orbs met his, he averted his gaze, which is so unlike him "I can't even call you that... I guess I'm the Deku now..." he solemly muttered. "N-No, Kacchan! Deku is the name of a hero! It's not useless, you're not useless... I don't know how but I'll help you!"

Having enough of his ex rival's nonsense, he threw a pillow at her face and dashed out of the clinic.

"Ughh... Rude as always..." she sighed. She looked at the pillow and had this urge to sniff his scent. Yeah, she likes him. And yeah, she knows how pathetic it is.

She hugged the pillow and mumbled to herself "Maybe I should give him time? He'll get over it... I hope."
