Izuku and the others were all watching Katsuki fight Tokoyami and the fight was clearly in Katsuki's favor given his quirk and Tokoyami's weakness to light.

Eri was sitting in Izuku's lap munching on a apple while her papa was subconsciously putting her hair in a braid for her.

The match went on for 2 more minutes before Katsuki knocked him out of the ring "learn to make up for your weaknesses then come and fight me for real".

Tokoyami got a small smile on his face and stood up "very well and next time I'll show you the power of darkness".

"I'm looking forward to it" said Katsuki before he put his hands in his pockets and walked away.

"WILL IZUKU SHIMURA AND TENYA IIDA PLEASE COME TO THE RING!!!" Yelled Present Mic.

"Welp looks like I have to go, cheer me on ok snowball" said Izuku putting her down in her seat.

"You got it papa!" Said Eri raising her fist with a smile on her face.

Izuku smiled and walked away to head to the battle ring.

"Hey girls I got a great idea how to cheer Izu on!" Said Mina standing up with a massive mischievous grin.

Shoka who just came back from the medical ward raised a eyebrow while she was playing with some of her red hair.

"Oooh tell me, tell me, tell me!" Said Himiko bouncing up and down in excitement.

Mina's eyes landed on Momo as she grinned "hey Momo were gonna need your quirk?".

Momo looked confused before she looked concerned giving the glint in her eyes.

"Also get Mei!" Said Mina.

"Whatcha girls doing?" Said a new voice.

They all looked behind them and saw a girl with long periwinkle blue hair standing behind them with a curious gaze.

"We were gonna cheer Izuku on and we need Momo's help" said Himiko.

"Can I help?" Said Eri wanting to help cheer her papa on.

"No Eri... Because I'm pretty sure whatever Mina's gonna do would make Izuku kill her if she let you" said Katsuki.

The entire class thought of an angry Izuku and that scared them... Then they thought of a angry Izuku in angry dad mode... They were pretty sure not even Kami could save them...

"ALRIGHT GIRLS LETS CHEER IZUKU ON!" Said Mina triumphantly.

"Oooh let me join!" Said Nejire since she was enjoying the fights that Izuku was having and was hoping to use this so she can talk to him sooner.

Mina led the charge with Himiko picking up a confused Momo and ran off with the other girls that liked him plus Nejire close behind.

They were running down the hall when they bumped into Kendo.

"Oh sorry Kendo.. wait perfect your coming with us!" Said Mina.

"Huh? What why?" Said Kendo before Mina grabbed her dragging her with them "WAIT I DIDN'T AGREE TO ANYTHING!!!".

Izuku and Iida were standing before one another and Izuku noticed that Iida looked different, he was sweating profusely but only on his face and it was beat red. With him also panting as if he was exhausted from doing something extremely taxing.

"ALRIGHT LADIES AND GENTLEMAN TODAYS LAST SEMI FINAL ROUND IS BETWEEN IZUKU SHIMURA AND TENYA IIDA!!!" Yelled Present Mic hyping the crowed up.

"NOW LE- WOAH WHAT ARE THE 1A GIRLS AND HADO ALONG WITH 1B'S CLASS PRESIDENT DOING!?".

Izuku was confused but then turned and looked and his entire face went beat red and his quirk malfunctioned and activated covering his whole body in flames.

Most of the girls in 1A were wearing cheerleader outfits along with Mei and Kendo and a girl Izuku recognized as Nejire chan who worked for Ryukyu.

"GO IZUKU!" Yelled most of the girls, the only ones who didn't were Kendo and Shoka with the former covering her face to hide her blush while Shoka stood frozen not knowing what to do.

"Izuku.. I think I know what your secret quirk is.. attracting hot woman.." said Fawkes.

Izuku was still frozen with his brain not being able to handle seeing all those girls in cheerleader outfits.

"Ahem... ANYWAYS ARE BOTH FIGHTERS READY!!!".

Iida and Izuku looked at each other with Iida forming a grin that belonged on a psychopath.

"AND BEGIN!!!".

The second he said that Iida blitzed forward with his leg only coming inches away from Izuku's head with enough force to rip it off.

"He's trying to kill me!" Thought Izuku as he grabbed Iida's leg and used his own momentum to throw him across the ring.

"YoU wOn'T sTeAl HeR fRoM mE!!" Said Iida with his voice sounding broken and unstable.

Izuku charged at him to try and hit him but faster than he could react this time Iida appeared before him and did an axe kick to his shoulder cracking the collar bone. He then reached forward grabbing Izuku's jacket and started to beat his face in with his fist.

"Hellscape!" Said Izuku as his whole body exploded in flames making Iida jump back holding his hand in pain seeing burns from the blue flames. "Flesh vs 3000° flames.. I think the answer is obvious who will win".

"NO I WILL BEAT YOU!!!" Said Iida as the exhaust pipes on his legs glowed and smoke blasted out of them "RECIPRO BURST!!".

"One for all 10%!".

Izuku watched Iida's leg move in slow motion and countered with his own leg and both of them slammed into each other with Iida feeling his bones cracks. He then reared his fist back feeling One for all build up in his arm and he threw his punch to Iida who blocked it with his arms to take the damage. All it did was soften the blow to his chest but left both his arms broken.

Iida fell to the ground in pain and tried to get up but his body was a mess from all those blows.

"Tenya Iida is unable to f-""NO I CAN STILL FIGHT!!!".

Everyone looked as he forced himself off the ground and had a look of nothing but pure hatred and this whole time Izuku was glaring at him as well. Except he was keeping his anger under control which was quickly diminishing as this fight continued.

"I WILL DEFEAT YOU AND SHE WILL BELONG TO ME!! YOU CAN'T HAVE HER NOR DESERVE HER!!!".

Everyone in the crowed looked confused on what he was talking about.

"She isn't your to take or keep, she's her own person and can make her own choices and you should respect her decision" said Izuku neutrally.

"NO IT'S BECAUSE YOU TOOK HER FROM ME!!! IF YOU DIDN'T INTERRUPT US THEN I COULD HAVE HAD MY WAY WITH HER!!".

The crowd looked disgusted and horrified that a UA student who was also the son and brother of three famous heroes was like this.

Ochako subconsciously took a couple steps back and Shoka stood infront of her along with the other girls showing they wouldn't let him get near her.

As for Izuku his anger was starting to boil over and his flames were getting hotter reaching well over 6000° at this point and with his anger rising black wisps of fire were seen.

Midnight who had to walk back 30 feet with Cementoss building a wall to shield them from the heat.

"She'd be mine once I got rid of you and gave that little white haired brat to those people you sto-".

*BOOOOOOOOOM*

Iida wasn't able to finish his sentence as a fist covered in black flames was slammed into his chest and was sent through the arena wall and the entire stadium where he then slammed into a building near the stadium on the other side of the road.

"DON'T YOU EVER MENTION GIVING MY DAUGHTER TO THOSE MONSTERS AGAIN!!!!" Screamed Izuku as black flames appeared as horns on top of his head. Making him look like a demon with blue flames dancing around him and the sheer heat of the fire was melting the very area around him with the entire stadium feeling it.

Midnight took a couple steps back in fear from the sheer anger and hatred rolling off Izuku and was scared that he'd snap at her.

"Holy fudge Izuku is angry.." said Katsuki terrified while trying to keep Eri calm.

"P-papa calm down!" Said Eri standing up and yelling to him.

Luckily Izuku heard her voice and was able to reign his anger in with his flames disappearing and he took a couple deep breaths.

"I-izuku Shimura wins.." said Midnight.

The entire stadium slowly started to clap before some of them started cheering.

Izuku finally got his anger under control and walked away already seeing the medical bots racing to Iida to help him. Not that he really cared for his state right now over what he said about Ochako and Eri.

___

He slumped down on the ground leaning his back against the wall of the hallway and sighed.

"I let my anger get the best of me...".

"Yes, yes you did, but considering the scenario it's understandable why you did get angry and I'm sure the staff will understand".

"Thanks Fawkes..".

"Also I must tell you that with you using the flames of hell he'll be permanently scared and there's nothing but doctors could do to heal the damage" said Fawkes.

"What do you mean?".

"The body is made of 3 things. The mind, the soul, and finally the body. With you using the flames of hell you destroyed a part of his soul which will never heal".

"Wait so you mean?".

"Yes, the flames of hell have left a scar on him and nothing can heal it, along with that villain Shigaraki. Nothing he or anyone else can do will ever bring his hand back because that part of his soul was forever destroyed".

"Papa/Izuku/Shimura!".

Izuku looked over and saw all his friends and Eri running to him with Eri quickly hugging him making him smile and rub her head.

"Are you ok Papa?" Said Eri looking up at him.

"Hehe don't worry I'm fine, I just let my anger get the best of me" said Izuku kissing her horn making her smile.

"I can't believe Iida would say all that on live TV.." said Momo bringing her hand to her chin in thought "plus he seemed sick in the head".

"He was" said Izuku "I think he was also on something..".

"What do you mean?" Said Himiko.

"His face was red and sweating profusely but the rest of his body wasn't... Not only that but his quirkseemedsomuchstrongerthanitnormallyis" said Izuku breaking out into a mutter storm.

"I think your right papa hisattackswerereallyfastandscary" said Eri breaking into a mutter storm as well.

Everyone watched as the father daughter duo were muttering and kanjis were piling up on the ground.

"Are you certain Eri isn't Shimura's secret love child?" Said Shoka looking at Ochako, Himiko, and Mei.

"Well..." Said the three who then saw both Izuku and Eri pull out notepads and started scribbling "...ok now we're not sure...".

Both of them stopped and looked at the others and spoke simultaneously "did you say something?".

"We need to ask recovery Girl to do a blood test on these two..." Thought everyone.

____

While that was happening Iida was laying on the medical bed in the infirmary while having quirk suppressant cuffs placed on him. His body was badly damaged and was reacting badly to the withdrawal of trigger.

"Yes I did a blood test and he came back positive for trigger... This boy was very close to overdosing on them" said Recovery Girl. "Not only that but when I healed him one injury wouldn't heal no matter what I did".

Everyone looked at Iida's chest seeing a burn on it that looked like it was rotting but wasn't at the same time.

"I don't know what Izuku did but nothing I do can heal him. Also I found a note in his pocket that gave him instructions where to... Deliver Eri for his money and more trigger..." Said Recovery Girl.

Aizawa's eyes narrowed as he looked at Iida with a glare that could give All for one a run for his money.

___

Somewhere in Japan said man felt a tick mark form on his head and that someone was challenging for a title he held great pride in.

___

"Not only that but from what izuku told me, he even tried to make advances on young Uraraka" said All Might wishing he could personally ring Iida's neck.

"I want him expelled and arrested for using an illegal drug" said Aizawa.

"Done" said Nezu appearing out of know where while holding a cup of tea and had a dark grin on his face "also we'll need a new student to replace him... Hmm I'm sure me or the readers will come up with an idea who to add".

The staff in the room screamed in fear since Nezu simply defied logic at every single turn.

Xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

"ALRIGHT NOW WE CAN BEGIN THE FINALS!!!!!!! WITH OUR LAST TWO CONTESTANTS IZUKU SHIMURA AND KATSUKI BAKUGO!!!".

Both of them walked out of the entrances and stood in the fighting ring but before they could begin the girls once again started cheering for Izuku.

"Your one lucky bastard getting a bunch of girls going after you, you know that" said Katsuki smirking watching Izuku blush.

"Shut up...".

"DON'T FORGET PROTECTION IZUKU!!!" Yelled Nana from the stands.

"GRANDMA!!!".

Everyone broke out laughing watching poor Izuku wanting to die of sheer embarrassment of the situation.

"WHAT? UNLESS YOU WANNA MAKE ME A GREAT GRANDMA THEN GO AHEAD!!".

Izuku hid his face and was currently hoping god will kill him.

"I won't" said Nezu over the intercom.

"Hahahah I'm already an uncle Izuku I don't wanna have to watch even more of your kids" said Katsuki snickering.

"AHEM.. ANYWAYS ARE BOTH FIGHTERS READY!!!".

Izuku got over his embarrassment and looked at Katsuki with a look that promised pain.

"AND BEGIN!!!".

"INCINERATION/AP SHOT!!!".

Both attacks collided and negated each other creating a massive smoke screen.

Izuku used the smoke screen to his advantage and charged through it and grabbed Katsuki by his leg and spun him to throw him out but Katsuki countered by creating a flash bang.

Katsuki ended up getting flung away but quickly used his explosions to slow his fall and quickly released a huge one to stop moving.

"You've gotten faster Kacchan, a couple weeks ago that would have got you" said Izuku finally getting his sight back.

"Fuck yeah, I'm not gonna sit around letting you hog all the fun" said Katsuki.

Both of them grinned and charged back at each other with Izuku slamming his leg into Katsuki's side while he smashed a explosive punch on Izuku's face. They both reeled back but Izuku got back up first and lifted his hand and released a massive torrent of flames covering the area.

Katsuki managed to just create a explosion on time to fly back but now his hand was slightly burned.

"Eat this!!" Yelled Katsuki as he slammed his hands into the ground and released two massive explosions shattering the ground to create shrapnel "SHRAPNEL GRENADE!!".

Izuku smirked and created one of his flames wings and blocked the attack but once he lifted his wing he saw that Katsuki was gone.

In the corner of his eye he saw him but was too late to react to the punch to the face then the knee to his gut.

"IMPACT!" screamed Katsuki releasing a powerful but small explosion on Izuku's stomach which launched him backwards.

"Damn he's been getting better.. a lot better" thought Izuku.

"Flame dance!" Said Izuku as he swung his arms like a blade and two flaming tornados formed racing to Katsuki.

"What the fuck!?" Said Katsuki releasing explosions to get back.

Izuku smirked and snapped his fingers causing them both to explode covering the area in smoke and fire. Given the smoke Katsuki couldn't see anything Infront of him and before he could react a bolt of red and yellow lighting was seen and then a fist slammed into his face.

Katsuki rolled across the ring before he released a massive explosion launching him up in the air where he used explosions to stay airborne.

Izuku saw this and smiled before he created both his flame wings and flew up to greet him.

"Kacchan I think it's time we end this fight" said Izuku.

"I agree!".

Katsuki flew high into the sky so he can use his new super move while Izuku combined his flames and One for all together in his right fist.

"HOWITZER/NEW YORK".

Katsuki flew to the ground spinning and flipped to release the massive explosion while Izuku reared his fist back and started to throw the punch.

"IMPACT/FLAME SMASH!!!!".

Both attacks collided creating a massive explosion covering the entire ring in a thick black cloud of smoke.

"HOLY CRAP WHAT HAVE YOU BEEN TEACHING THEM ERASER!?!?" Yelled Present Mic covering his face from the explosion.

"Certainly not that" he said in a deadpanned voice.

Once the smoke cleared Izuku was standing tall but panting and had some cuts and bruises which he told Fawkes not to heal just in case.

On the other side Katsuki was standing but he was in much worse shape and could barely stand. Everyone watched as he forced his body to start walking towards Izuku.

"I... Am not.. d-" his eyes rolled into the back of his head and he face planted onto the ground unconscious.

"THE WINNER OF THE UA SPORTS FESTIVAL IS IZUKU SHIMURA!!!!!!".

Then entire stadium started screaming and cheering in happiness from one of the best sports festivals of their lives to this day.

Izuku smiled before he too passed out from exhaustion and not allowing his injuries to heal in fear people would figure out what his quirk could really do.
