Shinra's Backstory & Shinra Vs Rekka From Fire force mashup

My Fire Force

"Oh, this is so exciting." Hagakure giggled, bouncing in her seat.

"Why does it say 'Fire Force?'" Todoroki asked confused.

"why is there a title? I thought this was showing us alternate universe, not a tv show." Mina added.

"Settle in it about to start."

"Bu-"

"Ok, it starting."

The screen flickers on to reveal three people, Izuku, and Inko who cuddles a baby in her arm while standing on a small hill.

"Mom, I'm going to be a superhero, and keep both you and Sho safe." Izuku declares.

"So," Tokoyami said, "This hero thing runs deep into other multi-verses, huh?"

"I'm honestly impressed. It didn't know what I wanted when I was a kid." Uraraka said, scratching her cheek.

"AWWWW, tiny Midoriya is so adorable." Mina chimes in from behind them. Shouts of agreement rang out from the crowd, mostly the girls in the audience.

Mineta said, "Wow, Midoriya mom is hot."

"Try anything and I will fucking kill you," Bakugo said with a growl. Mineta flinches and shuts up at the blond bomber threat.

"Bakugou, language!" Iida huffed, glaring at the blond.

Grass drifts pass the screen, Inko grasping her hands and responded, she smiled. "That's so cool." Little Deku smiled back with sharp teeth.

"Wait... does Midoriya have a brother by chance?" Ojiro wondered out loud, allowing everyone to hear him.

Naturally, this got them all thinking.

"A brother?" Uraraka questioned in surprise before she looked back at the baby on the screen. 'I don't think Deku has a brother, but then again I never asked.'

"Hey, Bakugou, do you know if Midoriya has a brother?" said Mina.

Bakugou looked away, "I have no fucking idea raccoon's eyes?" replied Bakugou.

"But you and Deku are childhood friends, right?"

"So, does that matter?" Bakugou shrugged.

"Aw, don't be like that Bakubro," Kirishima said lending on Bakugou's shoulder.

"Don't call me that shitty hair," Bakugou grumbled, pushing Kirishima off before sighing. "No Deku doesn't have a brother."

Mei remained quiet as the others eventually looked back at the screen to the other world to see what will happen next.

A moment later, Rekka took over the scene, yelling "Die now, Yaoyorozu!"

"Who the hell is this?" Jiro growled, wondering why this man was yelling Momo's name.

"Jiro! Watch your language!" Iida chastised as he chopped his arm in her direction.

"Come on, bro, now really not the time." Kirishima laughed nervously. Right now, a random man threatened their classmate.

"Wait what about little Midoriya!" Mina cries.

The screen rapidly pulled out, "Stop, Lieutenant Rekka..." Momo begged. She was almost unrecognizable. Her cheeks swollen, blood flowing through her dried lips, her face still bears congealed blood and her clothes an utter mess. She raises her hand to defend herself.

A few like Shoji and Tokoyami looked over at their classmate face before they looked back at the screen showing the other world. What in the world happened to the other Momo?

"That's... that's me." Momo managed to get out.

"Momo?" Koda asked, noticing how quiet and scared she was sounding right now.

"Please... someone interferes!" Hagakure exclaimed, hoping that someone would break into the room, grab Momo and get her away from that man!

Everyone else gritted their teeth at the sight of the alternate timeline. Where the heck were they? Shouldn't they be rescuing her?!

Rekka hand light on fire as he swings down. It switches to Momo's lips and in an audible voice called out. "Help me." Tears were filling up in her eyes as she looks up into the distant sky.

"I know that isn't you, but I wish you weren't there," Jiro said.

Momo blinked, turning her head slightly towards Jiro as Koda hand came to cover her own "Are you okay?" Koda asked worriedly. "It must feel weird watching another you get hurt?"

Finding her voice, she muttered, "Don't worry." She forces a smile, "If this is going where I think it going then Midoriya should show up to save me."

A moment later, Izuku clouded in shadow in an orange suit fall out of the sky. His eyes appear to glow as flame flow from his feet, spreading like wings.

"Deku!" Ochako said, seeing their friend relief surged in most of the viewers.

"Wait, why does he look so sinister?!" Tenya said, shocked at his friend looking so evil.

"What's with that outfit? He looks like a convict in those." Kirishima said.

"Yeah... You assume he's done something and got arrested?" Tsuyu asked.

"Why's he so skinny, where'd all his muscles go?" Mina asked.

"Lack of training?"

"Probably under his clothes" Ojiro clarified having seen the teen's body and knows he's a lot buffer than he looks.

Izuku stomps his feet right on Rekka's face. He continues to grind his foot as Rekka resist before he gives out crushes under Deku feet as blazing explosion full the screen that sent ashes everywhere.

Momo shielding herself from the ashes. She watches Izuku over the older male, glaring down at him, a shadow cast over his eyes.

"Woah, that was so manly," Kirishima said, impressed by his entrance.

"I hope my entrance is as cool as this!" Mina said

The shadow fades from his eyes as he travels over to Momo. A nervous grin spreading across his face. "Are you okay, Yaoyorozu?"

Momo eyes widen wet with tears before she shakes her head. Tears running down her face with each stifled sob. Izuku smiled as the dust disperses, revealing a silhouette with a glowing star standing behind Izuku.

"My stars!" Rekka punches Izuku, sending him soaring past Momo as she exclaimed.

"Midoriya!"

Izuku shifts slightly on the chair.

A few hisses rang through the room. "Ouch." Sero rubbed his face.

Izuku active his Ignition setting his feet ablaze with enough force to twist in mid-air, landing on his feet facing Rekka, while sliding backward. He stumbles a bit, but recovers his balance just as fast.

"Hoshimiya Rekka, you're the culprit, aren't you?" Izuku demanded.

"Do not interfere!" Rekka dashes right towards Izuku and punches him right in the stomach, very hard. "Star Fist Jab!" Shooting him flying sky-high, coughing out saliva mixed with blood.

Sero cringed at this." Oh, that's got to hurt."

Izuku twitched.

"Hey, can Midoriya feel pain?" Momo said worriedly. "I mean for a moment it looks like he was in pain when other Midoriya got a punch."

"Yeah, I notice it too," Shoji commented.

"The machine provides the person who sleeps in here to experience whatever multi-verse we're watching as if they were there." Hatsume answer.

Momo, Bakugou, and Deku crew just gave her dull looks, while everyone else had a confused look.

Tsuyu put her finger towards her face with a tilt. "So, basically they can feel everything that is going on,"

"Yes, and no. It complicated. Have you ever had a dream that was so intense that you wake up kicking or punching or have someone fake punch you so that you blink against your will."

A few nods their head while just waiting for her to get to the point.

"Well, it like that Midroyia isn't feeling what happening. Instead, his body is acting through pure instinct."

The class looks a little less worried than they had before.

"So he'll be fine?" Uraraka asked.

"Yes, other than an aching body for seating so long he should be fine."

"I bet from any alternate world Midoriya is the most likely to gets injured the most," Sero joked.

"Agree. I only fought him once, and he was reckless in that fight." Shoto commented from where he was sitting.

"Deku..." Ochako muttered as she and Tenya glance at their best friend in concern.

Landing on his back, Rekka runs towards Izuku once more, sparing him no time to gain his balance. Izuku plants both hands on the floor, swinging his legs at Rekka who blocks with his hand pushes both back sightly. The momentum allows him to spin back around to jump in the air, knee Rekka in the face.

"Keep fighting, Deku!" Uraraka encouraged.

"Why is Midroyia fighting them alone?" Tsuyu asked worriedly.

"Is he breakdancing!" Mina shouts excitedly. If this Midroyia could break-dance than that meant their Midroyia could. Finally, she could have a dance partner.

Rekka recovers and punching him right in the stomach yet Deku counter with the deadly speed of a cobra. His right leg snapped behind Rekka's head before pulling him to the ground with him. Deku holds forearm, positioning his legs over Rekka's neck and the other over his waist to lock them in place, pulling the arm towards Izuku in a straight armbar to prevent Rekka from escaping. He set his legs ablaze and burning Rekka's face.

"This is so amazing," Hagakure said while they all stared in awe.

"Hoshimiya Rekka! Now that the hero, Catch-the-Artificial-Infernal-Maker man is here, there's nowhere for you to retreat!" Izuku declared.

Bakugou snorted.

"Yes, Bakubro, we know you hate Deku," Kirishima said from where he was sitting.

"I didn't say a fucking thing." Bakugou retorted. "And I have some level of..." he mumbles the last sentence.

"What."

"I said I have..."

"Can you say that again?"

"I SAID SHUT THE FUCK UP SHITTY HAIR!"

Rekka set his fist near Izuku faces aflame, escaping from his arms lock and punch him right in the face. "My stars!" Raising his arm again, he shouts. "I don't need to retreat! I only ever move forward!" Setting his fist ablaze, he punches Izuku, the ground bursting apart, releasing flames that consume the screen.

"IZUKU/MIDORIYA/DEKU!"

Out of the flames, the lower half of a woman's face wearing reddish pink lipstick devours the flames with an echoing "Devil!" It transitions to the back of Izuku's head, as he holds the hands of an older man. It shifts display three other. "Of course, I'm not going to take in such a dangerous child!" The old woman expresses in disgusted at the idea.

They shot looks of disgust at the TV.

Uraraka couldn't help but feel upset and angry at the grandmother's attitude at Izuku.

"Wow, what a rude lady" Hagakure said, not happy at the woman's attitude towards Izuku.

"Don't tell us that this lady also a family member of our Deku."

"I guess prejudice exists in all realms," Tokoyami said bitterly.

"Now, grandmother, you shouldn't say that in front of your grandson." One man defends.

"Grandson?" She opposes. "Do you know what that boy has done? And still... And still..." Shifting to show Izuku eyes glowing as he grins unnaturally.

"What a face to make for you to make!" She presents.

"That's hella creepy," Denki muttered. Mina nodded fervently. Todoroki focused intensely on the side.

As the smoke cleared, showed Deku hold Rekka fist. "Then I'm the keep-You-from-moving-backward-or-forward man!" His Ignition thrusts him forward giving him the momentum he needs to roll in a circular path on the floor twirling his legs in a V-shape through the air to kicks Rekka off him. But Rekka flips over and uses the momentum to slow himself down, lifting his head to glare at the Izuku.

"Midoriya fighting toe-to-toe against Lieutenant Rekka..." Momo murmured in awe.

"He's good,"

"This is so cool!"

"Hmph, I bet I could take him on!" Bakugou boasted.

"I will not allow anyone to interfere with our evangelism!" Rekka snarled.

Izuku sets his feet ablaze and grins at Rekka, a shadow crossing over his eyes except for his glowing green eyes. "Shut up, you hot-blooded son of a bitch." Izuku spat.

"Oh, no trouble for me. It just means one more dead body." Rekka retorted with a smirk. A shadow crosses over half his eyes leaving a radiating star while the other glows red. His flaming fist flourishing around him, giving him a tail-like appendage.

His eyes slide over to the side and see the Infernal Insect contained inside the bottle are reacting to one of their flames. He moves the bottle at Izuku direction, and the insect goes nuts.

"It's reacting to Izuku Midoriya flames. I get it. It's trying to go back to the flames." Rekka's face splits into a menacing grin, "Alright! This is my lucky day! So this is where you are the third person the Evangelist is searching for, The undefiled flame, the Adolla Burst!"

"Adolla Burst?" Izuku muttered.

"Who's the Evangelist?" Ojiro asked.

"A cult that wants to watch the world burn," Mei answered subconsciously.

"So informative," Ojiro muttered. "Wait, I thought you said you did not understand what was going on!?"

"Just a guess."

"What we who serve under the Evangelist have been seeking. That which can only be borne by the spawn of the great Sol-the sacred flame that will lead mankind! The pure, unadulterated flame. For a long time, I have been lighting pilot lights in children, in search of someone compatible, but imagine, finding someone right here!"

The preaching got the frowns and eye-rolls it deserved.

Uraraka frowned. "Oh, shut up already."

"Midoriya has a thing about fighting crazy people, doesn't he?" Shoto asked dryly.

Fumikage raised a brow (does he have an eyebrow?). "What makes you say they are crazy?"

"If they are harming people, they are crazy," Shoto said.

"In children, you say?" Izuku uttered as the screen cut to three different scenes, a hand on fire, in front of stained-glass then to two blurry figures, one who looks like Mei in nun outfits-watching fire blazed everywhere.

Hatsume stops the video.

"Seriously?!" Bakugou screamed furiously. "You're going to stop right here! What the fuck are you doing, Goggles!"

"Goggles," Mei repeats, but she still stares at the smaller screen in front of her. Not acknowledging Bakugou as her finger glide across the keyboard faster than their eyes could keep up with.

"Bakugou you don't need to be rude Ribbit." Tsuyu stated.

"Oh, fuck off frog legs!"

"What are you doing Hatsume?" Momo asked.

She turns to Momo for a moment before pressing a few more buttons. "Sorry just checking something, I'm done now."

Last is a house burning, before transitions to the bedroom that now embraces in amber light. Little Deku on his bed watching the fire rage in front of him.

"Mom... Sho..." Izuku called out, as though reanimated to life by his words. A horrible screech full the room, Inko took a small step forward between the flames and lifted an arm to his direction.

Koda made a horrified, choking noise. Momo's hands flew up to cover her mouth, and Mina shook her head.

She moaned, a ghost of a cry that sounded more of a whimper than a zombie moan. No longer on his bed, he stares In horror at his mom being burned alive. "Izuku!" She shouts, "Hurry and get out of here! Hurry!"

Tsuyu put a hand over her mouth, squeezing her eyes shut at the sounds of burning flesh. Shoji suppressed a gag, and Denki turned slightly green.

"Mom..." It shifts to a closeup of little Deku face, tears streaming down in his green eyes.

Nobody said anything.

'That must be so terrifying.' Jiro thought somberly.

"Exactly how many people have you turned into Infernals?" Izuku's words come out as a snarl, glaring venomously at the man responsible for ruining many lives just for the sake of this 'Evangelist's' goal.

"How many people do you think he killed?" Kaminari wondered as the opening song began.

"I'd rather not know the answer to that," Iida said darkly. It wasn't something any of them needed to know about. It was best not to wonder.

Momo felt her heart grow heavy as she watched the scene flashing on the screen. 'So many lives cut short... for what?'

Shoto looked down at his hands, nails digging into his palms just hard enough to avoid drawing blood.

The charred remains of Izuku house stood in the pale morning light like a skeleton. By now the walls had long since crumbled and in their place stood thick beams of wood, blackened and charred from where the flames had licked at them. Black dust hung in the air as Izuku stands in the middle of his old house holding an older man dressed in thick uniforms hands.

In the distance, three shadows silhouetted dance on the ground. "The son, Izuku, was supposedly the cause of the fire."

"There weren't even any bones left from his little brother Sho."

"That's somewhat depressing," Denki whispered.

"Did they say he was a third-generation? They can shoot out flames, right?"

"Terrifying, isn't it?"

The screen zoom close to his face. 'It wasn't me.' He pleaded. The tears freely fall.

"Dude..." Kirishima said as they stare at Izuku, who is crying on screen.

"Damn Midoriya. He looked horrible." Sero commented.

"If I saw that I'd cry, too," Mineta muttered. "Creepy!"

"You sure that's him?" Hagakure said shocked. Whenever she saw the Midoriya, he looked so lively, even if he was not always happy. This boy who looked so lost and hopeless was not the boy that class 1a knew.

"I thought nothing could ever get him down like this," Aoyama commented, horror-struck. To him, Midoriya was someone always ready for a fight. There was always a fire in those determined eyes. Nothing ever beat him. That was the image that the boy had built and shown the class.

"I guess we have all forgotten." Tokoyami murmured, causing Aoyama to glance at him. "Midoriya always shows how strong he is. Rarely showing weakness so it understanably that we forgets that he still just a kid."

"It doesn't matter." Rekka dismissed, "They were trivial sacrifices so that we could achieve our goal." Rekka with a sinister smile. His eyes glow brightly.

"That twisted nervous smile..."

"It's so disgusting."

"He's a Devil."

A memory from when his mom wasn't on fire appeared -'Ever since that day, I haven't been able to smile genuinely.'- before switching back to Izuku who screams. "SCREW YOU!" His feet bursting into flames as he rockets into the sky. "You think you can get away with this?!"

Reeling his leg back for a charge, Rekka merely side-stepped him avoid his kick and then punch him in the face.

The punch sent him rolling across the ground before crashing into Momo. His face lands right into her breasts.

Everyone in the entire class eyes widens. This... this wasn't going where they think it was going, was it?

Momo's jaw dropped, her hand covering her eyes, as the color drained completely from her face.

'Yaoyorozu's ample yaoyoro-boobs!' Minoru Mineta said, "Izuku, damn it! I won't forgive you!"

"W-What are you doing, you sicko!?" Momo snapped. A furious blush overtakes her cheeks.

"S-Sorry!" He walks away from the embarrassing moment. "O-okay off I go."

Looking down, she notices her skirt gone. "Don't walk away with my skirt!" Her hand moved to cover herself. He looked confused as he brings his hand up only to see Momo's skirt in his hand.

"Star Fist Jab!" Rekka punches forward, launching a fireball at Deku, who quickly shields himself. But Momo wasn't so lucky, letting out a scream as Rekka throws his fiery punches repeatedly.

"Yaoyorozu!" Izuku exclaims. Peers over his shoulder, his eyes widened as he locked eyes with Momo, who barely dressed and now had fire cat ears, two forked tails. Tears were lining up in her yellow eyes as her bottom lip quivering.

Everyone -other than Mineta and Kaminari who blushed with hearts in their eyes.- turn away, unable to stare at the screen. While it had lightened the mood earlier, it became too much once they burn off her clothes.

"She looks-" Jiro interrupted Mineta, sticking one of her earphone jacks into his head and shocking him.

"Let us close this up right away!" Momo exclaim embarrassed that her counterpart ends up in that position.

Izuku looks at her dazzled before Rekka punches him. "My star!" He sent flying toward Momo, landing on her with a loud smooch to her cheek.

"Sorry! It's not like that! I didn't mean to!" Izuku rambled. She turned her head to the side to avert her gaze, but the sudden rosiness of her cheeks gave her away. Grabbing Izuku's shoulder and pulling him to his feet. Momo pushing her hand into his back towards Rekka.

"Enough already, just fight!"

"R-Right." He agrees, stiffens as he pushes forward. His smile was present as he nervously stared at her over his shoulders. Suddenly his eyes widen as she pushes against him.

"Please, Midoriya... Defeat Lieutenant Rekka." her voice was quieter now, less sure. She looked at Izuku back. At that moment, he pulled into an old memory.

"There. All done." Inko smiles as she watches Izuku examine the newly formed cape.

"All right!" Deku eyes shined as he smiled. "Now I can keep everyone safe!"

"My heart can't take this much cuteness!"

"God, he's so innocent." Hagakure shoulders shook as she giggled with Mina, a fist shoved over her mouth to stifle the sounds. "It's adorable."

"Damn you, Midoriya..." Minoru Mineta sobbed as he watched his female classmates gush over how adorable Midoriya is.

"Come on, man. I mean, it is cute..." Denki Kaminari sighed, rubbing his neck with his eyes closed.

"Kaminari, how could you!" Mineta screeched, turning to glare at the blond with tears streaming down his cheeks.

"What, I'm just calling it how I see it!" the Electrification-Quirk user defended, turning his own glare to the shorter boy.

"Will you idiots shut, the hell, up?!" Bakugou roared, small explosions lighting the air above his palms.

"Mom, look! Do I look like a hero?" Izuku strikes a hero pose. "Mm-hmm. Very cool." Her face flood with a smile and Deku laughs.

With his resolved and determination renewed, Midoriya walks forward, "Leave him to me. That why I'm here." his flames flow outwards of his feet.

"YEAH!"

"Here we go." Mina grinned excitedly. She was glad the depressing, emotional, and not to mention intrusive scenes were over.

"Show him who's the boss, Midoriya!" Sero exclaimed.

"Don't let him beat you, Midoriya!" Hagakure cheered on in support.

"Yeah! You can do it!" Kirishima joined in.

"You know he can't hear you?" Todoroki said, but Hagakure and Kirishima didn't listen.

'Rekka's and my firepowers are about the same, or mine is a bit lower. But where I do have him beat is with my feet... My mobility.' He examines the building he in, 'This building is an excellent place to capitalize on my mobility.' He looks back at Rekka, to glare. 'Time to put it to the test.'

"My stars..." Rekka chucks his light overcoat-like garment to the side and his entire fists coated in blazing bright flames, burning his long sleeves. "I will burn everything up with my hot arms! My stars!"

"Annoying piece of shit," Bakugo said loudly, breaking the reverent silence.

"That guy." Ojiro moaned pitifully. "I can only imagine what Deku will do to him."

"Don't let him defeat you!" Momo exclaimed.

'I was going to be a hero... and keep Mom and Sho safe.'

The flame of his feet spreads behind him, Izuku rockets himself straight at Rekka with a powerful kick, but he effortlessly blocks the kicks with his arm. So Izuku uses the force of the kick to jump to the nearby wall. "What awesome firepower. My knee is hot just by glancing off him," he said conflicted as he stares at his burnt pant legs.

Izuku let go of the window rail free-falling to Rekka who pulls back his fist with an arrogant smile, "I'll shoot you down!" But before he could do anything, Izuku lands right behind Rekka, swinging his leg across his face and sends him flying into the air.

'Mom... Sho... I'm sorry. I couldn't keep my promise.'

Izuku waste no time rockets himself straight at Rekka swirls around, using the momentum to kick off the arm that was shielding Rekka's face, and he connects his other leg right into Rekka's stomach than to his chin. Rekka glares at him, having withstood his kicks. "Star Fist Jab!" His flaming fist collided into Izuku.

"I'm getting dizzy," Denki groaned, putting his face in his hands.

'But I will keep another promise.'

Izuku flew away just in time. "I outmatch you in mobility!"

'Mom... Here I go.'

"You only have a single foothold," Izuku gains his footing on the ceiling.

Once again he was in memory, from when he was younger, Inko removing her hands off his shoulder. "There." She smiles.

"Off you go!"

"Urgh. That smile. It's still too bright!" Ashido said.

"Wow, there are a lot of flashbacks." Jiro comment.

Bakugou rolled his eyes. "Obviously, he trying to make it an emotional scene." He said, smirking.

"Or dramatic. Perhaps he has too many flashbacks." Denki suggested.

'Off I go!'

Izuku smiled before it switches to his younger self cape fluttering in the wind behind him back to his feet, bursting with fire that flutters as his cape did. Instantly he jumps back towards Rekka, with a spin resulting in a small explosion.

Everyone cheered for Izuku beating up Rekka.

"Go for it, Deku!" Ochaco cheered.

"Go Izuku!" Kirishima cheered.

"but for me, everything is a foothold!" As if he could hear them Izuku comes down with incredible speed as Rekka looks up in fear before putting up a block but Izuku breaks through Rekka block with a direct critical hit straight into Rekka's face. "My stars..."

Rekka crashes to the ground with Momo watching from the distance while a cloud of smoke fills the screen the scene ends.

"Hell yeah!" the class cheered, jumping in celebration.

"He did it!" Toru cheered as she hugged Momo, the cheeks squishing together.

"That was Magnifique!" Aoyama said. "It was dazzling!"

"Yeah, he was so manly," Kirishima said.

"Well, it time we do another one," Hatsume said.

A/N

Forgive me I know that I should have made a post sooner. I was just so tired and I also was trying to convince myself to stop being a baby and post it. So it here sorry if it didn't turn out the way you would have like it. I'll try to fix it later probably.
