A/N: The other guild will consist of class 1B and a bunch of random thots with no names or personalities.

"My fighting spirit is red... Why? Because blood is red."

-I-AM-A-LINE-

Kirishima felt her chest burn as she fought herself to remain still, the sheer excitement only heightened by the approaching forces that materialized one after another in the distance. Unlike their own group, the 'enemy' was arranged in an almost uniform line as they approached in sync. They looked like toy soldiers, and Kirishima bit her lip as the urge to laugh built up in her chest. She couldn't help herself; they were as ragtag and varied in appearance as their own group, and it seemed so unfitting.

Kirishima glanced up to see Bakugou smirking alongside her and felt a sh*t-eating grin make its way onto her face. Finally, the second group had all arrived, and Kirishima noticed that their numbers more than doubled their own. Was that really one guild?

"Scared?" The blonde continued to smirk, this time at her. At first, the redhead didn't answer, and Bakugou's smirk fell slightly. He had been joking, but the blonde frowned as she shook beside him, eyes cast to the dirt.

His momentary worries were blown away when he finally caught sight of her face and the barely contained excitement that it held; the shaking translated to anticipation, and the blonde bared his teeth as he grinned alongside her.

The rest of their party, feeding off their leader's aura, followed him closely as he ventured forwards onto the soon-to-be battlefield with matched vigour.

"Hey Riot, stick back with us for now." Kaminari grinned, using her new name: "This part is between the big shots." Sero nodded alongside his companion, motioning towards the blonde as he made his way to the middle along with another man from the opposing side.

Bakugou stood face to face, or well, face to chin, with the towering leader of the 'B' guild. It had an actual name, but he couldn't be half-assed to remember it; all he knew was that they were always second best to his own, and so he would refer to them as such. Sekijiro Kan stood at a shocking 6 feet 4 with white hair and protruding fangs, a muscled brute of a man that had a reputation of his own.

Neither party said a word as the larger of the two extended his hand, a glowing red symbol etched into the palm. Bakugou stared down the beast with disdain as he extended his hand to meet Kan's and gripped it with unnecessary force, which was returned with matching strength.

"We are in agreement that the price will be the land upon which the battle is fought, with the victorious party claiming all rights of trade."

"If you think you can handle the loss," Bakugou grinned as the matching symbol on his palm faded to nothing, the contract binding. It was a precaution to make sure that the losing side didn't chicken out of the deal.

"I have always believed your arrogance will award you a suffering defeat one of these days, perhaps sooner than I had thought." By some invisible cue, both leapt backwards a few feet, and the battle began. Both guilds crossed the field to meet with a clashing force in the middle, with small fights breaking out across the expanse.

Kirishima had initially missed the cue but was quick to jump into the fray, ducking and weaving under the advances of unfamiliar faces, punishing a few along the way as she was finally able to put Bakugou's training into practice.

It was rather easy to locate the blonde, with his explosions radiating across the field and acting as a fiery beacon. However, while she had found him, it seemed it would be a difficult task to approach him as he had become the very centre of the battle. Bakugou himself was a prise; defeating him would award an unimaginable reputation, and everyone seemed to want a piece of him.

Kirishima grinned; perhaps it was time to show what she could really do.

With newfound resolve, her blood began to flow faster, and her skin prickled with a familiar sensation as it became harder and rougher. She had been practising this technique in secret for the last month, spending even downtime manipulating her physique, and finally, she had something to show for it.

While barely a quarter of her impenetrable scales had been removed, her skin had hardened to the strength of solid stone, a technique she would call 'Red Riot Unbreakable'.

With a battle cry of her own, Kirishima leapt deep into the blonde's seemingly impenetrable circle, breaking through opponent after opponent with sheer force. What a thrill it was to fight among humans! On the same feet as them, swinging fists and charging into a battle among their forces, what a feeling it was. Even more so knowing she was fighting for something or someone.

Kirishima wasn't sure how much time had passed or how many opponents she had defeated, but she eventually found herself side-by-side with Bakugou, much to his surprise. It seemed that she had worked her way up to the same level as he had and was placed as a priority. He should have known she would be quick to make herself known; she wasn't the type to be left behind.

She reflected a part of him in that way.

However, as the battle progressed, Kirishima found it harder and harder to catch her breath, and her skin was beginning to soften in places. While she had come a long way, she was still not completely used to this body, nor had she had the opportunity to build the stamina she needed for such a drawn-out battle.

Kirishima cursed to herself: this was not the time to run out of energy, not in the very centre of the battlefield, not when she had finally met up with Bakugou. She wouldn't let him see her fail like this; how could she expect him to rely on someone who couldn't keep up with him?

She could go further; she had to.

Bakugou could see that she had begun to slow down, her movements were becoming sloppier, and she was getting distracted. So much so that she missed the man that was approaching fast to her left and the fist that was now flying into the side of her head.

"Shit!" Bakugou blasted away the weak bastard that had been sneaking around his feet and landed between Kirishima and her attacker, intercepting a second blow, and he helped her to stay on her feet. It had been a hard blow, and he wouldn't have been surprised if her brain had been knocked around in her skull.

Kirishima shook her head as she felt something wet trickle down the side of her face, too sudden to be sweat.

"What the fuck are you doing? First rule: don't let your guard down." Bakugou glared at her as he knocked out another man who had tried to sneak up on him, taking the brown scarf that had been around his neck and flinging him off into the distance like a shooting star.

Kirishima winced slightly as the blonde quickly (and not softly, might she add) tied the material around her head before turning back to her and blasting another one.

"Eye on the prize, dumbass,"

The redhead, while shocked, found her feet again, pressed up against him, and set her sights on the next opponent. While she couldn't keep up her hardening for long periods of time just yet, she could do short times in smaller areas, and she used that to her advantage. A stronger punch and guard were all she needed for these guys, and with the blonde at her back, she didn't need to worry about anyone getting her from behind.

The sun would soon set, and with it would end the battle. Both sides were thinned out considerably, and thankfully, it seemed no one from their side had sustained any critical injuries. Well, other than Midoriya, who had a purple arm, but she had been informed that he did that to himself more often than not, she didn't get it, but she wasn't going to pry.

Both sides were bruised and scratched, but there were no fatalities. As this was meant to be a friendly display of strength between guilds, it was an unspoken rule that deadly force was frowned upon.

Kirishima slumped against the blonde and grinned over her shoulder at him as the last of the opposing guild fell by their hands. Roaring roars of victory shouted out around her, and friendly faces congratulated her on her first battle.

It was a moment she would remember forever: laughter and comradery shrouded in the glow of glory, a moment of light before the coming darkness.

"Ah derrrrrr~" Kirishima stared with her mouth hanging open as Kaminari floated past her with a distant look in his eyes and a slight drool forming. Had he been hit too hard?

"God damn it, Kaminari!" Jiro shuffled closely behind him, sounding annoyed, but the redhead could see the amusement on her face. "Do you have to fry your circuits every time?"

...fry?

"He does that; don't mind him," Sero sighed with a smile. "Way to go, Red Riot." With another grin, Sero wandered off to follow his friend.

They spent a short while fixing their wounds before preparing to set off for the long trek home before the coming darkness was interrupted by a sudden flare.

"What is that?" Ashido raised her hand to her eyes as she looked up at the sky. Heads turned in time to see hundreds of lights blaze in the sky, followed by screams.
