My Hero Academia: Blood and Fire

"You heroes are all diseased, greedy, vain, and emotional fools... you think you know what you're doing, but this world is far too corrupted by the Quirks that have infected everyone." Chisaki stated, showing them that he was focused on his own goals and less on what was going on with Celestia, even though to him this proved his point, the hero in front of him had been far too emotional over his treatment of Eri and she had exploded into her current appearance, "Give Eri to me... now. Her Quirk is a curse upon this world... no, her very existence is cursed... the first time she used her Quirk she erased her actual father from existence, and through what I've done to her I've been able to produce something that, when perfected, will utterly erase one's Quirk. I can destroy this disease ridden world, and Eri is the key to doing it."

"No, you won't lay a single hand on Eri's head, not after everything you've done to her." Celestia remarked, where she and the others found that Chisaki was definitely debating what to do since it looked like they would be fighting soon, which was why she turned her head a little as she focused on who was behind her, "Sister, am I correct in assuming that you have access to all of your power?"

It wasn't hard for Selene to understand the question, Celestia was asking if Selene's magical power, which she had none of when they first arrived in this world, had returned after the seal had been broken, and, sure enough, Selene could feel the magic coursing through her body now that her sister's memories had returned.

"Yes... surprisingly." Selene replied, though she was still gauging the situation that was unfolding, she wasn't entirely sure if this was the Princess of the Sun she was talking to, which would be a massive problem for her once Chisaki was done with, or if this was her sister, the version of Celestia that she actually loved, "You want a barrier around the others?"

"If you would." Celestia answered, where Selene nodded and focused her mind for a moment, where a transparent blue spherical barrier appeared around her, Eri, Izuku, and the rest of the hero group, something that surprised Aizawa and the others for a moment, though Selene smiled a little, because while she wasn't used to using magic in this form she could see that she retained her and Luna's knowledge on how to use magic.

In the following moment the ground around them buckled as spikes emerged out of everywhere, all of the walls and even the parts of the ceiling that hadn't been damaged by Celestia's transformation, and Selene found that her barrier worked out quite well, there was no damage to them as the rocks broke upon her magic.

"And even you, Celestia Midoriya, are arrogant like all of the other heroes, taking your eyes off of a villain for just a moment and dying in seconds... really wastes your Awakening." Chisaki remarked, where it looked like he was having a good time, as it looked like he was starting to laugh, like this just proved his point and there was nothing anyone could do to change his view on the world, before he noticed that the area Celestia was in was bare and she was untouched, "What the..."

"I wield the power of the sun, you moron... did you really think this would work?" Celestia asked, because the area that was around her had been melted by her power and since her power was still in use that meant it didn't matter what Chisaki did, her solar power simply dealt with anything that was around her, causing her to shift her stance, "Prepare yourself, Chisaki, because I'm bringing an end to your operations. Now!"

Chisaki found that Celestia rushed through the air and appeared nearby before he could even react to her movement, where he found her sword coming close to where he was standing, causing him to duck as quickly as he could before touching the floor and sending a surge of spikes at her. Sure enough he confirmed what had just happened, the flaming aura she had just melted the rock like it was nothing, yet at the same time the spikes he sent towards the bubble around Selene's group didn't shake at all, it remained intact as if nothing had struck it. While that happened he found that Ryukyu was flying overhead, as it looked like she and her interns had come to investigate, while at the same time his pawn that had been sent to keep them out of the base came to the area as well, meaning everyone in his gang was useless right now. Sure enough the gatekeeper jumped down into the area he was standing in, where Chisaki made up his mind as he activated his Quick on each of his pawns and his own body, because if Celestia was going to be his opponent he needed enough power to bring her down so he could claim Eri.

The ground shuddered as Chisaki merged his body with the bodies of his couple of followers, merging them into what could pass as a flesh dragon with a crow mouth, which seemed to be where he positioned his actual body, while at the same time breaking apart the area that was around them, causing Celestia to extend her hand as she forced him up into the air while making sure Ryukyu's group was out of harms way.

"Behold the power of Overhaul, he who will bring destruction and doom to the world of Quirks!" Chisaki shouted, which was like a roar coming from the beast he had transformed his body into, like he had combined everything good about each of his pawns into his body, to make sure his newfound power could stand up to her, "What can you do against my power!?"

"Wow, and here I thought the villains back home loved to talk and hype themselves up." Celestia remarked, where Selene and the others watched as scales started to form all over her body, she was shifting into her hybrid dragon form while still using Sunshine on top of it, allowing Selene to see that her sister's spine, spine of her tail, and the crest of her head were set on fire, just like when Celestia used The One, further confirmation that her power had fully returned, "Time to shut him up and lock him away."

Celestia rushed into the air without wasting time and flipped forward as Chisaki attacked her, where Selene found that she landed on his arm and ran up it, the edge of Solarion cutting through both the flesh dragon's middle claw, the middle of it's arm, and through the middle of it's shoulder, cutting a chunk cleanly off as she appeared behind her foe. Chisaki, despite that fact, focused and reattached the severed piece like it was nothing, even though Selene could see fiery lines that revealed where the insane Yakuza had been hit, meaning being slashed by the sun's power left lasting damage. Celestia, on the other hand, fell out of the air for a moment and stopped below the flesh dragon, where she fired a few sun orbs into it's chest to blast holes into Chisaki's extended body, damaging it more and more as time went on, while surprising the heroes that were watching this unfold. Celestia wasted no time in turning her blade and slashed through both the flesh dragon's arms and legs, where she found that Chisaki activated his Quirk once more and broke everything down, creating a swirling mass of bits in the air with his body in the direct center.

What she discovered, however, was that it was just putting his body back together, recreating the flesh dragon form while opening the crow beak so he could see her again, causing her to sigh as she rushed forward and continued to overpower the villain that she was keeping in the air.

"Okay, that's not what I was expecting." a voice said, where Selene found that the female robed figure appeared nearby and seemed to be staring up at the battle that was raging above them, something she wasn't surprised by since the figure had lost her glaive to Celestia's flaming aura, and yet the robed wolf person drew a pair of swords, "Oh well, I'll just take Eri now and get out of here... can't leave someone with her power in the hands of such morons."

"Funny, coming from someone whose not paying attention to potential enemies." Selene replied, where she made sure Eri was in the hands of Izuku before teleporting out of the barrier she had created, something that caused the figure to turn in surprise as she brought the battleaxe down on where the wolf was standing, causing her to stop Nightfell with her swords, but Selene could hear them crack under the pressure.

Aizawa found that something interesting happened as Selene clashed with the mysterious figure, her back shuddered before a pair of dark feathery wings, matching the ones Celestia had before moving into her current form and colored to match Selene's body, grew out of her back, and yet she also grew a horn in the middle of her forehead.

"Oh man, you too?!" the robed figure remarked, where she found that Selene's power seemed to increase as the cracks in her blades grew, something that caused her to jump backwards as the blades snapped in half, though the wolf growled for a moment as the weapons disappeared entirely, "One alicorn is bad enough, but two... I draw the line at that, especially since most of my power is sealed to make sure Dymalis, Sairozormi, and Her can't feel me."

"Who? No, you know what, I'm taking you out, now." Selene stated, causing her to rush forward as she swung the battleaxe down at the area that the figure was standing in, though instead of her weapon hitting the figure she found that the robed wolf vanished, as in she opened a portal and jumped through it before Selene could hit her, "Okay, we'll have to keep an eye out for her in the future... I suspect we'll see her again, at some point... and maybe the people she named as well."

As she said that the air shuddered as Celestia rushed through the air and continued to slice through the flesh dragon like it was nothing, not that Selene was surprised by this discovery since her sister wasn't holding back in the slightest, though at the same time she found that the sun wasn't being used by Celestia. She understood why her sister wasn't bothering to use her power to move the sun, there was no need for her to reveal that fact, nor did she need that power against Chisaki, not when her empowered hybrid form was able to do so now that she was using Sunshine and Dragon at the same time. With that in mind she returned to the barrier and slipped inside without delay, where she made sure Eri was fine, even though the girl was a little worried about what was going on with Celestia and that meant her Quirk was active a little, coursing through Izuku's body a bit, but that stopped when she returned. Together they watched as Celestia continued to push Chisaki around in the air, fiery slashes cutting through the flesh like it was nothing, and even when he transformed into something else, like gave himself giant flesh limbs, a giant flesh lizard form, or even the form of a giant flesh crow, nothing seemed to work for him.

Selene wasn't even remotely surprised by this, even though she could see that Aizawa and the others were stunned by this, causing her to smile as her sister continued to push Chisaki around like he was a simple toy and she was a cat that was just playing with him, before Chisaki jumped back and reformed once more.

"It's about time I ended this farce. Holy Sword..." Celestia said, as she was done fighting Chisaki, the constant slashing and blasting him had quelled some of the burning rage that was inside her, and since Eri was safe she didn't feel the need to do anything more than what was going on right now, before she raised her sword and let flames dance around the edge as she brought it down in a vertical line in front of her, "Celestia."

In the next moment Chisaki found a diagonal slash appearing on his chest, one that cut through his flesh and spilled a lot of his blood in the process, causing him to fall out of the air as Celestia caught him with some power and laid him on a pile of rocks a little harshly. With that Celestia nodded to Selene and her sister moved, both to carry Eri up to her, as she did away with the barrier, and to gather up some of Chisaki's blood so she could obtain the Overhaul Quirk, and it wasn't long before she understood why as Celestia let Eri work her magic. Eri was able to separate Chisaki from each of the Precepts he had merged into his body to make the flesh forms he had used to try and bring Celestia down, and it wasn't long before each of them were back on the ground, fully knocked out so they couldn't retaliate against her and the heroes. Once that was done Celestia picked Eri up and smiled as she turned away from the fallen villain, allowing the heroes to get up here so they could some and arrest Chisaki, though instead of staying down Chisaki got up and reached for Eri again, like claiming her would be the key to his victory if he broke her mind again.

Celestia, seeing that coming, simply turned her sword and severed both of Chisaki's hands, eliminating his ability to use his Quirk entirely, while the solar flames reduced his hands to ash as he crumbled to the ground in agony, even though his new burns had cauterized the wounds to prevent him from bleeding out.

"Goodbye, Chisaki. Enjoy your time behind bars." Celestia said, before delivering a punch that knocked the villain out, which put a smile on her face and the faces of her siblings, though in the next moment she reverted to her base form and quickly returned Solarion to where she stored it.

Selene nodded as she, Celestia, and Izuku tended to Eri, making sure she was perfectly fine after everything that happened to her recently, even though she did have to wonder about the robed figure and the people she had mentioned, but figured they would deal with them at some point in the near future and was looking forward to whatever happened next.
