My Hero Academia: Blood and Fire

Celestia found that Selene wasted no time in joining her and the others as Sir Nighteye pushed into the main building, all while leaving the rounding up of villains to those that were following him, which meant that Ryukyu didn't need Selene with her and was allowing her to chase after Chisaki. Of course some of the minor heroes and the police took down the goons that were guarding the main entrance and the main hall they were moving through, before Sir Nighteye stopped at a indent in the wall, a vase on a pedestal of sorts that had been built in the wall. He revealed that there was a hidden sequence one had to press in the tiles that were below the vase, which he had seen thanks to his own Quirk when he used it on that one member of the Precepts to confirm most of the information they had obtained recently. Sure enough his information gave him the ability to open the hidden door that was in the wall, like this was a ninja house, though as some villains came out of the passage they encountered some resistance from the heroes.

By that Celestia meant that Aizawa erased their Quirks for a moment, the centipede hero wrapped two of them up with his centipede arms, and Bubble Girl released some bubbles from her skin before forcing the third villain to get an eyeful of her bubbles, stunning him so he could be arrested.

Behind the hidden passage they found a set of stairs leading down into the basement, and when they discovered a dead end Mirio slipped his helmet off, as his suit was made with his own hairs so it would phase through things with him, which let him confirm that this was a false wall. Chisaki or one of his followers had set it up in the hopes of buying time for them to get out of the area, a decent plan, though as Mirio returned to them both Celestia and Selene stepped forward, their weapons smashing though the wall like it was made of tofu. In the next moment the basement started to change around them, it was contorting and twisting before their eyes, which meant it was Joi Irinaka, or Mimic as he was known as, as his Quirk Mimicry allowed him to merge his body and mind into an object to give him full control over it. Of course his power only allowed him to inhabit small items, like plush toys or a small refrigerator, but the fact that the entire basement was twisting like this told them that he must have taken a heavy dose of Trigger, the Awakening inducing drug.

Many of them were dropped into the level that was below them, not enough to do any harm to anyone, while Mirio kept on the path he was following since he was the only one not caught by this move, where they found three more members of the Precepts waiting for them.

"Hey there, girl, that's a nice sword you have there." one of the figures, wearing a suit and a plague beak, remarked, though at the same time Setsuno, as that was his name, held a hand out and the heroes found that Solarion flew into his hand, but Celestia and Selene weren't even surprised or worried as his fingers closed around the handle and he instantly dropped it with a panicked look in his eyes, and a heavy burn on his right hand, "Ouch... what in the world was that?"

"Solarion, a weapon that only I can wield since it's part of my Quirk... anyone else is burned when they try to hold it." Celestia replied, though at the same time she rushed at him as Aizawa used his Quirk on the trio, taking away their powers for a time, where she slammed her hand into the side of Setsuno's head and knocked him into the wall while calling her blade back to her side, with Aizawa knocking out the guy with the scarecrow mask.

Sure enough Tamaki told them that he could handle the trio, this was his duty, therefore allowing Celestia and Selene to join Sir Nighteye on the others as they rushed deeper into Chisaki's lair, though it wasn't long before they found Mimic altering the rest of the basement randomly to keep them at bay. It was clear that he had taken a rather potent dose of Trigger, since it was lasting longer than the Japanese variant was supposed to last for, and he was able to divert some of them into other areas, such as Fat Gum and Eijiro both moving to stop someone else from being knocked away and were cut off from the rest of the group. In addition to that Mimic focused on trying to separate Celestia and Selene from Sir Nighteye and Aizawa, but found that such a thing was utterly impossible as both of them slashed through everything that was sent at them, as he tried to send spikes and whatnot to harm them, but their adamantine weapons tore through the material with ease. Such a thing told Aizawa that even Chisaki, one of the smartest villains they had seen so far, had underestimated the sisters, which was common when he thought about it since no one seemed to know what to do with the sisters.

As they moved, however, Sir Nighteye found out something that was odd, there were no members of the League of Villains in the basement, rather it looked like whatever talk Chisaki must have had with Tomura must have failed, and it sure looked like Tomura was watching, waiting for the Precepts to be destroyed.

"I'd erase Mimic's Quirk, but he's hiding inside the twisting halls he's created." Aizawa commented, as he knew Sir Nighteye was getting annoyed by this, even though the other hero, Rock Lock, seemed to think that this was entirely the fault of Sir Nighteye, even though there was no way to account for anything that had happened so far.

"Allow me." Izuku said, where he focused for a moment and slipped into his Full Cowl, so the moment his sisters attacked the walls again he rushed into the center of the ceiling, something that allowed Aizawa to see that he smashed through it with ease and revealed Mimic's human form, allowing him to erase his Quirk as Izuku knocked him out, reverting the area back to what it used to be.

"Chisaki's above us, since we fell one floor down... time to stop wasting time." Celestia remarked, only to shift her stance for a moment as she loosed a small orb of solar power into the ceiling, just enough to blast open a path back to the upper floor without damaging anything else, thus allowing her and Selene to leap up into the upper floor, only to find that Mirio was in the area as well.

Instead of wasting time talking, like one would normally do, the sisters nodded to Mirio as Izuku aided the others in leaping up to the new path, allowing them to continue down the hallway that was in front of them, and it wasn't long before each of them found Chisaki and another figure, one of the Precepts, casually walking away from them... before Celestia paused as she saw Eri in the other figure's arms, who was struggling to escape.

"Celestia! Selene! Save me!" Eri cried out, because the moment she noticed the pair she knew she had to call out to them, as the hope the pair had given her hadn't burned out and she knew that if she could be saved from this situation it would be in their hands, even though she had no idea where the black robed figure who had grabbed her was located.

"I... I don't understand... we left her in UA. Why is Eri here?" Izuku asked, as he and the others, part of the back of the group, were surprised by this information, even though it was easy to see that Celestia, Selene, and Mirio were just standing there, staring at Chisaki as he turned and looked at the group with the same look of disgust he had for heroes, before his phone, plus Aizawa's and Sir Nighteye's, went off, causing him to check for a brief second, "It's from the Principle... he's informing us that someone warped into UA and made off with Eri, before they could even react to what was going on."

"Guilty as charged." a voice said, where they found a black robed figure, a wolf mutant based on the bits of her they could see, appearing out of thin air next to Chisaki, while at the same time a figure rested on the ceiling, walking like a spider, with another masked figure off to their foe's right that seemed to have a gun, "I guess you failed, heroes, because Eri is back where she belongs... and it's only a matter of time until the Precepts' plan is completed."

Selene opened her mouth to say something, but instantly stopped as soon as she felt it, the seal on Celestia cracked as her sister took in the scene that was in front of her, in fact it was cracking far worse than what she had seen previously, and yet it looked like the two members of the Precepts focused on attacking her. One seemed to be focused on trying to make her feel drunk while the other seemed to be firing a whole clip in her direction, as he knew that she was dangerous, and yet nothing seemed to work as the clip of bullets stopped in the air in front of Celestia. In that moment Selene knew what this was, the sheer rage that was burning inside her sister had well and truly fractured the seal, her magic was leaking out and she had to assume that included the knowledge on how to use her magic, thus allowing her to stop the bullets with ease. Sure enough the bullets glowed for a moment as Celestia's solar power washed over them, reducing them to ash in an instant, and in the next moment her sister flashed through the air, moving faster than she had in the past, smashing the ceiling villain into the ceiling, the gun one into the wall, and knocked the one holding Eri back.

In the following second the black robed wolf summoned a glaive and swung it at Celestia, only to find that Celestia's flaming aura melted the weapon like it was nothing, and yet Selene's sister jumped back with Eri in her hands, who held onto her for a moment as Chisaki growled at them.

"Give Eri back!" Chisaki declared, rushing at Celestia while her back was turned towards him, though at the same time Selene found that he stopped in his tracks, by telekinesis to be exact, and the look at was in Celestia's eyes was exactly what she had seen in the past, the dragon slits that reminded her of Daybreaker too much, and she turned and looked at Chisaki with a look of pure hatred in her eyes.

In the following moment Eri, who was already emotional from being taken against her will and having cried out for Celestia to save her, seemed to send a last burst of her power through Celestia's body, like before, where Selene could practically feel the seal crack even more like it was nothing. In fact the seal wasn't just cracking at a dangerous rate, she was sure that the entire thing was breaking, maybe even dissolving entirely as her sister's rage took over, and Selene thought that as a surge of power rushed out from where Celestia was standing, a physical representation of the seal appearing in the form of her Cutie Mark. It appeared around the ground she was standing on, where Selene watched as the magical seal dissolved before her eyes, as in the magic that had been placed on her was sundered by the combination of Eri's Quirk and the rage that was coursing through Celestia's body. Chisaki flew backwards into the defeated members of the Precepts, surprising Aizawa and the others for a moment, as the air around Celestia sparked a little, causing Celestia to hand Eri over to Selene for a moment before a pillar of fiery energy erupted from where she was standing.

"I was right, we shouldn't have brought her... she's experiencing an Awakening." Aizawa said, as this was the worst possible thing for them right now, because an emotional and volatile Celestia was the last thing they needed right now, especially since rage made everyone lose sight of what was important, and it seemed like she was no different.

"Actually, that's not entirely accurate... She is waking up." Selene remarked, as she knew to the people of this world that this would be seen as an awakening, the moment where one experienced an emotional episode that forced their Quirk to evolve, her father had talked about it a few times in the past, but that wasn't even close to what they were seeing, Celestia was just returning to her full power, hence 'waking up'.

Aizawa opened his mouth to say something, but before he could actually say anything the pillar of solar energy, for that was what it was, started to dissipate, revealing a hole above them that went to the street, they were right under the road outside the house the Precepts had been using as a base, just down the road by his estimates. For a moment he thought he saw an entirely different form inside the solar flames, a horse or even a pony when he took Selene's body into consideration, before Celestia, in all her bipedal glory, emerged from the flames her Awakening had created. In the following moment he noticed something odd, Celestia was no longer human, rather she looked like Selene, a mutant in the form of a pony, anthro based on what some called this form, and her hair was longer than before and now had multiple colors running through it, and she had a tail that matched. In addition to that Aizawa noticed that Celestia now had a horn in the middle of her forehead, like a unicorn, and she had a pair of elegant feathered wings growing out of her back, so unlike her dragon ones, plus she had a stern look on her face that seemed to make even him, Sir Nighteye, and Izuku step back a little.

The other thing he noticed was that the solar aura around Celestia was making the hallway twist on it's own, in fact he was sure that the floor might be in the process of melting, reminding him of the terrifying power the girl possessed and that fact made him terrified of what they might seen next.

"Nightmare Moon... Selene, I mean... hold Eri tight and don't let her go." Celestia said, where Selene found that her thoughts were confirmed, the seal was broken, her sister's memories and power had been restored to her, in fact she might even possess the power to switch between her human form, anthro form, and alicorn pony form, if what she had seen was right, before Celestia faced Chisaki, "I'm going to end this."

Selene nodded as she held Eri, who had calmed down after escaping Chisaki's grasp, though this really made her wonder what was going to happen next since there was no telling what their enemy might do now that he was facing the full power of the sun, but she was looking forward to seeing Chisaki finally meet his end, all while worrying about what would come after this important event.
