Chapter Fifthteen

Fatal Battle

The demon had made his declaration of war upon Hero Society by killing Thirteen. Lily simply stared at the remains of her body as the world around her went silent. It wasn't because she saw the dead body of a pro hero. Given her history of killing villains she was used to seeing dead bodies, but it was the fact that the demon pillar's attack happened so face was what caught her off guard. Had it been her instead of Thirteen, she would be dead...right.

"Lily, stay calm and focus." Artoria said as it caused Lily to blink. "This is your first time facing something like this. And I understand you're scared, but right now you need to get your thoughts together and fight so you can save the others. Now get your act together. This is no different than how you were when you lived on the streets." Lily took a deep breath before slapping her own face with her own hands to regain her composure. She then looked over at Kaminari and walked over to him. She soon places her hands on his face as a means to calm him down before talking.

"Kaminari, are you able to get in contact with the school with your phone or something?"

"I think so...I'll have to check." He said before pulling out his cellphone to check. "Crap, no signal."

"Anyone else with their cell phones or something can get a connection with the school?" Lily asked as some of the students checked their phones to see if they could. But just like with Kaminari's phone, they too didn't have a signal on their phones. "Damn, guess we'll have to go with plan B then."

"Do you have a way to get us out of here?" Aoyama asked as Lily walked in front of the group.

"That thing's the reason why we're locked here. So killing him will get us out of here."

"You're not thinking of fighting that thing are you!?" Mineta said as the bunny girl nodded. "Did you not see what it did to Thirteen!?"

"Yeah, I did."

"You can't seriously think you can win, right?" Iida said, flabbergasted at how casual Lily was taking all this. "If anything, we need to think of a way to escape."

"You guys can do that. While I go and save the bagworm of a teacher." She said before noticing Halphas shot off Aizawa's leg the moment he landed after dodging another beam attack as the stumbles to the ground. "Which will be sooner than expected." The bunny girl said as the magic circuits in her body lit up and caused her to fly off towards Aizawa at breakneck speed. Just as the beam of magic was about to strike him down, the pseudo servant landed in front of Aizawa and deflected the beam off to the side with her sword. Upon being deflected, it would hit the shipwreck area as it caused the boat it hit to explode.

"What do you think you're doing!?" Aizawa yelled in both pain and anger at Lily. "Do you know how much trouble you're in for-"

"Saving your ass from being turned into swisscheese? You're welcome by the way." She said before focusing her attention onto the demon god pillar.

"You must be the Grand Servant summoned to save the world?" Halphas said as he eyed the pseudo servant up and down. "I must say, I'm not very impressed if I'm being honest."

"Great, so he knows what I am." Lily thought as she slightly looked over at Aizawa as he had a confused expression on his face while treating his wound."Knowing the confused expression on his face, he'll most likely ask questions about what he meant...or worse."

"I'm sure you already know who I am, given the conversation that you heard from me talking to that human. Which I have to say, he lasted longer than the one that tried to make a getaway with the children." He said with a slight chuckle. "It's been far too long since I've killed someone like that. Being sent back in time to gather nothing but magic and watch the humans kill themselves was boring."

"Riveting how about you leave us the fuck alone, or else I'll have to kill you where you stand."

"Such fire in your words little girl. I like it~" Halphas said before focusing his eyes on her, Aizawa and the students. "My original plan was to kill everyone here. But I'm willing to give you a chance to live another day." He said, which caused everyone to blink in surprise.

"You can't be serious? You expect me to believe that you'll let us live?" Lily asked as she raised an eyebrow at the demon. "There has to be a catch to this, isn't there?"

"Indeed. There is a catch to me letting you all go." Halphas's eyes glowed for a quick second. A few feet off to the side of her and Aizawa, a portal appeared from the ground as something was making its way out of it. "My King has allowed me to have a little bit of fun with a test subject that we recently acquired last night. I want to see how well he does against someone like you." He said as the being made its way out of the portal. Lily's eyes widened upon seeing the man's disfigured body. It looked similar to that of Endeavor's physic, only he had no hair on his head, no eyes, and arms the size of a giant oak tree trunk.

"...The fuck is did you do to him!? He looks like Arnold Schwarzenegger on steroids for a monster movie!" Lily said as she watched the man walk in front of Halphas in a sluggish and painful manner.

"The king has made a few alterations to him to make him be similar to that of a heroic spirit. A berserker class, given how he has multiple powers, or...quirks as you humans call them." Halphas said as the man growled like a primal beast. "Your requirement to survive is that you must kill this man before he kills you. Do that and I'll let you all go. If not...then well...I'm sure you know what to expect."

"You monsters. You expect us to go along with that plan of-"

"I accept." Lily said, interrupting Aizawa's statement as he looked over at her with a shocked expression on his face.

"Wonderful! As a means of good will, I will allow you to prepare yourself before the fight. But don't take too long...I might change my mind and just kill you all myself~"

"Well aren't you a generous demon god pillar." She said before looking over at Aizawa who was looking at her in disappointment and anger. "What?"

"...If we survive this. You will be going to prison."

"You have got to be kidding me? I don't think now is the time for you to be a stickler for the rules."

"It's a pro-heroes job to deal with villains. Non-licenced heroes or citizens aren't allowed to fight villains. What you're doing is endangering yourself and others around you."

"Yeah cause you and Thirteen are doing a really good job at this point in doing your job." Lily said before focusing her attention onto Halphas and AFO. "Look around you dude. Thirteen is dead, the students are scared shitless, and you're down a leg. Now unless you can regrow your leg, I suggest you leave this area so you don't get yourself killed."

"You expect me to leave our fate in the hands of a villain like-" Before Aizawa could finish, he felt a surge of pain in his abdomen as he saw Lily appear in front of him with a strong punch to his gut. He soon felt himself being sent flying backwards towards the student as Seto took notice and caught him.

"It's sad to see how humans are nowadays." Halphas said as Lily turned her attention onto the demon god pillar. "You think he would allow you to fight without complications, but it's sad to see how the world is now."

"So you've been around a long time huh?"

"Two-thousand years to be accurate. We've been gathering magical energy during that time for our King. But sadly it's not enough. This world is limited when it comes to magic and it's making things difficult for use to fulfill our mission to incinerate the human race."

"Much as I have my own personal issues with how this world is run. I'm kind of against having it being burned to the ground. Especially by a beast that only focuses on the bad parts of humanity."

"And you think they're good parts of humanity? Humans are nothing more than greedy, selfish, uncaring flesh of meat that are nothing good but food for us demons " He said before eyeing some of the girls. "The females might be useful for breeding demonic beasts...after some modification-" Halphas felt a surge of pain on one of his eyes, as blood spewed out the eye Lily cut as he let out a scream of pain.

"Remember the agreement asshole." Lily said as she gave Halphas a death stare. "The next attack will be much deeper and painful."

"All For One! Kill this human in the name of The Demon King Goetia!" Halphas said as AFO let out a primal roar as he lunged himself at Lily like a bullet. The circuit lines in her arms glowed as she brought her sword up. The moment AFO was inches toward her face, she quickly smacked him in the face with the blade part of her sword and sent him flying off toward the side of the steps. The man slowly pulled himself up from the man sized crater as Lily noticed the wound on his face quickly healed

"Oh great, he can regenerate his wounds. How nice." Lily thought as she quickly jumped into the air to avoid the charging monster's right hook. She soon lands onto AFO's arm and impales her sword into the joint that connects his arm and cuts his arm off like a knife through butter. She quickly jumps off of his shoulder to avoid being grabbed by him. As she lands, she turns around to see his arm quickly regenerating to the size of her arm for a moment before he activates multiple quirks to increase in size and strength. "Oh fuck you whoever made this walking abomination!"

"Pretty sure it was Goetia that made him like this." Artoria asked as Lily quickly brought her sword up to quickly parry away AFO bone like weapon attack after appearing in front of her again and form a spear out of bone into his hands.

"Any way to get around his regenerative ability?" She asked while parrying most of AFO's attacks as she felt some of them pierce through the chainmail covering her arms and graze her skin.

"Sadly you don't have anything with a curse towards healing abilities. But seeing how it's still human, cutting off his head should prevent it from regenerating. If that doesn't work, then you'll have to use excalibur just like you did with Bakugo. Only you need to hit him dead on."

"Hitting him with a powerful beam takes time to gather up the necessary magic from the planet. Which isn't a lot, seeing how there's not much magic in this world." Lily said before pulling away from AFO just as he swung his spear at her head. Upon landing away from him, her eyes widened as she was sent flying by a fist making contact with her face. "Not to mention he's fast!"

"Then you'll have to use the magic inside you. Fair warning, you can only do this five times." Artoria said as Lily crashed into the wall that leads to the fire hazard building. AFO quickly launched himself at her like a cannonball as she used her mana to increase her body's defence and pushed through the wall of the building and landed back first onto the ground. She soon lets out a gasp of air from feeling the wind knocked out of her due to the force behind the fall and begins to cough violently.

Before she had time to recover, the bunny girl felt her leg being grabbed as AFO swung her wound like a towel before slamming her hard onto the ground multiple times like a ragdoll. He continues this for a good five seconds before throwing her off to the side. The bunny girl made contact with a stop sign head first before bouncing off it and landed onto the top of a nearby building.

"Were it not for Avalon's healing ability, I would be dead by now...though I wish it could cut off the pain I was feeling." Lily thought as she felt the fractures in her skull and broken bones in her body repair themselves. "Fuck he hits hard."

Just as Lily pulled herself up, AFO jumped above her and was about to deliver a devastating and destructive punch. The magic circuit in her legs lit up as she quickly lunged herself off the building she was on as the punch missed her, but it did make contact with the building as it destroyed it completely. Lily brought her sword up for a moment as the circuits in her arms lit up. She then descends down towards the hulking berserker-like-human in a spinning motion as she cuts off part of his right arm. The moment she lands, she quickly launches herself up towards him again as she cuts off his whole left arm. Once she was above him, her sword became visible and glowed bright yellow.

"Eat this! Excalibur!" She yelled before swinging her sword at the air which in turn fired off a beam of holy light and magic at AFO as he was sent falling towards the ground. The moment the beam made contact to the ground, a huge explosion erupted from it as it sent Lily flying out of the fire hazard building due to the force behind the explosion and due to her being in the air. "Haha! Bet you can't recover from that!?" She yelled before hearing something move within the huge dust cloud she made. She squinted her eyes for a moment as they widened upon seeing AFO flying towards her with a fist brought back in an attempt to punch her. "What the hell!? He can fly!?"

The pseudo servant activated her quirk as she pushed herself down to dodge the oncoming punch. As he descends towards the shipwreck area, Lily took this as an opportunity to fire off excalibur again. The beam of holy light made contact with AFO as he was sent deep into the water of the shipwreck area.

"That should keep him down for a while." Lily said as she looked over at her classmates trying to break the tentacles off the entrance. But to no avail. "Seriously? Why the fuck hasn't Midoriya use his super strength to blow the door open?"

"It could be that he's afraid of having his entire arm broken. Remember from the training session you had while watching his match?"

"Now's not the time to worry about broken bones. Now is the time to escape with your life." Lily said as she was about to fly over to where they were, only to hear the sound of something heavy flying out of the water and heading towards her. The look over to her right to see AFO heading towards as she quickly moves out of the way of him trying to grab her by the head. She soon counters by cutting off his newly formed arm that tried to grab her. The pseudo servant tried to lob the man's head off, only for him to pull his head back and counter with a headbutt to her head. Stunned from the headbutt, Lily was unable to avoid being grabbed by AFO as he started to squeeze her head.

Lily gritted her teeth from the pain she felt from feeling her skull cracking from the strength behind AFO as Lily brought her sword up into AFO's chest. Once embedded into him, she unleashes a glow of magic from her body and into her sword. Excalibur once again glowed as a beam of holy light shot out from where her sword was implanted. A hole could be seen once the beam died down as AFO released his hold on her head. Lily quickly moves above AFO's stunned body and cuts off his head.

"Haha! Now stay down you piece of-" Before Lily could finish her taunt, she felt the body of AFO's arms wrap around her and draw her into a bear hug of some kind. "Hey, what the hell!?" She yelled before noticing his body glowing and growing bigger and bigger by the second.

"This is not good. He's going to explode." Artoria said as Lily tried her best to struggle out of his grip. But all that did was increase his grip.

"Oh you have got to be kidding me!? Lily thought before looking over at Halphas who was watching them fight.

"You should've known that something like this could happen. After all, he is an experiment that Goetia wanted to test on. So far, it seems that this human couldn't handle the magic my king implanted into him. Perhaps it was too much for him to handle. But it doesn't matter, you failed to kill him so now you'll die once he explodes. And while you're dead, I'll be having fun killing the humans that are trying to escape."

"...Oh I am going to unleash hell upon you if I survive this!" Lily said as she felt herself being encased in AFO's muscle mass. "Please tell me that Avalon will protect me from something like this? Because right now I can't move and I doubt increasing my defence with magic isn't going to help."

"Avalon can't protect you from physical damage. If anything, it can heal you from critical injuries that would result in death...Though I will need to do something to you while you're out of commission for the next few seconds."

"...Immortality via regeneration from a sheath really sucks if you can feel pain."

"Such is the life you chose." Artoria said as Lily would feel AFO reach his breaking point. The bunny girl heard the sounds of muscles ripping and magic escaping from his body. All she could do was grit her teeth from the pain she felt from being squeezed to death, but soon the pain she felt vanished along with her vision as everything faded into darkness as AFO exploded.
