Chapter 25

Izuku had decided against telling Fuze and Youma about what actually happened at Nazarick and for good reason. Thankfully the odds of them finding Arche was extremely slim since she was in Shalltear's home. "Am I a bad person?" He asked. "Well, am I a villain specifically?" he'd told his friends of course, and Milim who'd decided to eavesdrop.

"Well, that was definitely fucked up." Kirishima said. "Like, beyond fucked up."

"Hold on, they're being brought back to life, sure as servants, but they'll be alive with new memories." Mina stated. "I mean, yeah he killed them, but at least he feels bad about it enough to the point where he's willing to give them a second chance." She sighed.

"Ribbit, it's a bit more complicated than it sounds since he was being watched by the other floor guardians; losing their high opinion and respect isn't exactly something he can afford to lose in the long run." Tsuyu stated.

"Nazarick is our ally, and in case of war; we need their strength in case things get really bad." Shoto said. "Villainous though his actions may have been to us—"

"I don't see the problem." Milim said. "They invaded and paid the price, all Izuku did was help his friend." She smiled. "Like a Demon Lord would." This wasn't what Izuku wanted to hear. "You would make a great Demon Lord!" before Izuku could say anything else, Shion burst into the room.

"Lord Izuku, we have a problem!" she exclaimed.

Jura Forest Federation – Midoriya – Administrative Building

Treyni's younger sister had show up in bad shape, she was nearly translucent, and had bad news; extremely bad news. "The beast Charybdis has revived once more." She said. "Its first destination is here, Midoriya." She stated.

"I know that I'm going to regret this, but what is Charybdis and how dangerous is it?" Izuku asked. "Also, how far away is it?"

"It's a beast that was sealed in the past, and my elder sister is restraining it as we speak but she won't be able to hold it for long." She stated.

'Great Sage.'

'Charybdis is a mindless, bloodthirsty, calamity-class monster that is capable of revival with time so the Hero sealed it.' Great Sage explained. 'It lacks a physical body because it is a spiritual lifeform, thus it requires a host for survival.' Not good, not at all.

"In that case, prepare for evacuations!" He ordered. "Benimaru, you know what to do!"

"Right!" he ran out to organize a counter attack.

"Everyone else, get ready for the fight of your lives!" be turned to Vest. "I need you to contact King Gazelle so we can receive assistance."

"Leave it to me." He said before leaving.

"Now, I need to—"

"Why don't you run?" Fuze asked. "It's no less than a calamity-class monster and the only reason it hasn't been made a demon lord is because of its lake of logical thought." He stated. "Are you planning to take on a Demon Lord in the future?" Izuku smirked.

"Maybe, but for now I just want to save my home and people; that's why I'm fighting." He said. "I ordered an evacuation in case I lose, as their leader I put them first of course." He looked to the man and smiled. "That's what a king does, right?"

"Oh god, you are just…"

"Hey, I have a request to ask of you."

Jura Forest Federation – Midoriya – Road to Midoriya

Izuku had contacted Ainz and explained the situation. This was the reason Cocytus was here to fight alongside Izuku's forces. Evileye would be assisting Shuna, and despite his insistence on staying back, his friends were staying to fight. "I should mention that Charybdis is Veldora's child."

"Wait what?"

"It was spawned from Veldora's magical aura and wields a fraction of his strength."

"Veldora?" Cocytus asked.

"The Storm Dragon that was sealed until a while back, he dissapeared, but he's incredibly strong." She said. "This means that magic is mostly ineffective against it because of its extra skill Magic Jamming that disturbs the flow of magic."

"So physical attacks are our only way of really hurting it." He concluded. "That just so happens to be my strong suit as a warrior." He said before taking out a blade that Izuku recognized. An odachi with the length exceeding 180cm. "God Slaying Emperor Blade is a divine weapon once wielded by my creator, the Supreme Being Warrior Takemikazuchi, it should be most effective against this beast."

"Charybdis is able to regenerate almost instantly, it's most likely the skill High Speed Regeneration, and what's more…"

"What more could there be?!" Izuku exclaimed.

"Because it originated from the spiritual world, it is accompanied by many megalodons." She said. The sound of facing a supposed to be extinct animal didn't sound very pleasing. "They too are immune to magic attacks as well."

"Well, we have the sword of Nazarick on our side, our chances of victory have definitely increased."

"Thank you, Lord Izuku, I am not worthy of such praise."

"You are, Ainz sent you here to assist with this problem, there's a reason for that." He said. 'Gluttony, I really need you to work, and now is a good time to use Hero of Monsters.' He silently said. 'Maybe benching Milim wasn't a good idea.'

"Milim, you're our last resort so I need you to conserve your strength."

'I have to admit that I did that because of some pride as well.' He sighed. He looked up and in the distance there it was, a giant one eyed, flying monster. It was accompanied by a couple dozen megalodons. "Get ready, for the fight of your lives!" they were ready, all of them. "Activate Skill: Hero of Monsters!" a green aura coated them all, increasing their strength times fifty. Hopefully it would be enough.

The first shot was fired via Benimaru's fully powered Hell Flare that managed to take down one of the megalodons. Its body completely burned. "A single lackey, that Magic Nullity is going to make things at lot more difficult."

Izuku flew into the air just as Charybdis let out a roar that ordered the megalodons to charge forward. The fight had officially started. "I can't let you pass!" Cocytus exclaimed, grabbing a megalodon just as it charged. It was pushing him back. "A lot of brute strength, however…" he lifted it up and slit its belly open. "Your underbelly is soft." He didn't have time to rest as more and more charged forward.

Mina found herself to be useful as she was able to be thrown up, and splashed her in the eyes and mouths of the megalodons. It was stronger than it usually was, way stronger. "Hero of Monsters, it effected me too, I felt it." She landed on its backs and let loose a torrent of acid that caused it to wildly spin out of control before crashing into one of it's own. Mina jumped off and landed in a tree. "I guess I'm considered a monster now, huh?" she got down and ran to one of the orcs. Without saying a word she kept forward and was thrown into the air, grabbing onto another megalodon. "I don't have a problem with that, Acid Hand!" Her hands tore into its eye sockets and began melting the inside.

"Is that all you got?!" Kirishima exclaimed before punching a megalodon downward just into for Hakurou to slice it into pieces. He looked to the ring that had been given to him, it was increasing his Hardening's overall abilities by 20 times. He couldn't crack the megalodons skin with a single punch, but he could redirect them. "I'm not useless damnit!" he was quickly pulled back. "What gives?!"

"Rushing in without a plan is something the two of you have in common." He pointed to Gobuta. "Calm down for a second and think about things before you get your head bitten off." In swift movements, he cut a megalodon into pieces. "Megalodon meat is extremely rare, now look for weakness in their armor and crush it!" he said letting go of the teen. Izuku watched the fighting for a few more minutes before Charybdis chose to act via laughing a barrage of scales at them. Izuku wasted no time in intercepting them.

"Gluttony!" a massive swirling mist of green and black magic came swirling out of his left hand, and swallowed the scales with ease. In the blink of an eye they were gone, and a couple dozen megalodons were coming his way. "Looks like it's my turn." He drew his sword. "One for All 75%, Muscle Augmentation!" He few forward faster that they could see. His blade cutting through the megalodons like a super heated knife cutting through butter. The teen flew upward a bit before crashing down on Charybdis's exposed flesh, stabbing into the flesh. "Corrosion!" he had jabbed his free hand into the open wound. "I know that I won't be able to absorb your main body, but I can still hurt you!" the massive beast roared.

The teen began running, his blade cutting the beast in a massive line. "There's some serious resistance, but you've never felt pain like this, have you?!" it roared in pain as it's wound began to heal and the scales came back. "Damnit!" he flew off of it.

"That was awesome!" Milim exclaimed.

"That must've taken some serious strength." Kirishima said. "I think it's upset—" Charybdis let out a loud roar of unbridled rage.

"Upset, it putting it nicely." Cocytus said.

"Scales!" a barrage rained down, and Izuku wouldn't make it in time to consume all of them. "Take cover!" everyone did this while Charybdis's attention was solely on Izuku.

"Get behind me, young ones." Cocytus said as the scales got closer. With speed that they didn't see coming, the floor guardian was able to redirect the scales that would've killed Mina and Kirishima. "These scales are harder than I thought, I'm actually having some difficulty!" moments later the unthinkable happened. God Slaying Emperor Blade shattered. "Impossible!" he turned around and shielded the two teen, taking multiple hits as a result until the barrage ceased.

"Cocytus!" Mina exclaimed. "Two of your arms—"

"Don't worry, now we can focus on attacking—" he fell to his knees. He was in very bad shape. "To think a weapon forged by my creator would be broken in such a way." He was still holding it. "Once more I have underestimated my opponent, and look what has happened…" he struggled to stand. The item that temporarily negated ranged attacks was broken as well.

"Cocytus." Geld said gaining his attention. "Retreat to Lady Shuna for medical care, your injuries warrant a full restore, you'll be back to fighting shape soon."

"Both my weapons—"

"You think we don't have spares, now go!" He exclaimed.

"I'll be back soon." The insect stated before limping away. 'How will I be able to go back to Nazarick and tell Lord Ainz that the blade was broken in such a way?' he had been defending those two humans. His first lose against the Lizardmen was humiliating, but this was probably much worse. 'Lord Ainz will most likely end my life for this.' He reached Shuna and the injured.

"What happened?!" Shuna exclaimed as he fell to his knees. "Get me a full restore, now!' she exclaimed. "Your weapon."

"Broken while I was defending those two human…Kirishima and Mina from a barrage of scales." He stated. "As a result, my creator's weapon paid the price."

"Lord Izuku can fix the blade." Cocytus looked to her in disbelief. "But, you saved two lives and in doing so you've saved more lives, since they'll save lives in this battle as well."

"I never thought of it that way." He stated.

"Which is more valuable, the lives of your comrades or a blade that can be fixed?" she asked.

"My comrades." There was no doubt about it, this was a battle that he would remember for the rest of his life. Shuna used the full restore on him and seconds later all of his wounds were healed, and he was given two large halberds. "You are a wise woman, I'm sure Lord Izuku will be grateful to have you as his wife."

"Oh, you really think so?" she was blushing.

"I know so." Soon the reinforcements from the Dwargon Nation would come, and the battle's tides would turn.

10 Hours Later

'Damn, we've been backed into a corner, we're running out of medicine, and we're burning out!' Charybdis wasn't close to death. 'I don't think that having Ainz here would've helped much either since he specializes in magic, but Momon might…' he sighed. 'No, he wouldn't help even as Momon.'

"Hate…you…Milim…" Izuku's eyes widened.

"I thought Charybdis was supposed to be a mindless monster, but I'm pretty sure it just said…"

"Mil—Milim!" Izuku stared at Charybdis.

"Great Sage, please explain."

'Notice: Signs of life have been detected.'

"Charybdis is alive so of course—"

'No, Charybdis has no physical form of its own.'

"The host." He said. "Milim, what can you tell me about Charybdis's host?" He asked.

"Let's see…" she used her Dragons Eye. "Hey, it's that guy, Forbio from before."

"Yeah, you…took him down with one hit." He let out a loud groan. "That thing is coming after you, not us."

"Don't worry, this is my fault, right?"

"Hm, well—"

"I'll fix this."

"Wow, you can sound so mature sometimes, it's surprising."

"Hey!"

"Can you hold back enough so that you don't kill him?"

"No problem."

"Thanks, Thought Communication." He said connecting to everyone. 'Attention, there's been change in plans; everyone fall back so you don't get killed in the attack!' Needless to say they obeyed without hesitation. 'Our last resort is being deployed!' Milim flew forward when everyone was at a safe distance.

"You caused my bestie and his subordinates some serious trouble, luckily for you, I'm going to hold back." She said. "Drago Buster!" a barrage of energy based blasts shot forward and annihilated Charybdis. Izuku caught Forbio moments later and landed onto the ground.

"Alright, Great Sage tell me what's going on inside."

'Affirmative: individual Forbio and Charybdis are 90% merged; in less that 1 hour he will revive as Charybdis once more.'

"Looks like I'll have to do something extreme." Izuku said.

"Like what?" Milim asked.

"Separate them completely and make sure that Charybdis can't ever revive again." She stated much to Milim's confusion. "Like emergency surgery." He took a deep 'breath' and then exhaled. "Shape Shifter, Gluttony." Both skills were activated at the same time with Great Sage managing both. Gluttony would consume everything that escaped as he removed Charybdis from Forbio's body. "I should gain some of its skills and increase my magicules a good bit, but not enough to make me as strong as Charybdis."

"Like with the Orc Lord?"

"Yeah, but this is a lot more complicated." Izuku stated as he continued to remove Charybdis from the demons body. "But, at least Charybdis won't be able to revive again." The process was taking a lot out of him though. A couple more minutes passed before it was done, and he was forced back into his slime form. "Damn, that was insane." He sighed. The fighting was over for now, but this fight had revealed how many dangerous monsters were out there. Aside from Milim and Veldora of course. 'I need to become stronger?' he looked to Milim. "Hey, Milim."

"Yeah?"

"How would one go about becoming a Demon Lord?"
