As I landed, Overhaul touched his shattered left leg, restoring it almost instantly. And his stamina and ki bars both barely dipped, compared to the amount of health he recovered. Which only reinforced my plan.

Right up to the moment I threw him, he kept making my decision clearer. He would attack my friends, so I needed to get him away from them. He could use the ground as a weapon, so the compartively thin deck of the garage would limit him. Or if he was stupid enough to use it, he would send us down to the lower level. A fall I was better equipped to survive. Also, I was hoping, based on what Eri had said and what Nezu-sensei leaked from police profiles, that he would be less likely to touch the grease, dirt, and gas stained floor of the carpark.

I had already picked the garage since there was less likely to be bystanders, and Overhaul's minions and Hadou-senpai couldn't see what I was going to do. The rest just locked it in.

He stood up. He glared at me murderously. I kicked a chunk of the broken wall up to my hand.

"Hogwarts Smash!" I threw it at him sidearm. He caught concrete with a smirk. But he couldn't fully supress a grimace as it broke something. He 'crushed' it, and then stealthily touched his injured palm.

Good. He wasn't teribly tough. While that should have hurt him more, at least it did hurt him. And he needed to channel his powers through his fingers. Or at least thought he needed to.

I charged forward, fist first, again. This time he didn't look as dismissive.

"You think you'll win?" He knocked my fist aside. Then tried to touch my face. I didn't bother to deflect him. Like with my hand, his fingers stopped almost a centimeter from my skin.

"My power isn't limited to my hands," I told him, "You literally can't touch me. Not unless I let you, or you completely wear me out."

I pulsed my TK Armor, pushing him back. Then I launched a trio punch right jabs at his nose, neck, and stomach.

Steps one and two were to be executed at the same time. To figure out how he fights, his physical abilities, and how he tended to use his quirk. At the same time, I wanted to rile him up. Keep him focused on me, and not thinking clearly about what I might have planned.

"You think you can beat me in an endurance fight?" he demanded.

"Considering your main experience is torturing a child who is too afraid to fight back, I think I can beat you in any way, shape, or form you might want."

He snarled, restoring his bleeding nose and ignoring the lesser hits to his throat and gut. Then he twisted out of his jacket and threw it at me. The second before it lost contact with his fingers, the coat turned into a pungent, yellow acid. Thankfully I had kept training my force field against water, so only a few drops made it through. My UA uniform jacket caught them, leaving it scarred. A fair trade considering how annoyed Overhaul looked when the majority of his attack only eroded the floor.

I tried to sweep his legs. But I telegraphed the move, and he jumped above it. He came down, punching at my head. His fist didn't reach me, but came closer. His lips twitched up. Good.

Then his attack skidded down the length of my body and hit the concrete. The next instant, the supporting rebar rocketed up, sharpened like spears. They stopped further away than his punch, but pushed me up into the air. And took more of my Energy than I was happy with.

I snapped one of them off, and launched it at him. Overhaul wasn't able to dodge it, and it dug an arc out of his side, before burying in the wall. He healed himself again. Then he darted to the side. I followed, but I could not stop him from reaching a red sedan. He slapped his palm onto it. The car seemed to implode. Only to form around him as a suit of fiberglass and steel armor. It was not an electric model, either, because the ethanol tank was flying at me. With a burning cloth hanging out of it. Presumably he had aerosolized the fuel and mostly sealed the tank. Because a moment later, it exploded. Not a huge explosion, but bright and with plenty of shrapnel, all flying my way. I hit it with a cloud of telekinesis, minimizing the impact I took. To be fair, one week earlier, before I gained Heat Resistance it would have hurt me more. Now? It didn't hold a candle to an angry Todoroki-kun.

[-10 Health, -15 Energy]

But I also didn't make it out completely unharmed.

I charged into the explosion, worried he might try to flee while I was blinded. I kept my Ki Detection active, so he couldn't try anything. Or his minions, if they managed to get past the Knights and Hadou-senpai. But he was attacking, too. Overhaul scowled more deeply when he saw I was visibly unharmed.

We exchanged a round of fisticuffs. I spent extra Energy on my shield, making it harder. I was trying to convince him his bare skin was more effective than the metal he had pulled from the car. It wouldn't change the third phase of my plan but if the fourth didn't work, the armor would make my backup plans tougher.

The fibrous plate over his heart cracked. Overhaul hopped back and clapped his hands. The car parts fell away.

"Did you really expect that to work?" I asked him, genuinely uncertain. But the lack of mockery seemed to make him madder. And I had the feel for his moves. Time to go.

I ducked, telegraphing an uppercut. He reacted, as expected. Followed me, aiming for my shoulder with a punch of his own. The angle was perfect.

"Disband party," I said quickly, timing it just right, "Party invite Kai 'Overhaul' Chisaki."

His eyes widened as the screen appeared in front of him. Right where I knew it would. Before he could stop, or even read the prompt, his knuckles passed through the 'Accept' button.

"Inventory," I said as I rolled backwards. I didn't need to dodge, because he had frozen in confusion and worry. Still, I acted quickly. I took out the new item in the first box. Then I took it out of its packaging.

"Dungeon Create," I stared up at him triumphantly. And reality changed around us.

It would have been white once, bright and clean. But now it was dingy and dreary. Mold broke up the grey stained walls. Dirt covered the windows, at least the pains that were intact. The few bedframes and curtains that remained were strewn about at random and also covered with mildew and dust. Some of the floor tiles were broken and all were at least a century late for a scrubbing.

We were in a hospital ward. But one that was long abandoned and left to rot. The type that people would have called haunted. Although here, calling it that might not be inaccurate.

Overhaul's eyes darted around wildly. Splotches appear on his neck and arms.

"What is..." he started to demand an answer but was cut off by a guttural moan from outside the room. A moment later it appeared in the door. A zombie. A decaying, pustulent, shambling corpse. It was more than I could have hoped for.

"AH!," Chisaki tried to suppress his scream. He made to reach for the floor. Then saw the shape of it and froze.

"Gondor Smash."

I cut the zombie in half. But the legs kept walking, and the torso pulled itself towards us. At least for a few moments, before it collapsed. It broke apart like other dungeon monsters, but there was a pile of ooze left behind.

"what is this? where are we?" Overhaul whispered harshly.

"In a nightmare of your creation," I didn't bother to lower my voice, "The psychospiritual manifestation of the bandage Eri was wearing when I found her. The pain and horror you put her through, given form."

For someone who hated dirt and germs, I couldn't think of a worse place. It was perfect.

"Party disband," I declared, watching him closely.

There were certain facets of the Dungeons that were not clear to me. Omissions from the manual. Things I could not test, at least not with my allies and friends. Like what would happen if I kicked someone out of the Party while we were in a Dungeon. Would it even work? If it did, would they stay in the Dungeon or get ejected? Or something else. Something worse. Even if the last option was the least likely, it wasn't worth the risk.

Except I could not have cared less if Overhaul was thrown into the ether instead of the real world. Or was shredded down to his atoms. Et cetera.

Fortunately, the first idea was the right one. Overhaul was still standing there, watching for more undead and starting to recover enough that he wanted to kill me. Except, he was holding back, since he didn't know what would happen if I died.

I checked, and he was indeed out of the Party. I wasn't prevented from kicking people out of the Party while inside a Dungeon. I already knew I couldn't add people outside the Dungeon, we had tested that both before and after the Guild was unlocked. I could seemingly add Guild members to the Party from anywhere in the world, but not from alternate worlds.

"Party invite Kai 'Overhaul' Chisaki."

I tested it, and the screen popped up. He reached for it desperately.

"Cancel."

I said, before he made contact.

"What are you doing?" he demanded. Then cringed when he heard more moans.

"I've thought a lot about how a prison might hold you," I told him, "And short of mutilation, I couldn't think of anything. Even then, if you figure out how to use your Quirk without your hands... With your feet or your tongue... But this Dungeon will hold you. It doesn't matter what you do here. Because you can't leave without me."

Crossing my proverbial fingers, I intoned, "Dungeon Exit."

Just like that, I was back in the garage. And he was not. I sighed in relief.

But there was one more thing. Or maybe two, now that I thought about it.

"Dungeon Enter," I said after picking up the bandage again.

I arrived to watch a zombie explode from Overhaul's touch. Even though the splatter mostly flew back, his pants and shoes were covered with goo.

That answered that. I could take people into dungeons, and come back for them later. And they could still move and act within the Dungeon without me. I wouldn't leave any of the Knights in a Dungeon alone, but it did offer certain training possibilities. Maybe three or more together would be safe enough. Maybe.

I walked over to him carefully. He heard me, and turned. Hope in his eyes.

"I knew you couldn't do it," he crowed madly, "You are infected with the disease of heroism, after all."

"Actually, there was just something I wanted."

I pointed at his head. The snaps on his mask opened, and it floated the two meters between us, into my hand.

"Dungeon Exit."

He lunged at me. But I was already gone.

I picked up the bandage. I folded it carefully, and put it back in the baggy.

"Inventory."

I tried to put it back into Inventory, as an extra precaution.

[Living animals cannot be placed in storage.]

The red flashing error alert confirmed one last question I had. If a person was in a Dungeon, they still counted towards Inventory's limit. Dungeon inhabitants did not.

I closed the screen. Then I looked down at the bandage.

"Analyze."

I pocketed the bandage. I walked over to the gap. My allies and the two yakuza turned to look at me. Squinting. I help up the mask so they could see it.

"holy shit," Rappa whispered.

I jumped down, and crossed the street. The yakuza drew back, and the Knights and Hadou-senapi let them.

"Where is Overhaul?" Tengai-san asked carefully.

"Gone," I said, "You'll never see him again in this world. Or do you think he just let me borrow this?"

I waved the plague mask at them. They both flinched.

"We're not here for you," Hadou-senpai told them, "We're here for Midoriya and Eri."

"You think we'll..." Rappa started to bluster, but Tengai put a barrier around them. The two of them, and also the SUV they arrived in. Then the man in monk robes pointed at his comrade's useless arm and open wound. The red-head relented. They retreated to their ride.

We let them go.


I was in Nezu's office, with the principal and also All Might. We were gathered around his desk, all looking at the packaged bandage.

After the yakuza duo left, I righted the van with Mikoto's help. All credit to our Support classmates and teachers, getting hit by Rappa and crashing through a wall only left the vehicle with only a few cosmetic dents and scratches.

Back at UA, Recovery Girl gave us all the standard check up for bugs, slow acting poisons, brainwashing, and the like. Then she provided a bit more treatment for Tsuyu and Cassandra. I led all of them back to the apartment Mom and I were using. Nezu had said he wanted to see me. But the rest of Knights stayed with our little flight risk. Sans All Might, who was not back at that point. Ochako, Tsu, and Momo chose to play a board game with Eri. Mom was working. Cass, Mikoto, Kyoka, and Ami sat down to watch TV. But they were all keeping an eye on my little sister.

All Might-sensei arrived in Nezu-sensei's office less than a minute after I did. Recovery Girl had checked and cleared him first at the principal's request.

"So he is trapped in there?" All Might-sensei asked, frowning thoughtfully.

"Analyze," I said. Then I pushed the screen over so they could see it.

"And he cannot get out?" Nezu asked.

"I don't think so," I told him, "System."

I went into the manual and showed them the Reflective Dungeon entry.

"It is a little vague," All Might noted.

"But reading between the lines," Nezu countered, "The only ways to exit are via someone with the Dungeon power, or to clear the final level."

"We have cleared the first level of many items," All Might recalled, "And there was never an exit other than Izuku's power."

"It is a quality four item," I added, "So it has between five and eight levels. And since my Dungeons can only go to the second level, he can't get to the bottom level. He can't get out. At least until I gain the Talent that unlocks its last level."

Then I looked at them sadly, "Which means I don't really dare get any Dungeon Talents after I gain access to the fourth level. I did this because I wasn't sure if anything else could hold him. But that's fine. If it stops him from hurting anyone else..."

"Actually, I have come up with my own plan for Overhaul," Nezu-sensei said, "I was thinking we would have to place him in a medically induced coma to implement it, but this works much better. If you will entrust me with the bandage, I will guarantee that if he ever escapes, it will be into another prison designed for him."

He explained to us what it was. I slid the bandage over to him.

"So long as you don't gain access to the fifth level in the next three weeks, we will be fine," Nezu told me.

"Then are we done here?" All Might asked. The principal nodded.

"Do you two have a half-hour or so to spare?" I asked, "There is one last thing, and I would like you both to see it."


I was facing Eri. Who looked frightened. All of the Knights, plus Hadou-senpai, principal Nezu, Recovery Girl, Eraserhead-sensei, Present Mic-sensei, and Advisory-sensei had formed a ring around us. Basically, everyone at UA who had fought the yakuza for her.

"Oni... Midoriya-san," Eri trembled, "I'm sorr..."

I held up my hand. I had brought back the bear. We had retrieved the hidden message. I would comfort her about that more later.

I knelt down and looked her in the eye, "You don't have to be scared, Eri. I'm not upset. You can still call me onii-chan, if you want. Rather, I have a present for you."

She blinked back her forming tears, and asked, "Really?"

"Yes."

I took out Overhaul's mask. She cringed. And I didn't hand it to her.

"I know you don't want this. That's not the present."

All Might came forward, carrying a heavy, wooden table. Really a slab of wooden with legs to be just above Eri's waist height. Mom came forward, carrying a small, half kilogram sledge hammer. Mikoto came forward, carrying three nails.

All Might set the table down. I placed the mask on it. Mikoto drove one nail into each strap and the third into the tip of the bill, locking the mask in place. And Mom handed the sledge to Eri, who could only just hold it up.

My sister's eyes widened in realization.

"Go on," I encouraged her, as the others stepped back.

Eri swung the hammer tentatively, lightly denting the gold beak.

Eri brought the sledge down more assuredly, cracking the reddish enamel.

Eri hammered the mask angrily, crushing part of it.

After that, she begin to swing more quickly and ferociously. On about the seventh swing, she started to cry as well. Shrieking from the effort and sobbing in between. A dozen more swings rendered the mask unrecognizable. She threw the hammer away and charged into me. She hugged me fiercely and sobbed into my chest. Mom caught the hammer with her Quirk, so it didn't accidentally hit someone else.

"It's okay," I held her gently, "He is really gone. He can never hurt you again."

Everyone waited, until she had cried herself out. She leaned against me, emotionally and physically exhausted.

"Do you want to keep that?" I asked, "We can seal it in a plastic block. A piece of art, to show that Overhaul was beaten."

"No," she said, "Thank you, onii-chan, but I don't want it."

"What if we burned it?" Nezu suggested. It had been one of my alternate ideas, but he took the initiative to protect her image of me.

She looked up at him. And nodded.

And we all watched as the little wooden table and the remains of the stupidly overdone plague mask were reduced to ash and bits of semi-molten gold (which Ami cooled with water and Mom pulled out so Eri wouldn't see them). Then Mic looked at the pile of ash, and the rest of us cleared the way.

"BEEEE GONNNNE!" he sang out, scattering the remnants on the wind.

For just a moment, Eri's lips twitched up.


Rappa tore off his mask, and dropped it in front of the seat.

"If Overhaul's gone, I don't have to wear that crap again," he muttered.

"You can't believe that," Tengai said. But he did not sound confident.

"Like hell I can't," the brawler argued, "You know there is no way in hell Overhaul would let the kid take his mask. Unless he was in no shape to stop him. And the mask wasn't even damaged, which means the kid probably wiped the floor with him."

Tengai had no response.

"So what are we gonna do now?" Rappa asked.

"Call in," the Barrier user answered, "Report what happened. I intend to head back to base once I am sure we were not followed or tracked..."

"If they don't already know where the base is after Monday," Rappa muttered.

"Of course I don't expect the same loyalty from you."

Except it seemed Tengai's loyalty was not needed either. The Hassaikai member he spoke with laid out the events of the day. The result of the police raid. The fact that all members of Overhauls inner circle, except for the two of them, had been arrested. As were most of the lower rank men loyal to Chisaki.

"The short of it is," the no-name told them, "We are through with you damn Villains, and happy to done with you. We are going to box up the rest of Overhaul's crap and send it to the cops. Hopefully, that will keep them from coming after the main base and the Boss. And now the Overhaul's idiocy is done and dusted, we can try to get the Boss some real treatment. So you two can do whatever you want. But if you show up at any of our bases, we will open fire and call the cops. Good day."

Then the line cut off.

Tengai looked defeated, but kept his eyes on the road. At least until a pool of inky blackness appeared in front of them. The front seats, passengers and all, were portal cut out of the car. Then the portal reversed itself. And a brick of det cord wrapped, C4 coated thermite fell on the accelerator. The SUV shot forward until it hit a building. Then the impact set off the bomb, ripping the smashed vehicle apart and melting large sections of the frame and engine block.


"The thermite they were carrying is presumed to have incinerated the bodies," Tsukauchi reported, "We found Rappa's mask, and it had his blood, so we know they were in the car at some point. But I'm not buying the accident."

"Good," the police commandant told Tsukauchi and Chief Tsuragamae. Then the older man's face hardened, "Neither of you is going to like what I have to tell you, but we need four evidence lots destroyed."

"Sir?" Tsuragamae cut his boss off, as he read off the evidence numbers.

"We figured out what Overhaul's goal was. And if it gets out... The best case scenario is Villains and mercenaries will tear that station apart to get it, and UA or wherever she ends up to get the girl. Worst case scenario? War. And I'm not even exaggerating a little bit. Other nations would invade Japan, either to control this secret or destroy it. Everyone here who knows has agreed to submit to memory erasure, so we can't leak it. I will tell you, if you will agree to the same. If not, you'll just have to take my word and destroy it."

"Sir," they both saluted, shaken by the how tired and afraid the commandant sounded.


The seats screeched to a halt, scraping the already heavily punished wooden floor. Before they could react, the man with silver hair touched their seatbelts. Which rotted away to nothing. Tengai held his position, looking at the people surrounding them. He recognized the stone haired young woman as someone who had approached the Hassaikai about purchasing Trigger. She was turned away when she asked for too much, and wanted it uncut.

"What the hell is this?" Rappa demanded, but less angrily than he might have. Even he could read a room, sometimes.

"We heard you might be out of a job," Decay told them, "And when we found you, you were doing pretty good against the brats. But you were also smart enough to cut and run. So call this an interview."

"And if we aren't interested in your job?" Tengai said.

"Well, an interview does go both ways," Harley told them, "You might want to find out if you want to hang with us, before you flat out say 'no'. No-mu that is."

"Because one way or another," Shigaraki informed them, "you two are now part of the League."


"Midoriya-kun, Midoriya-san, what can I do for you?" Nezu asked us.

It was Thursday, after class. The previous night, after Eri fell asleep, Mom and I had a long talk.

"First, party invite, Principal Nezu," I said. He accepted.

"Now that that is out of the way," Mom said, "The reason we are here is that I would like to accept the job you offered me Tuesday, provided you can meet four conditions."

"And those would be?" he studied Mom but glanced at me.

"The first condition is that we will be staying here on campus, in a slightly modified version of the apartment you arranged for us, until the dorms are complete. The second is that whatever dorm mother suite you build for me will have one additional bedroom."

Nezu smiled slightly.

"The third condition is that you will arrange for Eri to stay with us. Arrange it with the police, Child Services, and whoever else we need. And the fourth condition is, if nothing has changed in a year, you will arrange for Eri to be adopted by me."

"And by nothing has changed..." he prompted.

"If you find Eri's parents and they want her back. Or if Eri decides she doesn't want to be my sister and Mom's daughter," I said.

"Are you sure?" he asked carefully, "You only met her six days ago."

"We will never give up on that girl," Mom said with the same fury she displayed that time my fourth grade teacher told her I should expect to drop out after middle school, "Not so long as she needs and wants us."

"And probably not even if she doesn't," I added, "Though we might have to do it from afar in that case."

"Your terms are acceptable," he smiled, "More than acceptable."


SEVENTEEN YEARS LATER

There was a pulse of energy and then a displacement of air. The long dormant machines detected it. They spun up, and started to scrub the air. The pod was already maintained at 15 degrees centigrade, for the other machines. But now the air conditioner would need to work harder.

Thin. Stubble on his face. His hair jagged and longer than he liked. His clothing replaced by little more than plastic sheets.

Chisaki Kai realized he was floating. In a cubical room, seemingly free of gravity. But a familiar strip of cloth, one burned into his memory, floated next to him.

Three of the walls were flat, unadorned white plastic. Two had windows. And the last had a variety of doors and panels.

Then a projector started. A 3D hologram appeared. He recognized it as the leader of that school for Heroes.

"If this message has been activated, that means the air in the pod has been displaced. If you are not Chisaki Kai, then I warn you to leave this pod or destroy it. It houses a criminal monster."

"However, if this is, as it should be, Chisaki Kai, congratulations. You managed to not only survive the Dungeon, but escape it. Also, I suppose, congratulations from past me to present Midoriya-kun, for unlocking that depth of dungeons."

"You may be thinking of Overhauling this prison. I suggest you look out the window, first. Depending on how long you took to escape, you are seeing either the empty void of interplanetary space, or looking down on the surface of Venus. That is correct, you are in a special module on the Cupid probe. And if you alter it, the module will be both ejected and the air evacuated. Though I do hope you try, if you are at Venus. Observing you attempt to Overhaul the atmosphere into something you can survive would be quite informative for future terraforming efforts. At least until you run out of energy or hit the ground. Unfortunately, the pod was not built for re-entry."

"You might be wondering how you will survive. The pod is already self-cleaning, to avoid contaminants interfering with any systems. The air and temperature are kept survivable. There is a week's supply of preserved food and water in the unit below this projector, and a space toilet to the right."

"Of course, one week of food is nowhere near enough. But as implied by the self-cleaning, all waste is gathered in a receptacle on the left. With your Quirk, it is a simple matter for you to convert your urine, feces, dead skin, and hair, back into something edible."

The hologram's eyes narrowed and glinted, "That's right. I'm telling you to eat your own shit, or die."

The Nezu's projection forcibly relaxed and straightened his tie, "On a personal note, I have no patience for anyone who experiments on other sapients. I personally would have assured you received the death penalty, had Izuku not come up with a far better punishment for the likes of you, and inspired to create this backup. So goodbye, Chisaki Kai. Enjoy your own personal hell, version two. Or kill yourself. I don't mind either way."

Author's Note: And so ends the Shie Hassaikai arc. Other than a bit more wrap up in the next chapter, which will continue the Internship arc. But first back to the other story, and I hope to alternate between them for the immediate future.
