A little while earlier, before Izuku burst through the wall to find Danny and Mirio, he was back with the other pro heroes and police. The main detective said, "The walls have finally stopped moving, but it's hard to tell where we are now."

Nighteye replied, "I'm positive Eri's bedroom is located in that direction."

The detective shouted at Mimic, "Irinaka! I want you to straighten out these hallways again, you hear?"

But Mimic didn't do anything. Aizawa deduced, "The drugs must've worn off. Looks like Fatgum knew what he was talking about. Irinaka's power: it's back to normal again."

The detective said, "Guess that's good news. But that was Toga and Twice just now. The League of Villains is here, too."

Mimic growled, "Toga and Twice. I won't forgive you! You traitors will die!"

Nighteye said, "Tell us where the other League members are hiding."

Mimic shouted, "I don't know! But I'll find every last one of them! I won't stop until I've crushed all their skulls to dust!"

Nighteye sighed, "I'm guessing those two are the only ones here. At least for now."

Rock Lock muttered, "Why are you fools standing around talking instead of acting?"

Izuku asked, "What do you mean?"

Rock Lock answered, "The cops can deal with the League. You're wasting time, so ignore them and keep on moving. Or did you morons forget our mission's top freaking priority?"

The detective said, "He has a point. That would be for the best."

Rock Lock sighed, "I'll hang tight. Someone has to stay behind and keep an eye on Irinaka. And thanks to the crazy girl with the knives, I'm not going anywhere anytime soon. Well, go on! Finish what we came here to do. Ryukyu and the other heroes up top. The cops we got separated from down here! Suneater! Red Riot! Fatgum! Lemillion! Phantom! They're all still fighting for us! You gotta know that, right? We worked too damn hard to fail that girl now. So go on!"

Everyone nodded and started running off. Izuku shouted back, "We'll find her! And we'll save her! Don't worry, Rock Lock."

Rock Lock smirked, "So you're promising to save the girl. Then you better do it, Deku! Same goes for you, Nighteye! Her future is on you."

As everyone was running, they didn't notice that Toga and Twice were hiding above them. Twice said, "And they're off. Our best plan of action would be to make a break for it immediately. What should we do, Toga? Kiss maybe?"

Toga answered, "There's a good chance Izuku's gonna get bloodied up. I'd really like to see that again. Plus, if that ghost kid bleeds that weird blood, I wanna collect that, too. But, maybe more than that, right now I wanna make Overhaul cry like a little baby."

Twice replied, "In that case, I've got no idea! Here's what we should do."

Toga turned to Twice, "I'm listening."

Twice whispered his plan in Toga's ear. After he was done, Toga giggled, "Oh, that's perfect, Jin. It'll make Tomura real happy, too! If Izuku's group and Overhaul come together, everybody's gonna end up bruised and bleeding. The fight between the heroes and the yakuza will be epic! I bet at the end of the battle, both sides'll be super messed up. Oh, I wish I could watch!"

Back to the present, after Izuku kicked threw the wall and punched Overhaul, Aizawa and Nighteye jumped through the hole Izuku had made. Aizawa quickly activated his Quirk to erase Overhaul's. He turned to Nighteye, "Nighteye, quick! Secure those who've been injured."

Nighteye took in the scene. He looked over and saw Phantom standing in front of Mirio, who was looking worse for wear. He ran over to them.

Mirio muttered, "Get Eri out of here. She's behind me."

Phantom added, "Mirio's been hit with one of the Quirk bullets. He's in bad shape."

Nighteye grabbed Mirio, "Rest. I've got you now. You were amazing. You found her, Mirio." He turned to Phantom, noticing he wasn't at his full strength, either. "Fenton, thank you for protecting them."

Chisaki growled, "He took away my power!"

Izuku and Aizawa charged in. Aizawa said, "Phantom already has him backed into a corner. We need to join him and finish this!"

"Yes, sir!" Izuku shouted.

Chisaki mumbled, "It's time to get up, Kurono."

Aizawa noticed and threw Izuku towards Phantom, getting hit with one of Kurono's skewers. He said, "Those pierced by the long hand will find their movements slowed. I meant to skewer both of you at once, but, hey, that's heroes for ya. And I know I can't hit the ghost hero. Even if he's been weakened by Chisaki's attack, he's still too quick."

Chisaki stood up, "It took him long enough to wake up. Those two schoolboys managed to take Kurono out. But I repaired his head and healed the damage while the two were distracted."

Phantom said to Izuku, "Be careful. His Quirk is good. And he's faster than I thought he was."

Izuku noticed Phantom panting, "He got you?"

Phantom nodded, "Yea. Took a lot of my energy to heal myself. Be careful with close combat."

Izuku charged in, "I'll just be faster than him!"

Aizawa couldn't hold his eyes open anymore and had to blink.

Chisaki said, "Everything, all you've done has been for nothing!"

Phantom shouted, "Izuku, watch out!"

Chisaki's Quirk activated and he created several spikes. Izuku dodged them as best as he could. Phantom turned intangible while Nighteye jumped out of the way with Mirio and Eri.

Chisaki sighed, "As if I'd let my plans be ruined by people like you who are sick in the head. You get it, Nemoto. You want me to succeed. I won't allow all of my hard work to end here. You've always been eager to help. So I know you'll happily give your life for my cause, won't you?" He walked over to Nemoto and put his hand on him, while activating his Quirk. "I'll be a good sport and acknowledge that you boys were stronger than me. Even you, Lemillion. I respect your perseverance. But in the end, I will still be the victor. Now, heroes! I'll have you return Eri to me!"

Kurono grabbed Aizawa and dragged him to the floor below. He struck him a few more times to slow him down. "We referenced your Quirk quite a bit while conducting our research on Eri. So I know a great deal about you, Erasure Hero. Fortunately, I was able to isolate you from your friends without resorting to lethal force. You'll be much more useful to us alive. Erasing Quirks. That's an ability Overhaul finds very appealing. Oh, stop struggling. It's no use. You have all the speed of a snail right now. Give up. I struck you with the short hand. You won't move normally for another hour. There's no stopping him once he's set his mind on something. I don't know how much you've been able to find out, but Eri is the Hassaikai boss's granddaughter. If it brings Overhaul closer to achieving his goal, nothing is off limits. He will use anything and anyone. That's the kind of man he is."

Up above, he successfully merged with Nemoto and became a terrible looking monster. Izuku was stunned. Phantom cringed, "OK, he's definitely into crazy fruit loop territory."

Chisaki sighed, "That was unpleasant but necessary, and I feel much better now. Cleanliness is an obsession of mine. When someone contaminates me with their filth, I lose control. It's never gone quite this far before, though. What an unfortunate turn for you, Lemillion. You chose to get involved with Eri, with me. And now your Quirk is lost forever. If you'd only backed down sooner, you could have held onto your pathetic dreams. But instead you fought, refusing to give up, even after your Quirk was gone. And now, thanks to your heroics, your friends will die along with you!"

He charged at Nighteye, Mirio, and Eri, but Phantom flew in front of him, "Guess again, fruit loop!" He charged his hands with ecto energy and blasted Chisaki across the room.

Izuku charged towards Chisaki and hit him with one of the spikes, grazing his arm.

Chisaki created more spikes to send to Izuku, who dodged. "Power and speed. That's all you've got, boy. And you, ghost boy, I know you're scared to fight close combat against me, since I've already grazed you once. You seem to have healed. But how much did that take out of you? And you even haven't used your strongest attack against me? That powerful scream I saw you use in the fight with All Might. You don't have the energy to use it on me, do you?"

Phantom growled, but he knew that Chisaki was right.

Nighteye charged in, "Stand down, Deku, Phantom. I'll deal with him."

Chisaki chuckled, "Will you now?"

Nighteye shouted, "You two look out for Lemillion and Eri."

Izuku nodded, but Phantom was unsure. Nighteye turned to Phantom, "That's an order, Phantom. Stand down."

Phantom sighed, "Yes, sir."

Nighteye launched some of his support items at Chisaki, who dodged them. Nighteye demanded, "What happened to Eraser Head? Did your lackey take him somewhere?"

Chisaki chuckled, "I'm interested in heroes who can erase Quirks, so he's been shown to the VIP room."

Nighteye replied, "You destroy other people's Quirks so cavalierly, but when the tables are turned, it frightens you. If Lemillion's Quirk is lost forever, does that mean you perfected the bullets and used one on him? You deployed your prized weapon instead of sneaking it off to safety. Were you that frightened of my protege?"

Chisaki tried to attack, but Nighteye used Foresight to dodge all of his attacks.

Meanwhile, Izuku and Phantom went over to check on Mirio and Eri. Izuku asked, "How badly are you injured? Do you think you can walk?"

Mirio sighed, "Yeah. No problem. I'm fine. But I failed. You're sad again and it's my fault."

Phantom said, "Dude. You did amazing out there. I should have done better. If I didn't get hit, I would have protected you from that bullet. You didn't need to protect me."

Mirio smirked, "I'd do it again."

Izuku said, "Come on. Let's go." He then punched a hole through the wall. "I'm pretty sure this'll lead us back. We need to get away from Chisaki!"

Phantom added, "I should go and find Mr. Aizawa. I can phase through the floors…."

But then Eri interrupted, "No. That's enough. I'm so sorry."

Suddenly they heard an awful sound behind them. They turned around to see Nighteye being stabbed with a spike right through his abdomen. Nighteye tried to use his Quirk to see if the boys behind him got out safely, but all he saw was blood."

Izuku was pissed. He charged right at Chisaki, who created spikes to defend himself, but Izuku crushed all of them.

Chisaki was shocked, "He seems much more powerful now. Was he only fighting at half strength before?"

"She's not the only one." Chisaki was suddenly punched hard by Phantom, who charged in when Chisaki was distracted. He turned back to Mirio and Eri, "Take her. Get Eri to safety!"

Mirio nodded and led Eri away.

Izuku's arms and legs were aching, but he could still move. He activated One For All at 20%.

Phantom also knew that he was low on energy, but he would burn through all of it to stop the monster in front of him.

Chisaki said, "Give up. I've already told you how this ends. You're all going to die!"

Izuku shouted, "You're wrong! I won't let that happen!"

Phantom added, "I'm already half dead. I won't let the other half of me die today. No one else is getting hurt today because of you. Not on my watch!"

Izuku noticed what Phantom said, but kept talking, "Even if it's already been decided. Even if it's set in stone. I'll smash that future!"

Phantom added, "I've already proven that the future isn't set in stone. I can beat this one too!"

Both boys charged in. Chisaki was pissed. "You brats!" He sent spikes towards them. Izuku dodged as best as he could, one of his arm bands crumbled to dust. Phantom blasted Chisaki with an ecto blast, but Chisaki was still moving around.

Izuku blasted to the ceiling, then blasted himself down towards Chisaki, "One strike to the head! Manchester Smash!"

But Chisaki dodged, "You may be fast, but compared to your comrades, the lines of your movements are painfully easy to predict." He created several spikes, some of them hit Izuku.

"NO!" Phantom shouted as he charged in and punched Chisaki away. He rushed to Izuku and phased him out of the spikes, luckily only his arms and legs were hit. "Izuku, I'm sorry."

Izuku shook his head, "It's OK. I wasn't fast enough."

Phantom quickly put ecto goo over Izuku's wounds as Chisaki stood up, putting himself back together as Phantom had blown parts of him away. "Being able to put myself back together again doesn't make breaking apart hurt any less. You're done. Both of you."

Izuku shook his head, "No way. It's not over."

Chisaki sighed, "Just like your friend. He didn't know when to give up, either. Though there's something to be said for a person who refuses to admit defeat. Someone else is about to die because of you! Is that what you really want? Eri?"

Phantom growled, "Leave her out of this!"

But then they heard Eri's small voice, "Wait. It's not….I don't want this!"

Izuku and Phantom turned to see that Eri had left Mirio and came back. Izuku shouted, "Go back! You need to stay with Lemillion, Eri!"

Chisaki taunted, "Eri. Look at him. Injured. You don't really think this one can defeat me, do you? What about the ghost boy?"

Before Eri could answer, Phantom flew over to her and stood in front of her. He then said in a dark, eerie voice, "That's enough. Eri is not yours. She's her own person. Your days of manipulating her are over. You think you've won because you're using her fear of you to bring her back. She's never going back to you. Ever. Not on my watch."

Eri muttered, "Danny Phantom."

Chisaki laughed, "And you think you can stop me? All I have to do is destroy you in one swipe. I bet you don't have the energy to heal yourself again. And you don't have the energy to defeat me. Neither of you do."

"You're wrong," Izuku interrupted. "I won't let Eri down, even if she doesn't want my help. I'm not letting anyone die! I'm going to save you!"

Phantom turned to Eri, "Besides, I did give you a pinky promise."

Nighteye was shocked at what he saw. He had foreseen everyone dying and Chisaki getting away with Eri. But the future seemed to be changing. He looked over at Phantom, and saw a vision of Phantom glowing with energy, and wearing a peculiar ring on his finger.

Suddenly, the ceiling burst open and Ryukyu burst down with Ochaco and Tsuyu, ready to fight.
