"nighteye and lemillion are down that hall over there." I yell over to them as I point to the hole in the wall. I turn my attention to Eri. I run over to her, but a few seconds before I can reach her, a pillar comes up underneath, flinging her into the air. I flip my souls gravity and basically fly toward her.

"Chisaki!" Midoriya yells as Overhaul makes a pillar underneath himself. Midoriya begins to climb up the pillar, I can't use soul magic on him, the way I'm going, I'm going to be on the floor, unable to move. 

"eri!" I shout, I lock eye contact with her for a second, she looks away with a slight amount of guilt in her eyes. As the pillar, along with myself, continues to rise, I notice Lemillion's cape rising next to the peak, it was stuck in a slightly erratic dance. I grab onto the small ledges of the pillar and push myself along to give me a sort of boost. I'm still not fast enough! I'm moving at roughly the same speed as the pillar, I'm not getting any closer!
I can't use my blasters either without the risk of hitting someone. I'm about 15 meters behind them, Midoriya is about 7 meters behind me.
I jerk to the side as I reflexively dodge something, after a second glance, I realize it's Nemoto. He's back to his normal self. As I continue to climb, I notice Lemillion's cape is lying on the edge of the pillar, no, wait, Eri is holding it. "eri, jump! i'll catch you i swear!" I shout, I notice her stand up. Then, she jumps. Falling closer, closer and closer. As soon as she's about half a meter away from me, I change my soul's gravity back to normal. We really don't want a head on collision here. She falls into my arms. Everything slows down for a second. I catch a slight amount of light growing in her horn, it must be some part of her Quirk. "i've got you, kiddo." I muttered.

"Give her back!" Overhaul yells, snapping me back into reality. Sharp pillars begin to sprout out of the original, I dodge as best as I can it's more important Eri doesn't get hurt. Midoriya is about a meter away, maybe if I can get to him. I land on one of the spikes and jump backward toward Midoriya, reaching back to him with my free hand.

"shortcut!" I shout, he seems to realize what I mean, then jumps off, I feel something run into me and send us flying into the air.
What?
I glance over to Midoriya, who is hanging on by a thread, his leg seems to be broken. He used 100%, didn't he? I use my legs to pull him closer so the landings smoother. "hold on, i can get us down." I say, as we shortcut to the ground. We land on the ground, I feel a slight pain growing in my chest. I sit Midoriya and Eri down, and go to inspect Eri. Just as I do, I notice my injuries are all gone? I look over to Eri, her horn is glowing brighter than before. Then I remember her Quirk, it's rewind. That's how she healed me. "eri, could you touch his leg?" I ask, Midoriya gives me a slightly confused look, Eri places her hand on his leg. Midoriya's leg reverts to the way it was.

"Is this... your power?" Midoriya mutters, kneeling in front of her, Eri looks slightly scared. Is she afraid of her own ability?

"her quirk, it's rewind." I say, Eri lets him go. "anyway, i have a plan. overhaul will be coming for us any second, and we don't have the time to escape. you and i have a good combination of quirks to be able to take him down. and with eri's help, you should theoretically be able to fight at 100% for quite a while." I say, Midoriya's eyes widen but then flinches slightly as he grasps his stomach.

"Wh-What's happening? It feels like my body is being pulled apart from the inside. "Midoriya says in a pained voice. Is this why she fears her Quirk?

"She has no control." Says the distorted voice of Overhaul. The ground begins to cave in, Midoriya grabs Eri, and we run into a clearing. "She may have activated it at a good time, but she doesn't know how to stop it. Isn't that right, Eri?" The dust in the air slowly falls, revealing a very mutated looking Overhaul. "She rewinds humans. That's who Eri is. Depending on how you use her, it might even be possible to turn a person back into a monkey. If you keep carrying her like that, you'll be annihilated. Everyone who touches her will be rewound into nothingness. That girl's Quirk is cursed. Hand her over. There is no way to stop her other than to disassemble her. Unless you want to be annihilated, hand Eri over." Overhaul says, Midoriya grabs Lemillion's cape and ties it tightly around him with Eri sitting in it.

"Never." Midoriya says.

"you won't be getting eri. the only thing you'll be getting is a cold cell following beatdown." I say.

"You're Quirk is such a blessing, Eri!" Midoriya says to her, tears well up in Eri's eyes. Midoriya activates  One For All, the ground around him begins to crack from the pure power. A greenish teal aura forms around him, and his hair and eyes glow a vibrant green. "Eri, will you lend me your power?" Midoriya says.

"let's do this." I say, Overhaul places his multiple hands on the ground and charges at us. Spikes speed toward us, I teleport next to Overhaul on a nearby building. Midoriya just appears on the other side. He's moving so fast that I can't even see him, Midoriya kicks the villain high into the sky. Keeping damage to a minimum, quick thinking Midoriya. I teleport up to Midoriya, summoning a blaster underneath me to keep me from plummeting to the ground. "her quirks increasing it's output, get to breaking those bones." I say summoning more blasters, bones won't be much help. To be honest, do I really need to be up here? This man is about as strong as All Might, I'm honestly up here because I don't want to just watch. Overhaul is rebuilding his body, Midoriya begins to fly around at a speed which I can't be bothered to try keep up with. Instead, I continue to blast Overhaul and hold his soul up off the ground. I get a shiver down my spine as I feel a familiar feeling, although it's different, instead of holding bits of souls mushed together, it's multiple full souls closely compacted in one body. I get rid of my blasters for two reasons. One, they weren't really doing much, and two, this is Midoriya's moment I don't want to spoil that. It's also like a key point in the storyline, I mean-- it's important for him, so I won't intervene.  

"If I can't save... the one small girl in front of me... how can I become... a hero who saves everyone?" Midoriya screams as he lands the final hit, I let go of Overhaul's soul, making him fall out of the sky toward the ground, that, along with the pure force of Midoriya's punch, brings everything crashing down.
I pull a ton of bones out of the ground where Overhaul lands to make sure he doesn't move. I teleport to the ground a few meters from Midoriya. Eri's Quirk is still activated, we need to deactivate it. Where's Dad-- Aizawa? I look around and see Nighteye and Uraraka sitting on the ground nearby.

"we need Eraserhead now, he needs to deactivate eri's quirk." I shout over to them.

"Eri, are you hurt--" Midoriya begins, almost on cue, his teal aura is replaced with a yellow one. Eri's Quirk is getting too strong for his body to handle. Midoriya falls to his knees.
I jump back to avoid getting too close. Overhaul's hand reaches forward and crushes Midoriya, Eri and me, but before it can do anything major, Eri's Quirk reverts his body. The villains he was merged with are flung away. Uraraka jumps in and restrains Overhaul. Ryukyu begins to climb out of the crater with some other heroes, including Aizawa and Nighteye.

"aizawa, use your quirk on eri and midoriya!" I shout over with an urgent tone. Froppy lifts Aizawa's head, it must've been that other guy's Quirk. Eri's Quirk turns off, she collapses, Midoriya lifts his arms and holds her. At least they're ok. I feel like I'm forgetting something... Wait, Frisk! I Quickly shortcut back into the crater and looked around, soon finding the bones that held them were falling apart. The only ruminant of them ever being here is a calving in the wall.

"Until next time, comedian =)" It reads, damn it! I glare at the writing, I should have come back! I should have focused on what was in front of me! And now they're gone! I want to find them, but I can't without being suspicious, or at least more suspicious than I already am. Lemillion probably noticed some sort of connection between us which makes problems. I sigh as I massage my temples, then another thought pops into my head. I pause time and look around, after about a minute, I find what I'm looking for. The bullet Lemillion was shot with, I rip off some of the more thick fabric off my pants and wrap it around the bullet, then place it in my pocket. I un-pause time and shortcut back to everyone else. The ambulances are here along with the police, I go around and help to restrain some of the villains. But there's still no sign of Frisk, they got away... It's fine, they're always another time...
