--- at the U.A. evacuation centre, the Shiketsu school route ---

"Why aren't we moving?" a young man asks as he looks around at the robots that are preparing to transport them. 

"Get us moving!" an old man yells as he looks at the security cameras. 

"Mom, Sis-" Natsu says as he looks at the live news feed being displayed on the projection screen, "don't get separated". 

"I heard Mt Lady and the others lost" a white haired boy says as he watches the fight on his phone. 

"No way! It's fake news!" a blonde haired boy says as he balls his fists. 

"What happened?" a man with a blue cap asks as he looks at his friend. 

"We believed and left it to them, but for it to end up like this..." his friend says as he grits his teeth. 

--- on the ground where Izuku and Tomura are ---

A wind funnel surrounds the two of them as green lightning strikes the ground around them. Izuku growls as he grips onto Tomura's wrists, Tomura smirking as he chuckles slightly. 

--- where the police hideout is ---

"We're still uncertain about the full damage we received" a police officer with glasses says from behind Tsucauchi. 

"All For One is heading East!" a man next to Tsucauchi says as he watches All For One's movements. 

"Aiba! What's the situation?" Tsucauchi asks as he turns his head to look at La Brava. 

"I've already taken control of U.A.'s evacuation system" La Brava says calmly as she types on her keyboard, "you see how some of the blocks are already moving? But... there's a block that's being stopped from the inside. Someone's made it stop". 

--- in the underground of the Shiketsu evacuation block ---

All For One told us to follow Skeptic. But we've lost contact! What should we do? We need to show All For One results. Once the day ends, the world will be All For One's! If we don't give him results, our lives will be... 

A traitor says as he goes to break down the power to the block. 

"Found him!" Gunhead shouts as he runs around the corner. 

The traitor puts his hands on the machinery as he sends out an electrical current which stops the block from moving. The block shakes as everyone stands as still as they can. A large piece of rubble stats to fall, heading for a group of people. 

"Tetsutetsu!" Kendo yells as she looks over at Tetsutetsu. 

"Right!" Tetsutetsu says as he runs over, hardening his body, when suddenly, the rubble stops falling. 

"Even though I know what happens next... even though I know the same thing will happen again... what the heck?!" Death Arms says as he holds the rubble up, "my body's... moving on its own, too!". 

--- where the police hideout is ---

"Blocks 17 to 32 have restarted!" a blonde haired man shouts from his computer. 

"All For One has passed the skies above Ido city!" the man next to Tsucauchi says. 

"Who can still fight?" Tsucauchi asks as he turns around to look at the woman tracking the heroes' progress. 

"We've put out a call to various groups, but everyone's wounded" the woman says as she looks at Tsucauchi. 

Suddenly, the man next to Tsucauchi falls to the ground in terror. 

"What now?!" Tsucauchi asks as he looks down at the man. 

"This is bad... the heat... in Gunga... Dabi's heat..." the man says as he points to the monitor. 

"What about it?" Tsucauchi asks as he goes to the man, kneeling down, "report! Was Endeavour defeated?!". 

"No, not yet... but... our analysis is concluding that he will be!" the man says in complete shock, "even since Dabi was captured, he's been storing up heat. He's been compressing it and storing it up! At this rate, in about ten minutes... or even less, he'll annihilate himself... and the energy freed from that pressure will cause a high pressure explosion that will burn up everything within about 5km!". 

"Right now, within about 5km of Dabi's location lies the evacuation path that connects U.A. in the East and Shiketsu in the West" La Brava says as she looks at the map on her screen. 

"Does Dabi know this?" Tsucauchi asks as he looks at La Brava, "no, there's no way... but if he received information about the evacuation route from Skeptic back then...". 

"Contact them! Immediately!" La Brava shouts as she turns around to look at Tsucauchi, "there are still blocks that can be stopped before they enter the predicted damage zone!". 

--- in the evacuation block where the Todoroki's are ---

Parts of the roof continue to fall in as Natsu pulls Fuyumi and Rei towards him, doing his best to protect them. 

"Open the emergency hatch!" Gunhead orders as he throws his arm out, "get to the surface!". 

--- where the police hideout is ---

"Tsucauchi-san! All For One is accelerating!" another man reports as he looks at the speed of All For One, "he's about to reach the estimated effective range of the Sludge Warp!". 

If the two demon lords are in the same place, then there's nothing we can do... 

Tsucauchi says as he starts to think of the possible outcomes of this situation. 

"What about backup?" Tsucauchi asks worriedly. 

"There's no one" another man says as he shakes his head, "even if there are still uninjured heroes around, none of them will make it in time". 

"Tsucauchi-kun" All Might's voice says as the voice comes from the radio on the desk. 

--- at Camino Ward ---

"Todoroki-kun, you haven't recovered from Phosphor yet-" Tenya says as Shoto tries to get up. 

"I said, I'm fine" Shoto says as he stands up, "All For One's going to get Koko and Midoriya. I can still move!". 

"You have enough on your mind just worrying about your brother" Tenya says as he puts Shoto's arm around him to help him walk. 

"I have to do... what I can..." Shoto says as he starts to limp. 

"It must have been so hard for you to face him like that..." Tenya says as he looks at Shoto, "it must have been heart breaking... you're the one who kindly told me to look at who I wanted to be. Why do you have to suffer like this?". 

The two of them look up as sparkles appear in front of them, Koko forming. 

"Koko!" the two of them say happily. 

"Shoto! Tenya!" Koko says as she runs to the two of them, hugging them both tightly as she kisses Shoto's cheek, "are you alright?". 

"Why are you here? You should be with Midoriya and Bakugo" Shoto says as Koko helps hold him up. 

"What's the situation? Why have you moved again?" Tenya asks as he looks at her. 

"Dad and Mic were taken by Kurogiri alongside the real Koko" Koko explains as the two of them realise this is one of Koko's clones, "Izuku threw Tomura out of the coffin in the sky and is now fighting Tomura on the ground". 

"What about Bakugo?" Shoto asks as he looks at Koko. 

"Tomura... got him" Koko says as she looks down, Tenya and Shoto gasping, "but Edgeshot is doing everything he can to save him. Koko made clones of herself to come and help everyone. She sent one to Gunga, one here, to you two, and one has stayed behind at the coffin in the sky. The real Koko is with her Father, Present Mic, and Kurogiri. I don't know their location". 

There is a crackling noise in their in ears. 

"Oh, it connected!" Tenya says as he puts his hand up to his ear. 

Thank God for that! Are you two still okay?

All Might asks through their in ears. 

"All Might?" Shoto questions as he looks at Tenya. 

There's no time, so I'll keep it short. You two need to run to Gunga right now. Dabi's about to explode, and an evacuation block is in the blast zone. Right now, Endeavour's keeping an eye on Dabi, but he can't stop the explosion with his Quirk. Young Iida, I know you can run. Young Todoroki, the body and mind are part of one unit. You should understand this after everything you've been through. 

"All Might, but All For One is-" Shoto says as he puts his hand to his ear. 

It's okay, we still have someone strong in the wings! If you fight still carrying your doubts, then you can't win against that. After all your worrying and doubts, what you decide in your heart is priceless. Stop Touya and give everyone some peace of mind. So that you can be you. Right now, the only things that can do something about crisis at Gunga are Engine and Half Cold Half Hot. You two are our only hope! We're counting on you. 

"All Might, I'm here, too" Koko says as she puts her hand up to her ear, "I don't have time to explain but I'll go with them too. I know Father is heading your way, I can feel it. Look, another one of Koko's clones took All For One's portion of his Quirk. He's heading your way with only the embers of All For One remaining and Rewind killing him slowly. He'll think the diminishing All For One is because of the Rewind, so make sure he doesn't find out. I'm sure Koko will be feeling the effects of having double the All For One Quirk now. I'll head to Gunga with Tenya and Shoto and then I'll report back to you. All Might, please... don't die before you sign Izuku and Katsuki's cards". 

Stay safe, you three. 

The line disconnects as the three of them look at each other. 

"Run? But your Engines are stalled and Gunga is so far away..." Shoto says as he looks at the different buildings covered in ice around them. 

"The rain's cooled down my legs nicely" Tenya says as he puts his mask onto Shoto, "I can run. I can!" he says as he lifts Shoto onto his back, Koko wrapping vines around the two of them as she makes herself weightless, "Todoroki-kun, my legs are here to guide lost children". 

"For the sake of others..." Stain says as he watches the three of them. 

Tenya takes off, running as fast as he can as Shoto and Koko hold on tightly. 

--- where All Might is ---

We're leaving it to you, Young Iida, Young Todoroki, Koko. 

All Might says as he puts his phone into his pocket. 

"Next, it's my turn" All Might says as he looks at the bright light of All For One's Rewind heading towards him. 

His phone rings as he takes his phone out. 

AM: Tsucauchi-
T: You idiot! What were you thinking?! 
AM: This is fine, Tsucauchi-kun. This was my fight in the first place. It brings back memories... of our long battle... 

All Might hangs up the call as he picks up his briefcase. 

"I heard Shigaraki's hatred has affected you" All Might says as he puts his arms out, "then, you can't ignored me, can you? That's right. You can't ignore me. Why?" he says as the briefcase opens, the car hood doing the same as different pieces of metal attach themselves to All Might, "because I am here!". 

--- 2km away from the Gunga site ---

Everyone walks in a line as the heroes guide them to the evacuation cars. All anyone can see is the large ball of Dabi's flames quite close to them. Fuyumi, Rei and Natsu watch on, knowing their family is in there, fighting. 

"Touya..." Rei says, her breaths heavy. 

--- Gunga site ---

There is a large explosion from behind Endeavour as he runs away from Touya, doing his best to guide him away from people so no one else is hurt by his son. 

It's not just the evacuation block... Pixiebob and the others who are keeping Toga and her clones in check right now are... oh no, I'm starting to feel the damage from the fight with All For One in my legs. I can't lead Touya much further... 

Endeavour says as there's another explosion from behind him as he turns around. He looks up at Touya who is screaming in anger and frustration. 

"D-Daaad!" Touya groans as he looks at Endeavour, "loook...". 

Touya screams as he throws a large ball of flames just in front of Endeavour. Endeavour is thrown back as he lands on the ground. Endeavour pulls himself up off the ground as Touya jumps onto him, grabbing onto his shoulder as he places his feet on Endeavour's chest. 

"Stop your flames, Touya!" Endeavour yells as he holds onto his son.

"Loook!" Touya yells as he sets fire to his hands. 

"I don't want... to let you die!" Endeavour says as he grits his teeth. 

"Natsu-kuun- let's playyy!" Touya yells as he looks around for Natsu. 

His consciousness... how was he able to keep going until now... with heat that's hot enough to burn even me? Touya... you are- 

Endeavour says as his skin slowly starts to burn. He puts his hand out to place it on Touya's chest when ice comes from his chest. 

Rei's... Quirk? It's all... my responsibility. I thought I needed to bear it all and live a life of atonement. But you were always watching me, weren't you? I couldn't watch you the way you wanted me to... I needed to make it up to you, too. I still have the same dream- the dream where my family is together without me. 

Endeavour says as he remembers the reoccurring dream he gets nearly every time he shuts his eyes. 

"I won't let you die alone" Endeavour says as he looks at Touya. 

Endeavour forms flames where his hand should be as he grabs Touya's waist, "but... I won't... get anyone else caught up in this either!" he says as he starts to fly himself and Touya into the air. 

I won't be able to get us far enough away from the ground. Touya, I'll borrow your firepower and get far away from the ground. Wait! Please wait! Just a little longer! 

Endeavour says as Touya flames become too hot to handle. Suddenly, there is a wisp of cold air as Endeavour turns around. 

"Rei?!" Endeavour says as he spots Rei on the ground, "don't! Why are you here?". 

"Touya!" Rei shouts as she tries to use her Quirk to cool Touya down. 

Are you trying to cool him down, Rei?

Endeavour asks as he realises what she's trying to do. 

"No! Get away!" Endeavour yells, worried for his wife's safety, "you'll just burn to death!". 

"The same goes for you and Touya, right?" Rei asks as she looks down. 

"Mommm!" Touya calls out to Rei. 

"Touya..." Rei says as she starts to cry, "I'm sorry!". 

"Natsu-kuun, Fuyumiii-chan!" Touya yells as he looks for his brother and sister. 

Rei gasps as she looks behind her, seeing Fuyumi and Natsu there, too, trying to use their Quirks to help as well. 

"You can't!" Rei shouts worriedly. 

"No! I don't want anyone to go away anymore!" Fuyumi says as she shakes her head, "Touya, don't take everyone with you!". 

"Don't cause anyone anymore trouble, stupid brother!" Natsu shouts as he looks at Touya. 

If I increase the heat by my movements, then Touya's body will... 

Endeavour says as he thinks about what he should do next. 

"Please, I'm begging you-" Endeavour says as he looks at his son, "let everyone else go!". 

Touya groans in pain as the flames continue to take over his body. 

Everyone's... watching... is that all it was? Something as simple as this? I wish I'd realised sooner... 

Touya says as his body starts to let off more flames which engulf those around him within them. 

--- where Shoto, Koko, and Tenya are ---

Koko holds onto Shoto as Shoto creates an airplane like structure around the three of them to help streamline Tenya's movements as the wind rips past them. 

"I can only take you this far!" Tenya says as his engines start to stall. 

"Thanks, Iida" Shoto says as he creates Phosphor over his chest again. 

Tenya falls to the ground as he throws Shoto, Koko going with him as Koko grabs Shoto underneath his arms as she flies the two of them towards where Touya is as she propels them with her air Quirk, too. 

"Todoroki-kun, Koko-kun!" Iida yells as he watches the two of them disappear, "thanks to you two, I'm becoming who I want to be! So the two of you should be who you want to be, too! And if that's a lover to one another, then so be! I'll be here, supporting both of you!". 

"Tenya, shh" Koko says as she blushes. 

"Koko, after this... if I don't hear you say I love you back... I might just cry" Shoto says as he looks up at her. 

"You idiot... of course she loves you. She just doesn't know how to express it. So just remember that. No matter what happens to Koko, she loves you" Koko says as she looks down at Shoto. 

"Sorry. I got so carried away that I thought you were the real Koko" Shoto says as he looks down, his face flushing red. 

"It's fine. Don't worry about it. Just remember to get the answer from her" Koko says with a giggle. 

"I will" Shoto says with a small smile. 

The two of them look ahead of them as they close in on the damage area. 

--- at Gunga ---

Endeavour holds onto Touya for dear life as Fuyumi, Rei, and Natsu work together to cool the two of them down, when they hear rapid footsteps from behind them. They all look over and see Shoto running towards them. Shoto yells as he jumps upwards, towards Touya. 

When you surpass various limits... things end up getting inverted... 

Shoto remembers Touya's words. 

My origin... if only it were so simple... if I'd been able to face them earlier... there are still things I want to argue about and say! 

Touya says as his voice breaks. Suddenly, Koko flies in as she pushes Endeavour away. Endeavour looks up at Koko as she wraps her whole body around Touya. All of them watch as yellow energy forms around them. 

"Sakura... what are you-" Touya manages to get out, "Koko, that hurts. Stop-". 

"Shh, I know, Touya. I know it hurts" Koko says as she starts to cry, the flames slowly stopping, "I know it hurts but bear with it. I don't want to lose you, Touya. There's so much you can still do. You need to reunite with Ten. You need to go home with your family. You need to eat all of your favourite foods with your brothers and sister! There's a lot you have to do, Touya. So let me save you! Let me be your hero!". 

"Great Glacial Aegir!" Shoto yells as he freezes the flames, the pressure exploding as it starts to snow, frost spreading everywhere. 

Touya goes limp in Koko's arms as she flies them to the ground as she lies Touya down. Natsu comes over as he sits next to his brother. 

"What did you do?" Natsu asks as he looks at Koko. 

"I took his Quirk. There's nothing I can do about the way he is, but let's hope the hospital can come up with some miracle, yeah?" Koko says as she looks at Natsu. 

Koko gets up as she looks at Endeavour who is conscious, but struggling to move. She looks over at Rei who is unconscious in Fuyumi's arms. 

"Koko, thank you" Fuyumi says as she starts to cry, "thank you for loving my brothers". 

Koko nods as she looks at Shoto. She runs to him as she helps his sit down on the ground. 

"You did it, Shoto. You did it" Koko says as she kisses him softly. 

"You were... all here?" Shoto asks as he looks around at his family who have burns now, "I see... it's not good, but I'm glad... I might not have been able to stop him with just Great Glacial Aegir... because Touya-nii raised his firepower higher than what he had during our first fight...". 

"Shoto" Fuyumi says as she looks at her little brother. 

"E-Everyone..." Touya manages to say, "die... scum Dad... die... all of you... me too... die...". 

He's freezing from the inside?

Natsu questions as he grips his brother's hand. 

"Wait, what should we do?" Natsu asks as he looks at Fuyumi, "it's going to be hell after this". 

"Touya..." Endeavour says as he crawls over to Touya, "sorry... sorry I didn't go to Sekoto Peak" he says as he puts his hand on Touya's chest. 

"I hate you... Dad" Touya says as he starts to cry, "the whole family... Sakura, you smiled at me... like you always would... when you left me... on my own. You're so... mean". 

"I know. I'm sorry, Touya" Koko says as she starts to cry. 

"Yeah, tell us" Endeavour says as he starts to cry, "more!" he says as he puts his head on Touya's chest, "Rei... sorry for driving you into a corner. Fuyumi... sorry for pushing everything onto you. Natsu... sorry for neglecting you. Shoto... I'm sorry for everything". 

Shoto looks down as he passes out in Koko's arms. Koko starts to cough up blood as she covers her mouth. 

"Koko?" Fuyumi says as she looks at Koko. 

"I'm sorry. But this is as far as I go" Koko says as blood spills from her eyes, "when you get out of here... ask for Eri. She might... be able to help Touya. She'd want to... since he's best friends with Tenko. As for me... can you tell Shoto... I'm sorry... and that... I love him, too". 

"You can tell him yourself" Natsu says as he looks at her, "where are you going?". 

"I'm sorry, everyone" Koko says as her head droops, her arms letting go of Shoto as she rests her head on top of Shoto's as she peacefully passes away. 

--- where Koko, Aizawa and Present Mic ---

Koko coughs up blood as she manages to force Kurogiri to let go of her.

"Koko!" Aizawa yells as he pulls her into him, Present Mic standing in front of them both, "are you okay?".

"Mm hmm" Koko says as she wipes the blood from her mouth, "but Dad, before we came here, I made some clones of myself and sent them to the different locations so they could help the others. The one at Gunga, she managed to take my Father's Quirk".

"The whole thing?" Aizawa asks as he looks at her.

"Yeah" Koko says as she struggles with her breathing, "I can feel it. It's overpowering. There's so many Quirks here. This is one hundred years of pure hatred and power. Dad, if Sakura wakes up-".

"She won't" Aizawa says as he holds Koko's face, "I won't let her take you away from me. I've got you".

"We've got you" Present Mic says as he puts his hand on her head, "we're not letting you go. You either, Shirakumo".

--- where the Todoroki family is ---

Endeavour continues to lie with Touya as Fuyumi, Natsu and Rei all sit around Shoto and Koko. Koko's body is freezing to the touch, and Shoto isn't waking up.

"I can't believe it" Natsu says as he looks at Koko's lifeless body.

"Why though?" Fuyumi asks as she starts to cry, "she was too young".

Shoto groans as he starts to wake up.

"Mum, why is everyone crying? Did Touya-nii-?" Shoto asks as lump forms in his throat.

"No, Shoto. It's not that" Rei says as she looks down at Koko's body.

Shoto follows his Mother's gaze as he looks down at Koko's body. Shoto can't speak, the words won't form. He gets up as he walks to her. He sits down as he brings her body to him. He wraps one arm around her waist, the other cupping the back of her head as he hugs her tightly. He starts to cry as he does his best to muffle the sound.

"Shoto, she said something to me... before she died" Fuyumi says as she rubs Shoto's back, "she told me to tell you that she loves you, too".

"That doesn't mean anything" Shoto says as he hugs Koko tighter, "she needs to say it to me with her own words, with her own voice".
