Battle Training(2)

Deku prepares his Nomu for his rematch but while doing so he felt a hand placed on his shoulder. He turns around to see Toshinori behind him. "What do you want, Toshinori?" "These augmentations you've done to yourself. I can tell you've grown significantly more powerful. I want you to give me these augmentations aswell. Make me stronger, Deku." he replies with strong determination in his eyes which locks in with Deku's. He pauses his work for a moment and turns around. "If you're willing to die for it then it can be achieved." after saying that Toshinori laughs hysterically. "You shouldn't fear my death. As long as my heart is intact, I can't die." He confidently replies and Deku finally takes the time to examine Toshinori's body. "Let's test that hypothesis." Deku says before appearing next to Toshinori, which startles him as he couldn't believe the incredible speed he now has.

In the next moment, he feels a sharp pain in his arm and as he looks down, he sees his right arm was gone. He grunts in pain before quickly regenerating his arm which impresses Deku who suddenly appears in front of him holding Toshinori's severed arm. "How did you do this to yourself?" Deku asks with a penetrating gaze. "I didn't, The man who is the key to retrieving All For One is the person who did this to me. He is also from another world and the people in his world are insanely powerful, no man in our world can take them." Toshinori replies which intrigue Deku. "You are pathetically weak right now so what makes you think someone from our world can't take them down?" "You best avoid any arrogance, Deku. I fought one of them, a boy with a cloning skill. I used all the strength I had and I couldn't defeat him. Then I learned that his power is divided among the clones and he had made 4 while making me battle one to make it easier for me. After he gave me a leg up on him and gave me a significantly weaker version of himself, I stood no chance. I doubt even you can win against one of them in your current state." Deku pauses and thinks for a moment before looking back at Toshinori. "What's his name?" "His name is Meliodas." Deku pauses again, thinking about something before smiling. "Very well, I'll help strengthen you." Deku says before disappearing and reappearing next to his computer. He places down the severed arm and began typing something. "The augmentations will take some time to perfect for a new body so until it's finished you'll be trapped inside for a while. Is that alright?" Deku asks with a sinister grin and Toshinori nods. "I have no objections." Deku walks to the cylinder he was in. "Take off your clothing and step inside." he says and Toshinori follows his orders, ripping off his clothing and stepping into the chamber and it closes immediately after.

"I can't wait to see what happens." Deku says as gas fills the chamber, making Toshinori slowly fall unconscious. "Good luck, One For All." Deku says and Toshinori falls unconscious. He hands one of the Nomu the severed arm. "Analyze the composition and blood of his arm. It may prove vital in understanding what he did to give himself such impressive regenerative abilities. I want to take it for myself." he says as he turns to the computer. "I best prepare my last body, in case this bastard decides to betray me or I die in combat." Deku says as he types something in the pc but then stops in shock. "Wait...i-its possible?!" Deku's shock quickly shifts to a maniacal smile as he begins to laughs. "This is becoming very, very interesting."

They all rest while waiting for Horiko and Eri to regain consciousness and with anticipation, they never noticed a half hour flew by as quickly as a gust of wind fades. Soon after, Eri woke up looking somewhat confused and tired. She examines her surroundings and see's Christopher walking towards her and he reaches his hand out to help her stand. She reciprocates and he pulls her to her feet but didn't let go of her hand. She was confused when his hand began to surround itself with strange blue dust which engulfed her hand. She's more confused about this blue dust but her feelings soon shift to surprise when she felt a sudden jolt of energy that spread throughout her body and when Christopher pulled back his hand, she felt refreshed. As if waking up from a goodnight's rest.

She stares at Christopher with a confused looked to which he responds by smiling. "Had a good sleep?" he asks to which she smiles and jokingly responds "Worst one so far after following those morons." pointing to Ray, Kuroshi, and the others and Christopher laughs. "Perfect, looks like you're ready for your next fight." Christopher turns to Kuro and smiles. "Are you ready, boy?" Christopher asks to which Kuro pauses for a moment. "She's strong, Much stronger than I thought. I can't waste any time if I want to take her down." He straightens himself and his expression shifted to a more serious look. "Yes, I'm ready!"

They both walk into the field which Christopher rebuilt while Eri and Horiko was unconscious. They stare at one another and Eri notices the serious look on Kuro. "Looks like he won't go easy on me. The stories I was told from One For All showed him as a very dangerous individual. I might have to go 50% right away in order to take him down."

"Are you ready?" Christopher announces.

" 3,

2,

1,

Begin!"

* * *

As his voice echoes throughout the field, Kuro wastes no time by using his darkness and causing large spikes to form beneath Eri's feet but she dodges quickly and disappeared in an instant. Kuro focuses on his surroundings and hears a footstep behind him and right before Eri's attack lands, A spike appeared from the ground and stabs her in the arm before Kuro swiftly turns around and kicks her to the wall. "She can heal all her injuries. if I want to win, I'll have to fight her like I want to kill her." Kuro monologues as her wounds heal and she stands up before looking at Kuro, surprised by the counterattack. "Seems like he can catch up to me at 50% I have to finish this quickly." she thinks to herself before walking towards Kuro. She dashes at Kuro again, clenching her fist as she tries to land another attack but Kuro manages to create a dark wall and jumped back, blocking her attack and he uses a dark spike to penetrate her shoulder. Kuro breathes a silent sigh of relief as she stands back up. "I need to find a way to debilitate or immobilize her if I can't defeat her." Kuro says as he thinks of possible options available for him to use before noticing her shoulder healing itself and he remembers her falling unconscious from what Christopher claimed was an overuse of her quirk. "I need her to use her power." he thinks to himself as he takes a step forward when Eri suddenly disappeared but he prepared by surrounding himself in darkness which proved successful after Eri's attack was blocked by the darkness and she jumped back, returning to Kuro's vision. "I couldn't see or sense her this time. It seems she's faster now." Kuro monologues to himself as the darkness surrounding him dissipates. "I need her to keep using her quirk" he adds before dashing towards her. This catches her off guard but she quickly tries to attack by firing air bullets in his direction but Kuro dodges them. She jumps into the air but the moment she did, the entire place was covered in light and dark spikes, extending towards her and stabbing her throughout her body continuously. She keeps rewinding herself to heal her injuries and fires a full punch at 100% which sends a shockwave that destroys the spikes that stabbed her and throughout the field.

She gets up, breathing heavily as her injuries slowly heal. She stares at Kuro with a menacing gaze as she spits out the blood in her mouth. "That's it." she whispers before she suddenly disappears. Kuro, sensing the imminent danger, closes his eyes and focuses intensely. As Eri's attack touches Kuro's face, to her surprise she felt nothing and her hand began to phase through his face and she passes through him and lands in front of him, creating a large crater where she landed. She quickly turns around but to her surprise, he was gone. She quickly scans the entire field, looking for Kuro but found no trace of him anywhere. It's eerily quiet, she stands in place trying to predict Kuro's next action. While investigating her surroundings, she and Lemillion lock gaze for a moment and she remembers back to her battle against him previously, she quickly realizes that Kuro used his power and will strike from below to which she activates One For All, and immediately after doing so Kuro reappears from the ground but fell into Eri's trap. She extends her fist to meet with his face and he blocks with his arms but Eri's fist slams him into the ground forming another large crater.

Kuro turns into light and disappears before reappearing behind Eri, placing her in a chokehold and trying to suffocate her but she quickly activates One For All at 100% and snaps her fingers, causing a massive shockwave that destroys the building again and blows Kuro back. She gets back up again and rewinds her broken fingers before shaking her hand repeatedly and turning to Kuro who also stands up.

* * *

Everyone stares at the battle in awe as the fight was truly shocking. Both kids had impressive strength and skill with their quirks, rivaling that of pro heroes but while everyone focuses on the fight at hand, Christopher's mind is elsewhere as he was sharing his vision with a clone of his in Kuro's world, watching Toshinori and Deku's actions. He returns back to the current world and his focus returns to the fight as both Eri and Kuro are tired from the fight but Kuro quickly dashes at Eri and this scene reminds Christopher of Kuro's fight with Lemillion and the white lightning that surrounded his body in during his final attack. "I don't think he knows how to activate it." Christopher monologues as he watches the fight unfold and strokes his beard. "For the time being, I won't help him unearth that power, I'll let him try to find it himself. If he doesn't then he stands no chance of winning."

Eri quickly fires air bullets at Kuro which he dodges and dashes towards Eri, she quickly activates One For All at 100%, bringing her fist closer towards Kuro's face but it phased through it and his body phased through her before he turns around with a kick which knocks her across the field. She gets back up when she's suddenly stabbed in the back by a dark spike. She coughs up blood and tries removing it but then a barrage of spikes followed and stabbed her throughout her body, preventing her from moving. She tries moving her fingers together to snap but when it moved, all her fingers were stabbed along with her toes. She screams in agony as she tries desperately to escape. Kuro finally uses this opportunity, pointing a large spike in her face. "It's over." he says

Christopher stares at the fight for a moment before closing his eyes, his vision shifts to a beautiful forest where he hears the humming of a child behind the trees. He walks towards the source and sees Aika once again playing with her rabbits and she turns around to see the old man before her expression shifts to a more upset look.

"I was hoping for a better reaction, Aika."

"What do you want, old man?"

"Nothing much, just here to enjoy the beauty of this place."

"I highly doubt it, you aren't the type to look for me for no reason."

Christopher laughs slightly before he walks towards her and sits down on a rock next to her. "I suppose I'll get straight to the point. It's about the future of All For One."

* * *

"What about it?" Aika asks, confused by his statement.

"To cut to the chase, Kuro needs power. Power which he doesn't have enough of right now. I need to make sure he can handle himself in his future fights because he can't be protected by me, Meliodas or Ban. I want you to allow him better access to your arsenal of quirks."

"What makes you think he can handle them?"

"You may not believe me but I've seen an alternate timeline where he gains access to your abilities far sooner than now. You may not see it but he is ready, more so than ever to begin training with the other quirks in All For One."

Aika pauses for a moment, staring at the ground as she ponders about what Christopher said. After a moment she smiles and raises her head, locking eyes with the old man who smiles in response. "I think you're full of shit, old man."

Hearing this he falls off the rock from her unexpected response before getting up. "You sly fox, I thought you would agree when you smiled." Christopher responds and Aika's smile grew before turning her gaze back to the rabbits. "Even though you're strange and may or may not have special abilities, no one in the world has a quirk that can see other timelines, and even if it were true, I doubt that inexperienced brat can handle my quirks when he struggles so easily with 'that bastard's' quirks."

"I can show you the timeline if you wish or I could reveal what your original quirk was as further evidence."

"I don't care, he can't handle it. If you have nothing else to do here then leave." Aika demands changing her tone slightly. Christopher sighs before staring her down with a slightly annoyed expression. "I can see why your brother called you stubborn." he says before turning around but he was then stopped by Aika who grabs his shirt. "What did you say?" Aika asks, surprised by his statement. Christopher pulls his shirt away before turning around, facing the little girl.

* * *

"I suppose you aren't aware of this but your brother is alive. I have a clone currently keeping an eye on him." he replies which makes Aika take a step back. "B-But he's dead. I saw it with my own eyes, How did he survive?!" Aika says and Christopher sighs again. "He has a machine which held onto multiple clones of himself. After he died, I'd assume his clone took his place again. I investigated his lab and it appears he only has one clone left."

Aika was silent for a while, staring at the ground. Christopher stares at the child before closing his eyes and turning around. "Fine, I'll help him." her voice cracks and stutters as Christopher looks at her, her head still facing the ground. He walks over to her before patting her on the head. "I'll take you up on that offer soon but not yet." he says but Aika doesn't question it, staying silent regardless and Christopher nods his head before turning around and disappearing. Aika turns around before biting her thumb. "How did you end up like this, Izuku?"

* * *

In an open field in the distance, there lies a little girl in the grass. The wind blew mildly while the birds sang beautifully. The girl rests calmly, embracing the comfort of her surroundings before being awoken by a voice in the distance. "Aika, dad's looking for you!" the voice calls out to her and she sits up before turning in the direction of the voice. A young boy rushes towards her, his messy green hair flowing through the wind, his emerald green eyes, his pale skin, all noticeable from the distance. The boy reaches to her before grabbing her arm and pulling her away.

"We need to hurry up!"

"What's the rush?" she asks while giggling slightly.

"He says it's something important."

"If it's important, that old man can find me himself." she replies and the two of them stop for a moment.

"It- It isn't just that. Whenever dad calls for you, I can never get the chance to ask you to play with me so I came to ask you before you were taken by dad again." the boy says and Aika smiles before patting the boy's head.

"Ok, I'll play with you as soon as I'm finished."

"Do you promise?"

Aika raises her hand in front of him and curls it into a fist before raising her pinky finger.

"Pinky promise."

The boy smiles before doing the same thing and their pinky fingers wrap together before Aika gets up and grabs his hand and starts running. "Let's hurry!"

The boy smiles before getting loose from her grip and running ahead of her.

"Last one home is a rotten egg!"

the boy yells before the girl smiles. "You sneaky little-" she says before trying to catch the boy and they both laugh together joyfully.

* * *

Aika sits on the rock silently reminiscing her past. Tears fall from her eyes which she quickly tries to wipe away. A rabbit lays its paw on her knee as it tries to get on her lap but she turns in the opposite direction and curls into a ball, submerging her head in her arms. The forest's beautiful sunny glow begins to fade as a fog begins to set in and clouds cover the sun's rays. The rabbits all scatter away and disappear into the forest but Aika doesn't go looking for them. She doesn't move, leaving her head buried in her arms when she suddenly hears a voice in the forest, raising her head, it sounded like a little girl's voice.

She stands up, following in the direction of the sound, pushing through the dense fog before reaching a clearing she never knew existed. The sky darkens and she looks around when the surroundings suddenly shift, it glowed brightly with an orange pigment and when her eyes adjusted she realized it was fire and she was standing in the middle of a city as the fire burned through the building around her. Her expression shifts to one of fear as she recognizes this place, she then hears the voice louder, coming from behind her. She quickly turns around and to her horror she sees herself and a boy, breathing heavily and covered in blood. The boy with blood covering one half of his face stares at her before multiple clones suddenly appear around him and they all rush at the girl. She takes in a deep breath before pulling out her metal claws and savagely destroys each one of the clones before knocking the boy to the ground. "Why are you doing this?!" the girl cries but the boy doesn't respond, instead knocking her off balance and pushing her away. "I-I don't have a choice, Dad said you abandoned us after you were taken in by the heroes!" the boy cries before dashing at the girl with incredible speed and knocking her to the ground. "You said we would be together through anything, but you lied to me!" the boy cries as tears fill his eyes. Aika covers her mouth as she remembers all of this. She tries to rush over to them but to her surprise, her quirks wouldn't work but she rushes towards them regardless. "You don't know what I had to go through, what dad made me do after you were captured!" the boy cries before pulling out a knife. "I have to kill you, that's what dad ordered me to do!" the boy yells before plunging the knife down but stopped right above her chest. The knife shakes as he struggles to force the knife any lower. Tears begin to fall from his eyes as the boy shakes and doesn't stop, like the knife landed on a brick wall he was unable to push the knife any lower. "I-I don't want to kill you." the boy's tears begin to fall on her face. "Why...why did the heroes take you but left me to die in the rubble. I wanted to be with you even then, why did they take you away from me. Why did they leave me with that man to suffer? I didn't want to hurt anyone."

Aika reaches out and tries to grab the boy's shoulder but her hand phased right through him which startles her and suddenly out of the corner of her eye, she sees a darkened street covered in rubble from destroyed buildings, she sees an injured muscular woman with a white cape, dark long hair and blood stained yellow gloves limping towards the rubble as other heroes began to follow behind her. She sees the body of All For One on the side as the heroes begin lifting the rubble off the ground and found a little girl unconscious in the rubble which they help out, carrying the little girl on their shoulders before walking away. The girl soon wakes up and begins wrestling with the hero trying to escape his grip which she manages to do before running towards the rubble again, lifting some off the ground. "Izuku!" she cries out repeatedly as the heroes stand behind her, hiding their guilt before walking towards her and pulling her away. "Wait, my brother's still in there! Please, help him!" the girl begs

"If you can't kill her then let me help you." a deep voice says. Aika quickly turns back to the boy and one-half of his face is crying while the right smiles maniacally. "W-What's going on?" the boy says scared by the situation. "Don't worry boy, I'm simply doing my part as a father to give my children the nudge they need to get something done." the voice says before placing his right hand on the knife and starts pressing down but is pushed back by the boy's left hand. "Father please, don't do this!" the boy begs but he keeps pushing down on the knife as it starts to penetrate the girl's skin slightly. The boy quickly turns the knife on his hand and cuts it off, screaming in agony from the pain he caused himself. "I don't want to kill her!" the boy begs as he begins to stand up. "Very well then, I'll do it myself." the voice says and the boy's right arm begins to slowly grow in size and it slowly spreads throughout his body. "I knew you wouldn't be able to finish the job so I gave a self-destruction quirk to you. With this, you can destroy her and the remaining heroes aswell. You will have fulfilled your purpose." The boy begins to cry as he fears what will happen to him. He turns to his sister and both of them lock gazes. "I'm sorry, I'm so sorry." Izuku says and deactivates his quirk, returning some of Aika's quirks to her. Aika stares in horror as Izuku slowly walks towards her, each step he starts growing larger and larger. "Please, kill me." Izuku says and Aika was frozen. Izuku hugs the girl who begins sobbing relentlessly. "I can't!" the girl cries out. "I'm sorry." Izuku says before a black spike extends from his hands and stabs her, causing metal claws to burst from her back and he released her but the claws couldn't be controlled, moving in all directions before one of them went at Izuku and Aika screams trying to stop it from happening but the claw stabs Izuku in the heart and he falls to the ground. The lumps and growths throughout his body begin to shrink and Izuku lays on the ground as both the girl and Aika hold his head. The girl tried desperately to stop the bleeding but it was too late. The boy places his hand on her face before turning to Aika which startles her. "I see two of you. Maybe I can play with you both one last time. Maybe a game of hide and seek...or tag...or..." the boy smiles before his hand falls to the ground as he stops responding. The girl cries as she tries to save him but it was of no use. He had passed.

The scene disappears as Aika sits in place in an empty void before tears fall from her eyes and she wails hysterically. Christopher stands distantly behind her as he stares silently at what happened. He walks towards the devastated little girl, putting his hand on her shoulder and getting down on his knees. She raises her head and her tear-filled eyes lock with his own. His eyes express a sense of regret and sadness, "I'm sorry, I'm so sorry." Christopher says and she goes in for a hug which he reciprocates and they embrace each other warmth and creating a dim light in the cold, dark void.

Eri uses her tongue and slams it on the bottom of her mouth, creating a shockwave that destroys the spikes. She quickly rewinds her injuries before getting back up. "Let's finish this." she says before activating One For All at 100% again. Kuro prepares for her attack and she dashes in close and tries to land a punch, Kuro tries to dodge but her fist is too fast. Eri begins to smile when to her surprise, Kuro throws dirt in her eye before disappearing and reappearing behind her, knocking her to the ground. Kuro then kicked her in the air before trapping her in a box that stabbed her throughout her body. She screams in pain again and Kuro falls to the ground, exhausted before Eri breaks out again and falls to the ground, rewinding her injuries before getting up. "Dammit, how long is she going to stay conscious." Kuro monologues before getting back up again aswell. "I'll finish her in one final attack." Kuro says. He dashes at her again before creating wings behind his back and flies into the air. Eri fires air bullets to shoot him down but he's too fast and dodges them all.

Kuro flies towards her, preparing a light spike when she fires off an air bullet at 100% which destroyed the spike before running at Kuro at 100%, She tries to land a kick but Kuro ducks and dodges her kick. She turns to him and tries to land a punch but her fist was blocked by a dark wall. She maneuvers around the wall but to her surprise, he was gone. Suddenly he appears from the ground and punches her back and she counters with a kick which sends him flying into the air. She quickly jumps towards him when she notices in the corner of her eye a small white spark that passed her and Kuro appears behind her, surrounded by white lightning. He curls his hand into a fist and plunges it into her back which penetrates it and blasts her to the ground causing a massive crater to form around where she landed. She rewinds her injuries before standing up but was immediately sent flying into the air by another punch that penetrates her stomach. She quickly rewinds again but when she felt a force on her chest, sending her flying through the wall and into the city. She can't even see the attack's land. She coughs up blood as she tries rewinding her wounds again but yet again she's thrown back at UA again by another attack she couldn't see. Her back slams on a wall before she falls to the ground, trying desperately to regenerate and stand but then Kuro appears in front of her, finally allowing her a good look at him. Surrounded in white lightning, his hair stands like spikes and his left eye is pure white while his right eye is pure black. She stares in awe of the sheer power she sees. Kuro disappears and in an instant, Eri was filled with holes throughout her body and her torso was split in two. The injuries were too much to recover from and she falls unconscious from the attacks.

Kuro pauses while breathing heavily, the mysterious power seemingly deactivating and a large wave of pain kicked into Kuro who falls on his knees from it. Everyone stares in awe and amazement at what they witnessed before Christopher stepped forward and said nothing, walking to the two of them before releasing a green mist that began to heal their wounds. He turned to Kuro before smiling and turned back to the adults. "It seems obvious who won so I won't announce it but I have something to tell you all." Christopher states which confuses everyone. "What is it?" Kuroshi asks. "Pack your things, it's time to go back to your world. We have a war to stop."

Hey, thanks for making it this far. I guess you guys are sick of hearing it but yes, things came up that prevented me from working on this chapter for a while. I'm really sorry about it but there's nothing I could do, exams is a bitch but at least I'm happy to say I passed. I will try to update more frequently soon, perhaps even by tomorrow so you all will have to wait and see. Thanks for sticking by the story as it's progressed over time.
