Chapter 1: Kaiyo and Izuku Midoriya: Origin

My name is Kaiyo Midoriya, Izuku Midoriya's older twin sister. That's right twin sister, and five minutes older than him. Though I'm guessing you're wondering what this story is going to be about. Well, it's going to be about my brother and I, along with our friends, on our journey to become heros! So, let's get to the story shall we? Cha!

"Izuku! Wait up!" I yelled after him as I ran to catch up. This was normal most days when heros were out and about or were near us fighting villains. Especially if the new ones were doing their debuts.

"Come on Kai-nee!" Izuku yelled back while jogging in place for a few minutes before taking off again.

I catched up to him and ran beside him till we came to a stop behind a huge crowd, and saw a big villain on the train tracks. "That's a huge villain!" Izuku exclaimed before going to the front, so, he could write in his hero notebook. "Maa, he never changes." I said softly with a small smile on lips, and my one hand resting its knuckles on my hip. I closed my eyes and gave a esaperated shake to my head before moving up next to him to watch. We ended up next to two guys. I glanced at Izuku, and a soft look came upon my face.

My eyes went back to the villain, and my soft look went away only to be replaced with a frown and my eyebrows scrunching. 'Why the train tracks?' I thought while thinking of why he would go up there when he could have escaped a different way. Everyone let out exclaims of shock as the villain knocked over the line for the train. As it came crashing to the ground a man ran out, and got underneath it stopping it from hitting the ground.

"It's Death Arms!" Someone behind us exclaimed, and I looked over at my little brother his eyes sparkling in excitement. Then water went out in front of the crowd as a way of blocking them from the fight. Then someone else shouted, "Backdraft!". I heard two of the guys near us talking about the villain. 'A purse snatcher? Really?' I thought with a sweat drop, and then flinched as I heard girls yell out Kamui. Okay, I admit he is cute but not my type.

"Kamui Wood! The young and talented rising star!" Izuku exclaimed making the man next to him ask if he was a fanboy. "Um, well. . ." I wasn't paying attention as I was trained on what was happening.

Then Izuku shouted out the attack Kamui was just about to do when suddenly a giant women comes crashing into the villain yelling, "Canyon Cannon!" After that everyone grew shocked of what just happened. When the women stood up and said, "Today is my debut! Pleased to meet you all! You can call me Mt. Lady!"

With that men started taking pictures saying "Here it is." Creeps. Then suddenly I looked at Izuku who started taking notes, and started his habit of mumbling. I walked up to him and peered over his shoulder as he wrote down Mt. Lady's quirk. The guy that was standing next to him exclaimed, "Oh, you're taking notes? Then you must be going as a hero, well good luck!" And gave Izuku a thumbs up.

"Yes! I'll do my best!" Izuku exclaimed back smiling brightly as a pink hue dusted his cheeks.

"Since you're all third years, it's time for you to think seriously about your future." The teacher in front of us said. "Then I'll pass out handouts for your future plans now, but...you're all… pretty much planning to go into the hero course, right?" He said changing from his tough demeanor as everyone let their quirks out after he said that.

Besides three people, my brother, myself and Katsuki Bakugou. The one thing about Katsuki is that he's too proud to do what the others are doing. But that doesn't mean he won't say something. And as for me because I didn't feel the need too.

"Teacher! Don't lump us all in the same group. I'm not gonna be stuck at the bottom with the rest of these rejects!" Katsuki said with a grin on his face.

Everyone exclaimed at him out of anger, "That was uncalled for, Katsuki!" or "Yeah, Yeah!", from people agreeing to the first thing that was said. Yet through all that the teacher goes and says, "Oh, if I remember correctly, you want to go to U.A. High, right, Bakugou?" Causing everyone to shut up. But with that it brought attention to my brother and I. I may not have a problem, but it's my brother I'm worried about. Because right after Katsuki's excalimtion the teacher also goes and says, "Oh, yeah, the Midoriya twins also applied for U.A. High." Oh goody here goes the volcano.

Everyone started laughing at my brother, yet, not me. I let out a sigh at everyone as I lean back and put my elbow on Izuku's desk since I'm right in front of him. Only to have the firecracker explode at his desk. AKA Katsuki.

"Hey, Deku! You're below the rejects! You're quirkless! How can you even stand in the same ring as me?" Katsuki said with murder on his face. Izuku tried to calm him down telling him to hold on, and that he didn't think he was better than him. After Katsuki set an explosion off next to Izuku's head that's when I got up. I walked behind Katsuki and did what no one else in our class can do. I grabbed his ear and pulled him away from Izuku.

"Ow! What the hell are you doing you old hag!" Katsuki yelled at me yet stopped as he saw my face. If there's one thing Katsuki fears, it's my anger.

"Idiot! Stop being a loudmouth and an ass, and sit the hell down quietly!" I yelled back twisting his ear causing him to wince and nod to what I said.

~~~~~ In another part of town ~~~~~

A sludge villain ran after a women screamed, and yelled back at the man who called him a thief to try to catch him.

All the bystanders were looking around wondering where the hero's where and that the sludge villain was taking advantage of the chaos that morning.

Then All Might, the number 1 hero, appeared and gave his famous catch phrase while going after the villain. "Have no fear! Why? Because I am here!" He exclaimed.

~~~~ Back at the school ~~~~

School just ended but I was l already outside waiting for Izuku. I took out my phone seeing that what happened this morning was already on the news. 'Maa, Ototo* is going to love this, and will want to take notes once we get home.' I thought as I stood near the koi pond smiling like an idiot. Till something hit the water of the koi pond. I jumped and looked at what it was only to see Izuku's notebook in the water singed around the outside on the edges. "Katsuki. . ." I muttered while picking it up out of the water. Then I heard footsteps behind me.

"Kai-nee. . ." I heard my little brother say softly behind me as I turned to look back at him I saw his eyes trained on his notebook. I frowned as I went and pulled him into my arms. I heard him mumble "Stupid bastard" and knew who he was talking about.

~~~~~Flashback~~~~~~

"Mom! Mom!" Two kids, boy and girl, yelled for their mom as they appear outside a door. The boy holding an All Might figure in his one hand while holding his sister's hand with his free hand. "Mom, the computer?!" They asked with excitement in their voices. Their mother looked down at them and smiled and said "Again?" While going to the computer for her two kids to watch,

"Maa, Izuku and Kaiyo, you both probably added ten thousand more views to the video just by watching it. Also, it's to scary for me to watch." She said as she looked at her kids who were looking excitedly at the computer screen.

"Can you see that? He's already saved a hundred people!" The man in front of the camera said. The person standing behind exclaimed, "That's crazy! It hasn't even been ten minutes!"

"He's laughing!" Someone yelled as Izuku and Kaiyo watched with pure adoration for the man laughing.

"It's fine now. Why? Because I am here!" The man exclaimed. That man being the number one hero All Might.

"He's so cool!" The kids both exclaimed, with Izuku saying "Once I get my Quirk, I wanna be like him, too!"

Only to have his dreams all crashing down. While Kaiyo was born with multiple quirks, Izuku was born quirkless. Kaiyo sat there feeling numb along with her brother.

Back at home Izuku sat in the dark watching the video over and over again. When Izuku asked if he could be a hero too both their mother and Kaiyo broke down crying, hugging him.

~~~~~End Flashback~~~~~

I was walking next to Izuku as we walked home. I glanced over at him seeing a determination look on his face. I smiled softly at him. "Maa Izuku I know you will make a great hero." I said to him only to have him look at me in shock. "And I'll be right behind you." I add with a smirk with a thumbs up to him. He smiled and then walked forward and started to laugh. I followed behind with a sweat drop going down my head. 'That's a creepy way to respond to something like that. . .' I thought yet my eyes narrowed as I heard something behind us. I turned as well did Izuku when we heard a disoriented voice say, "A medium-sized invisibility cloak. . ."

"Villain. . . " Izuku said shaking.

"Ototo!" I yelled shoving him out of the way and getting trapped by the sludge villain.

I started to lose consciousness as Izuku yelled out my name, and the villain saying something. And then I blacked out.

When I regained consciousness Izuku was leaning over my smiling in relief and All Might standing behind him. Wait. . . ALL MIGHT!? I sat up startled and looked back and forth between Izuku and All Might. "What. . ." Was all I was able to get out.

'Maybe I'm still unconscious and dreaming at the same time. . .' I thought and then I opened my mouth again. "Nee, Ototo am I still unconscious or am I awake?" I ask with my one eye twitching.

"You're conscious." Was all Izuku said before I got up and bowed to All Might.

"Thank you All Might! For saving my brother and I!" I exclaimed and I added in my thoughts, 'And everyone else.' I looked up when I heard a booming laughter and saw All Might wave away my thank you. "No need young girl," All Might said as he smiled at us. "You two being safe is all that matters."

I smiled at him and felt my brother come stand next to me. "Um, All Might, I have some questions for you." My brother started but All Might also started getting ready to leave but before he jumped Izuku attached to his leg. I blinked and looked be side my only to find he really was gone.

"I-Izuku!" I yelled while looking up at the sky. 'Shit the only way to keep up with them is. . .-'"Pegasus celestial soul bond!" I yelled out the rest of my thoughts as a bright white light engulfed me before I shot up into the air. The light went away showing that my clothes changed to a white dress shirt, black slacks and black dress shoes. And on my back two big white wings sprout from my back. The wings opened and gave a big flap that launched me into the sky.

I looked around and saw a them a few miles away to my left. With that I started going in that direction. 'Next time I'm making sure he doesn't take off without me.' I thought as a flew behind them. I saw the dot that was All Might go and land on top of a building. I was still behind them in the matter of distance. It took me awhile to get there and once I did I circled than landed on the building that they were on. Once my feet touched the ground I undid the transformation, so, I was back in my school uniform. When I looked up confusion ran through me. First, my little brother looks like his dreams got smashed to pieces, and also a really sickly man who looked to be on his deathbed.

"What. . ." I asked my voice barely making a sound as I stared at them.

"Kai - nee. . ." Was all Izuku said to me while looking to me and my temper flared, and I turned and glared at the man sitting in front of the railing.

"Who are you, and what did you to my brother?!" I asked with rage twisting into my tone. My glaring eyes boring right into the man. Sweat started to run down the man's forehead.

As I started going towards him I felt a tug on my sleeve, and as I turned my head my eyes widen in shock seeing my little brother looking like his soul was taking. "Kai - nee. . . don't. . ." His voice whispered out. But my anger returned twice as big.

"What did you do to my brother. . ." I said as I turned back to the man. "What did you say. . ."

"I told him the truth -" He started but I cut him off. "WHAT DID YOU SAY!" I yelled looking at him, and I felt Izuku's grip tighten on my sleeve.

"I told him that he couldn't be a hero without a quirk." The man said seriousness going into his tone and body language. And that's when I went off on him.

"I don't care who you are, but never tell my brother that!" I started at him. "Yes, I know being a hero is dangerous and it's risky, but that doesn't mean he can't be a hero! A hero is someone who puts the well being of others above their own safety. A hero gives his life for people! And my little brother is a hero with or without a quirk!" I yelled as tears started coming out of my eyes.

"Kai-nee please. . . Stop yelling at All Might." Izuku said making me freeze.

'All Might told him that he couldn't be a hero? No wonder ototo is about to break down.' I thought as I turned to hug him. His hands came up and gripped the back of my uniform as his head was buried into my shoulder.

"I am sorry." All Might said as he got up and headed to the door. He turned and looked at us and met my eyes glaring at him. He lowered his eyes then walked through the door leaving my brother and I standing alone on the roof.

~~~~~ Line Cut to Next Scene ~~~~

'What All Might said to him really crushed him.' I thought as I glanced over at Izuku. We were walking down the road going towards home when across the street a explosion happened. We both stopped and saw a big crowd had gathered at the entrance of a backway. We both glanced at each other and jogged over and tried to look over people's shoulders.

Finally we got through to the front where we saw the sludge monster that All Might captured. I heard a gasp from my side, and I looked over at Izuku who had his hand covered over his mouth. Then I heard people around us talking about what's going on. "The hero's aren't doing anything," and "The villian has had the student for 35 minutes already."

My eyes widened because whoever the student was wasn't going to make it for very long. And then people were yelling, and my eyes widened again this time in fear as Izuku ran towards the sludge villain, and I saw who the student was.

And that's when I was running after Izuku. "Aquarius celestial soul bond!" I yelled as light came over my again. This time my uniform transformed into a bikini top with a dark blue silk skirt, and sandals on my feet. I held out my hands to the side and a amphora appeared in my hands. "Izuku! Grab onto Katsuki!" I yelled after he got to him and I threw my arms in front of me before yelling, "Water Tornado!" And water shot out toward them, and the water pushed the sludge villain off of Katsuki so that Izuku could pull him away, and they fell back onto the road. I reached them and stood in front of them until a blur appeared in front of me turning into All Might.

"I wasn't doing what I said to you, young midoriya boy." All Might said, and stood in front of use and yelled, "Detroit Smash!" And blew the sludge villain away and the wind current pushed all the way up to the sky and caused it to rain a little bit. I undid the transformation before turning to see my brother and Katsuki knocked out a little. I smiled before crouching in between them.

"My two stubborn and idiotic boys." I said softly as they started to wake up.

As the press bombarded All might the other hero's were over towards us praising Katsuki and I while belittling Izuku. Which caused me to glare at them, grab my brothers hand and walk away.

~~~~ Line Cut to Next Scene ~~~~

Izuku and I were walking down the road that headed to the apartment complex we lived in when we heard someone coming up behind us. We both stopped and looked behind us to see Katsuki stop a little away from us. Looking pissed off as usual.

"Just so you both know I didn't need your help! And you deku don't do something so stupid again or I'll kill you!" He yelled before turning and speed walked away.

Izuku and I looked at each other with an eyebrow raised before we both laughed softly with small smiles on our faces. "That's Kacchan for ya. Huh, Kai-nee?" Izuku said to me to which I nodded at his words. As we turned to start walking back All Might came out of an alleyway right in front of us. Making both of us gasp and jump back.

"All Might!" We both exclaimed. "How did you get away from the press?" Izuku added as we both stared at him.

He let out a booming laughter before answering. "HAHA young midoriya's a hero can always-" He stopped talking when blood came from his mouth and he went to his deathbed looking state. Causing both Izuku and I to let out yelps in shock.

"As I was saying hero's need to know how to get away from the press." He said as he wiped the blood from his mouth. "Yet I have come here with a proposition, a correction and a solution, young midoriya boy." All Might said looking at my brother.

I looked at them and smiled softly before walking pass All Might. "Take good care of him All Might." I said while walking by him .

The reason why I didn't stay that day is because I knew this was my brothers chance at being a hero. So, like any sister I will stand beside him with whatever he choose to do. And I also knew that this was the start of our journey.

Finally I am done! So, how do you guys like it so far? Also Sorry about the dialogue but I'm trying out a new way of writing that I may or may not stick with for later chapters! Also we're just getting fired up!
