The Promise to Protect His Family

"Oh yeah!" Maria realized what she wanted to ask her new big brother something.

"How did you like your gift? Did you get my move-in present?" Maria asked.

"Move-present? I think I got something, but could you please tell me what that is?" Izuku asked politely.

"(This boy is so polite and timid a little, it's so cute. It's a shame that we may have to use him for our own purpose.)" Maria thought giggled.

"Me and My Real Stepsisters: Youth in an Unmarked Lot." Maria mentioned the title and that soon clicks very hard in Izuku's head.

"What?! The game box… That was you! But why would you even buy a game like that?" Izuku asked with his face flustering all red.

"I thought you could use it as a guide from now on." Maria answered.

"Guide for what? Becoming a pervert which I hate!" Izuku yelled a bit in shock.

"Oh, come now. Is there anything you want a stepsister to make her to your liking in that head of yours?" Maria giggled and swayed her hips.

"(Unholy Crap! This girl is insane with lust, mostly the opposite of Mio!)" Izuku thought shocked, comparing his two new sisters to each other. Wondering if Maria does this to Mio too in the past.

"Not exciting enough? Oh, you probably think the game is boring, so why not do it with me in real life?" Maria offered as she lifts up the apron just a little to show off her legs.

"No! No! No! No! Please, don't do that?!" Izuku yelled a little loudly while waving his arms side to side in front of his face.

"The fuck is with all the yelling about? It's still so early in the morning?" Sapphire asked, coming in with a yawn followed by Raphaeline and Mio.

"Oh, well, you see, Izuku is about to take me however he wants for the first time." Maria lied as an embarrassing tease to Izuku.

"I promise it is NOT like that!" Izuku stated.

"It looks like Izuku has now found out about Maria being the embarrassing pervert little sister, I wonder how his little heart will take it." Raphaealine giggled, seeing this being a little funny.

"It's not funny at all, Mother!" Izuku screamed with his face going steaming red.

"If you even think about giving in to Maria's silly pervert antics than I'm going to give you a scolding of a lifetime you will never forget!" Mio warned with a scary glare. She knows that Izuku isn't a total pervert thanks to the good words from his moms, but she'll still have her guard up around him.

"Now, now, let's have ourselves some breakfast and we take our family photo together!" Raphaeline suggested with a kind smile.

"Wonderful idea, I just about to finished making breakfast! I hope you're hungry because my cooking is up notch!" Maria winked at Izuku.

"(Oh boy, this girl is going to make me feel crazy…)" Izuku thought sighed.

Everyone ate their breakfast together without any more issues with Maria trying to be all perverted to her new stepbrother, everything went well and the whole family steps outside to have their new and first family photo taken.

"Izuku, try to calm yourself down. You look stiff as a tree." Raphaeline advised while holding the camera.

"Right!" Izuku flinched a bit.

"Come on, son, you're acting like it's the end of the world. Our family is expanding and we're going to make this work however we can." Sapphire stated with a light pat on his back.

"Right." Izuku nodded then puts on a smile.

"That's a cute smile, you got there." Mio complimented, seeing Izuku smile like that.

"You really think so?" Izuku asked, a little surprised that Mio is being a little nice to him now.

"Yeah, you should try wearing that more often. Maybe people would take you seriously from now on." Mio stated.

"(Bold and honest, more than me in a way. Maybe having sisters won't be so bad, it could be fun.)" Izuku thought smiled and face the camera.

"Okay, I'm setting the timer." Raphaeline pressed the button and hurried over to the family.

"(Dad, big brother. I hope you two are watching over us from Heaven, me and moms are doing okay.)" Izuku thought hoped his dead father and big brother knows that the family doing okay.

And then, the picture was taken of the entire family now coming together.

(Later)

Izuku and Mio were sent off to do some grocery shopping upon the request of Raphaeline thinking they might need a little bit more food since they have two new mouths to feed, and to give them a chance to spend time together.

"Okay, we got everything we need." Izuku said, looking over the bags to make sure they got everything from the list.

"I believe so, Mother Raphaeline sure has a lot on the list to make sure we don't go hungry." Mio commented.

"Yeah, she cares a lot to make sure that we have everything we need to get through while also making sure not to spend too much money." Izuku explained.

"I'm gonna go get the bike. You wait here until I get back." Izuku ordered before running off to get the bike.

Mio let out a sigh and looks up at the blue sky, thinking about how her life is like now that she has a little brother and two mothers in her life now which is still quite surprising to her, but it's also warming and joyfully though she looks a bit sad for a second.

"Hey, baby. Are you all alone?" One guy with a baggy red hat asked grinning, he and few of his pals walking up to Mio.

"Wanna go have some fun with us?" One dirty blonde guy asked.

The five punks gang up on Mio seeing how she is so cute and sexy at the same time; one grabs her by the shoulder to "convince" her to come with him but Mio wasn't having any of that.

"Don't touch me. Do that again and I'll kill you a hundred times over." Mio threatened as she smacks the hand away.

"You're gonna kill us?" One dark skin punk chuckled.

"I like to see you try. Come on." The red baggy hat punk dared Mio to try doing that little threat.

Mio was getting really uncomfortable with how these stupid men are trying to have their way with her like a defenseless girl, but she knows that she can't do anything or else she might blow her cover.

"Excuse, but I'm gonna have to ask you to leave my big sister alone." Izuku demanded, coming back with a bike.

"Oh, Izuku!" Mio surprised and relieved to see him back.

"Izuku? What kind of lame-ass name is that?" The red baggy hat punk asked, mocking Izuku's name.

"Better than whatever lame name you got." Izuku mocked back, trying to be brave for Mio.

That got the red baggy hat punk angry from hearing that and wanted to give a punch in that little brat's face, but never got the chance because Izuku thrust the palm of his hand to send the guy back and knock him down along with two of his friends.

"You little shit! You're going to pay for that!" One punk with a candy Jolly Roger angered.

"Oh my, what do we have here?" A girl's voice asked in a giggling tone.

Suddenly all the punks became scared feeling the shiver of fear going down their spines, they look like they're afraid of a ghost coming to them right now, and it's happening right now.

"Don't tell me that you naughty boys are pulling your shits again on an innocent girl." The girl walked up to the scene.

"Oh shit, it's Kimi Aoi!" The dark skin punk gulped in fear.

"Why did she have to come here, of all places!" The blue hoodie punk exclaimed.

"(Kimi Aoi, they're afraid of that girl?)" Izuku thought wondered.

"So, were you boys being naughty because I'll have to give you my Dancing Punishment." Kimi grinned.

Kimi is a girl with dark brown eyes and long wavy light brown hair that is adorned with lengths of white cloth, the length of the hair is all the way down to the legs and just above the feet. She is well-endowed and her figure is mature for someone of her age. She wears a violet color short sleeve shirt with a pink flower symbol on the front, light blue pants, and white shoes with raspberry color flower designs. Breasts sizes: K-cup.

"No, please don't! We weren't looking for any trouble! I swear!" The red baggy hat punk said, freaking out.

"Yeah, we were… Just leaving!" One ran for his lift and soon, the rest followed.

"(Whoa, is this girl like a big boss or something?)" Izuku thought amazed a little.

"I swear, those fools need to better themselves or else they'll find themselves with their cheeks very red. And I don't mean their faces." Kimi swayed her hips while walking toward the new faces.

"You're the new neighbors, it is very nice to meet you for today is your lucky day to be in the presence of Kimi Aoi!" Kimi greeted.

"Nice to meet you. I'm Izuku Midoriya, this here is my older adopted sister Mio Naruse, I guess you could say my stepsister as well." Izuku introduced himself and Mio.

"It is nice to meet you." Mio greeted.

"So, how did you know that we've moved here" Izuku asked.

"I live in the same neighborhood, so I would know about what goes on around here and I actually wanted to greet you all." Kimi answered.

"I'm also out here with a little friend of mine who wanted to get some snacks here." Kimi gestured at the small grocery store.

"Oh, and speak of the devil, here she comes." Kimi looked over to see a short girl coming out of the store.

"Hey Kimi, I'm done." The girl said.

"And just in time too, Philip! These two are the new neighbors, Izuku and Mio." Kimi gestured to the two new friends.

"Hello." Izuku greeted.

"Nice to meet you." Mio smiled.

"Hi, my name is Philip Burgundy, I do hope we can be friends." Philip greeted politely and bow at the two.

Philp is a short girl with white-like skin, short black hair and two bangs on each side longer closer to her shoulders, and brown eyes. She also wears a dark blue headband. Her clothing is consistent of a dark style dress with long and side sleeves, grayish white fur on the neck area, a black bowtie, black and purple pattern from the neck straight down to the skirt and little gold buttons, a three-point short cape with the same fur, brown legging socks with white ones underneath, and dark blue shoes. Breasts sizes: AA-cup.

"That's a cute outfit you're wearing, like a min-goth!" Mio complimented on Philip's outfit, finding her to be really cute.

"Thank you, it's my own style." Philip smiled, blushing a bit from the compliment.

"Anyway, thank you for saving us from those punks. I was thinking about having to make a run for it on the bike with Mio." Izuku thanked Kimi.

"You're very welcome. I always had to deal with those silly boys like them if they don't behave in my territory, otherwise I'd have to punish them." Kimi chuckled.

"Punish them. What are you, a Yazuka?" Mio asked shock.

"Maybe I am, maybe I'm not, that's a mystery you'll have to find out for yourself." Kimi winked.

"Well, what you guys do need to know is that Kimi is strong in her own way." Philip mentioned.

Izuku starts to become curious about this Kimi girl who seems like a very kind and exciting girl along with the beauty that others would go crazy for like her big breasts, but he can tell there is something else about this girl that makes her frightening to those punks to run away at the first sight of her.

And he found himself staring at her big breasts again, which he quickly shook his head.

"You know, you two might end up going to the same school we go to which means you'll be seeing a lot more of us around from now on." Kimi said.

"Okay, we'll look for you two once we get settle in our new house." Izuku nodded.

"Yeah, I would love to get to know you more and learn some things too!" Mio clapped her hands together.

"(Especially with how in the fucking world do you have such giant boobs?!)" Mio thought glared at Kimi's giant boobs. This reminds her of Izuku's mom, Sapphire with her own giant breasts.

"We better get going." Izuku said with a hand on Mio's shoulder.

"Bye." Izuku said as Mio is sitting behind him on the bike, and they ride away while Kimi and Philip waves goodbye to them.

"So, what do you think of them?" Philip asked.

"Those newly arrivals are certainly something. I don't know what that is about those two, but I can say for certain that things are never going to be the same from now on." Kimi smiled.

Izuku rides that bike through the streets taking the route back to the house to finish their grocery shopping, but the dark green hair boy has another idea to make this a special day for Mio.

"Hey Mio, I'm going to take you somewhere that you might like." Izuku said, confusing his older sister.

Izuku turns his bike onto another path while Mio is trying to think of where her new little brother is taking her. She was a little worried at first, but she brushes those worries away upon knowing full well that Izuku won't do anything hurtful to her.

After another few minutes of riding on the bike, Izuku stops and shows Mio a spot where they can see a very high place where they can see almost the entire town from this height.

"Oh wow, it's amazing!" Mio amazed of this place.

"Yeah, I thought of the same thing." Izuku smiled.

"I found this place after my moms showed me the new house, I wanted to know what the town was like so I would know where to go and see what it's like compared to my old home and that's when I found this spot. I don't think anyone else knows, not that I know of anyway." Izuku explained.

"It's a really amazing view, I was hoping to bring you, Maria, and our moms here to have a picnic together." Izuku said.

"Oh, that sounds nice." Mio commented.

"I know things are a little strange right now, being brought to a new place and living together with people you just met so suddenly which may seem scary, but I can promise me, and the moms are going to do whatever we can to make you and Maria happy in life." Izuku said.

"We'll b there for the both of you, always." Izuku said, taking Mio's hand.

"Really? You promise?" Mio asked.

"Of course, what kind of brother would I be if I didn't promise anything serious like family? No matter what happens, no matter the hardships and danger that may come out way, you'll always be important in this family." Izuku smiled strongly.

Hearing those kind and strong words from her new little brother has causes her heart to skip a beat almost like she was stunned; she felt warmth in her heart.

"Believe me when I say that we won't live your side ever!" Izuku promised.

(Nighttime, Home)

"You two are leaving now?" Izuku asked shock.

"I'm very sorry, sweetie. But my agent called in discovering that he mixed up the date for the shoot, we have to start doing it now and tomorrow." Raphaeline apologized.

"The gym called me in requesting to train some of their fighters for a last-minute of Hell training session before their big match. I'm probably gonna be gone for just as long too." Sapphire informed.

"Well, I guess there's nothing that can be done when it comes to the unexpected." Izuku commented.

"Don't worry, we'll be back before you know it. It's probably just gonna be a day, two at the most depending on how it is." Sapphire roughed Izuku's hair before giving him a kiss on the forehead.

"While we're gone, you're in charge of taking care of your big sister and little sister. We're entrusting the safety of this house in your hands." Raphaeline said, giving him a kiss on the forehead too.

The two women went into their car and drove off together as Izuku waves goodbye to them, and Mio watching the two mothers leave with a silent serious look.
