Hello everyone it's time for a new chapter. Last chapter the girls decided to do a competition of who would please you the most since it was your birthday. After the birthday party you were walking back to your dorm and a girl who calls herself Madoka (L/n) stops you and tries to shoot you.

~~~~~

POV: You

Part 1.

Madoka pulls the trigger but before she could fully pull it I summoned Queen to block the bullet. It wouldn't off if people started waking up from the gunshot and looking at the commotion, but that's if anyone did hear it. I then summoned Heart and pointed it at her without hesitation with Queen in my left hand.

"Who are you really?" I ask her.

"What do you mean?" She questions "I'm your sister, Madoka (Y/n)"

"That's impossible" I tell her "I've never heard that name in all my life and you don't look familiar to me. Alexis has never spoken about me having a 2nd sister"

"I see" Madoka says with a twitch in her lip "I guess she brainwashed you to make you forget about me"

"Who is this 'She' you keep talking about?" I ask her.

"Our sister Alexis (L/n)" She tells me.

"Like I would believe a member of Phantom Task" I say "How would I know if your just saying what you've been saying just to get into my head"

"You wouldn't...." She says "But I guess you might never learn the truth because of the bitch" She shouts before pulling the trigger of her gun.

I put Queen in front of me to block the bullet from her gun. I look out from behind Queen and I didn't see Madoka in the light of the lamp any more. I look up and I see Madoka piloting SIlent Zephyrus in the sky. I looked at Madoka's half covered face and I see what look like a tear go down her face.

"Why did it have to end up this way?" I her Madoka ask herself before flying off into the distance.

I desummon Queen and Heart then I started waking. I just kept walking around in a loop on the stone path I was walking on trying to wrap my brain around this whole incident. I couldn't understand any of this like if madoka was really my sister then why do I not remember her and why come Alexis has never said anything about me having another sister.

"God damn it!" I shout "None of this makes any sense. I guess the only person that can explain this all is Alexis"

I then started walking from where I was to Alexis's office where I assumed she would be there. As I walked I had this sense of anger inside of me, wanting to know if this was all true why keep it from me. When I got to Alexis's office I saw her door partially open, through it I saw Alexis doing work at her desk. I knock on the door with the back of my hand as I opened the door and entered her office.

Alexis sees me and says "Hey (Y/n), what do you need?" she looks at my eyes and she senses that there is something wrong "What's wrong (Y/n)?" Alexis asks with worry in her voce.

"We need to talk" I tell her as I closed the door to her office and locked it.

"About what?"

"Do I have another sister?" I ask her.

She looked taken back by my question before responding "I don't know what your talking about. I'm your only sister"

"Not from what I've been told" I say "Now tell me, Do I have another sister yes or no?,And you better not lie to me" I shout with anger.

"Y-yes...." She says while looking away from me.

"What's her name?" I ask her.

"M-Madoka" She says.

I then remembered something I saw earlier this morning. I pick up the picture frame that dropped on the floor this morning and opened the back up and pulled out the torn part of the picture.

"This is Madoka isn't it?" I question her as I showed her the picture of the baby with black hair.

"Yes it is" She answers.

I start to calm myself down and sit in the chair that was in front of her desk then put the picture of madoka back in the frame. I lay back in the chair and I ask Alexis after all of the anger went away.

"Why can't I remember her?, Why can't I remember having a sister named Madoka"

"It's because of something that happened when we first moved to Japan" Alexis says "There is a story I need to tell you now that you know"

"A few months before you were born our Dad left our Mom because of something I didn't understand at the time. Soon after that Mom found someone new while she was still pregnant with you. She resented me and you just because we had our Father's blood running through our veins. Mom hated him for leaving her. So when you were born Mom wanted a kid to raise that didn't have to deal with our Dad, So when she heard from a nurse about a baby that was abandoned at the hospital Mom was overjoyed and begged her new boyfriend for the baby until gave in. Her new boyfriend accepted us as his own children despite having our Father's blood. As the years went on from that day forward our own mother did her best to torment us, But you and Madoka were like best friend, More than a brother and sister bond. Mother didn't like you around Madoka but Madoka was always happy around you so she let it be.When I was 15 I was discovered by Tabane and was told that she wanted me to help her with her IS project due to my athletic abilities at the time. So I took that chance to escape with you to Japan, but I couldn't take Madoka, I knew mom would hunt me down for taking her with me. When the time came I took you with me and we left the United States for Japan. It wasn't soon after arriving in Japan that you noticed Madoka wasn't around, and that's when it happened.It was about 2 weeks after arriving in Japan. Me and you, were with Tabane in a Isolated field away from people doing some tests on the first IS Tabane made. "Alexis explains.

"You mean-" I say while realizing something;

"Yes, I was the pilot of the Shirokishi" Alexis admits.

"This was a little bit before I met Chifuyu and you became friends with Ichika"

{Flashback}

POV: Alexis

It was bright outside and I was doing tests for Tabane while piloting Shirokishi. The area where we were was a isolated open field. There were military personnel watching the surrounding area. I was standing by the small mobile command vehicle that was brought along to help out with the Tabane's testing. Tabane plugged in a wire into Shirokishi and then started typing away at her computer inside the command vehicle. (Y/n) was sitting in a metal couch like seat that had cushions on the back and bottom. He stayed quiet this entire time during the testing today, most of the time he would want to help out as much as he could and sometimes on breaks Tabane would want to play with him. He was only 6 so there wasn't much he could understand about what is happening and what happened. He warmed quickly to Tabane even for only meeting her 2 weeks ago.

"Alexis-chan, what's wrong with (Y/n)-kun?" Tabane asks me "He doesn't seem happy"

"I don't know what's wrong, he's been like this ever since he woke up" I reply.

"Do you think it could of been a dream or a nightmare?" Tabane questions.

"It's a possibility" I say.

Tabane finishes typing then gets out of her chair and unplugs the wire "I need to go check something in the garage truck" Tabane says before jumping out of the command vehicle.

"(Y/n), what's wrong?" I ask.

"Big sister, When will I be able to see Madoka again?" He asks me.

I felt guilty inside because I took him away from his best friend. I kneeled down to the back of the command vehicle in front of the doorway.

"(Y/n) come over hear" I say and (Y/n) stands up and walks over to me "I don't know how to say this but I don't think you will ever be able to see Madoka again" I tell him the heartbreaking truth.

(Y/n) then starts to cry "Why is that big sister?" he cries out.

"B-because I took you away from her, She's back in the U.S. and we're in Japan" I tell him.

"Why would you do that big sister?" He cries then starts hitting my chest "Why would you take my best friend from me big sister? Why!"

I pull him into a hug and (Y/n) resisted for only a short time before easing into the hug. He continued to cry until he just stopped, he didn't do the slow process of crying then weeping then whimpering before stopping, He just stopped out of nowhere. (Y/n) touches his face and feels the tears before looking up to me.

"Big sister? Why am I crying?" (Y/n) asks me in his normal voice.

"Do you not remember what we were just talking about?" I ask him.

"Nope" He says.

"What the heck just happened, why does he not remember why he was crying?"

"(Y/n), Who am I?" I ask him to test something.

"Big sister Alexis, The best and only sister in the entire world" (Y/n) says while hugging me happily.

"He doesn't remember Madoka, like all of his memories of Madoka were wiped. I need to test something else to confirm this"

I unwrap (Y/n)'s arms and set him in front of him "(Y/n), When is your birthday?" I ask.

"I-I don't remember" He says with his finger on his chin thinking.

"I guess I was right, I need to talk to Tabane about this"

"Okay (Y/n), I need to get back to work okay" I tell him.

"Okay" He says with a smile before sitting back in his seat happily.

"If your good Tabane might play with you while were on break" I tell him.

"Yaay" He shouts in his seat.

I then walk over to the garage and found Tabane tinkering with something in the garage vehicle. I didn't know what it was that she was working on. Tabane notices me and says.

"Hey Alexis-chan, How did it go with (Y/n)-kun?" Tabane asks me as she held a wrench.

"Yes and no, It seems he forgot about his other sister that's back in the U.S. out of the blue. He was down because he wanted to see her" I tell Tabane.

"Hmm" Tabane says as she starts thinking "He might of forgotten her because of Shirokishi" She guesses.

"What are you saying Tabane?" I question.

"What I am saying is that Shirokishi might of wiped his memory of his other sister" Tabane tells me.

"How can that even happen?" I ask with surprise.

"The core of the IS has its own personality just like every other IS that will be made. Shirokishi must have a personality of valuing things and wanting to protect the things it and the pilot value most. Shirokishi must've taken a liking to you and (Y/n)-kun and value you and him the most. So Shirokishi probably sealed away all knowledge of his other sister to protect him from being hurt for the rest of his life and maybe hating you" Tabane explains to me.

"Will (Y/n) ever regain those memories?"

"I can't say if he will or not, but I'm predicting that he won't no matter how hard you try to get him to regain them" Tabane says.

"Huh, I feel guilty that this happened to him. Now he won't remember anything about his best friend that he made so happy" I say.

"Hey don't be so down Alexis-chan, I'm bringing in someone new soon to work with me and I heard that she has a little brother also thats (Y/n)-kun's age and I also have a little sister that's also his age. We could send all three of them to the same school when the new school year starts up" Tabane says bringing me up again.

"That would be great" I say with a smile.

"Though at some point the military might make my sister move when the IS becomes more and more popular" Tabane says "But he will be able to gain a childhood friend in the end" Tabane adds.

"That's good" I say.

"Now, let's get back to the testing" Tabane says.

{Flashback End}

POV: You

"That explains a lot" I say as I sat back in the chair not knowing what to think about Alexis' story.

"I'm sorry that I didn't tell you about this sooner. I thought it was a good idea if you I never told you about her once you memory was sealed" Alexis says.

"It's okay, you did it for my own good" I say "So where is the core of the Shirokishi now?" I ask.

"Inside Silver Ace" Alexis answers.

"Wait what?" I question.

"You see, The personality of the core of the Shirokishi valued the both of us so much that one time when Tabane wanted Chifuyu to use it for testing Shirokishi didn't even want to move" She explains.

"So your saying the reason why I can pilot Silver Ace so well is because the core of the Shirokishi is inside it?"

"Correct"

I lay back in my seat with my head laying back so I could look at the ceiling in thought.

"I wish I could remember all the things about Madoka that I forgot" I say.

My necklace then starts to glow brightly before emitting a bright light and flashing the room with a white light. I then start seeing flashes of images and small snippets of memories of me with a girl in black hair who always had a smile on her face. So much information was flowing back into me. Then it all stopped.

Part 2.

I was laying down somewhere and I the feeling of tiredness was waying heavy on me.I open my eyes and I sit up before rubbing my eyes.I look around and I see myself in the school's infirmary, I was in the bed that was right next to the big window. The light that poured through the window of the infirmary was orange and was plastering the room. I look to my left and I see Houki, Cecilia, and Rin laying next to each other sleeping on the infirmary bed next to me. In front of that bed was a cushioned bench  that had Charlotte and Laura laying on it sleeping. They were all in their uniform. Then I started to a pain in my head.

"Damn my head hurts" I say.

Houki hears me and she starts waking up before rubbing her eyes. She then sees that I'm away and her eyes widen a bit then she jumps onto me and hugs me from the side with both arms.

"Oh my god you up, I so happy you're awake now" Houki says as she hugged me tightly.

The other girls then starts waking up.

"Houki keep it down, we were trying to sleep" Cecilia says while rubbing her eyes.

"Yeah, what is the big deal with the noise" Rin adds.

"Is there something wrong Houki?" Charlotte assk as she yawns.

"Is my bride up yet?" Laura asks groggily.

"He's awake guys, (Y/n)'s awake" Houki tells them.

They fully open their eyes after getting out of their sleepy state and look at me. They then jump onto the bed and they all try hugging me tightly.

"My bride you're finally awake, I was so worried" Laura says.

"You mean we were all worried" Rin corrects her.

"Wait, what do you mean by finally?" I question.

Before any of them could reply Alexis and Chifuyu enter the infirmary and see all of the girls hugging me at the same time.

"You've been out for the past 3 days" Chifuyu states.

"When we were talking in my office you just suddenly became unconscious" Alexis says.

The girls then started letting go of me and sat down where they were laying down

"I see" I say then said something without thinking "Madoka (L/n), My second sister that was born on the same day that I was"

The girls just stared at me including Chifuyu.

"You have another sister!" The girls shout almost ruptering my ear drums.

"Yes" I say "And she is working with the organization that attacked the school on the day of the festival"

"Which pilot was she?" Charlotte asks me.

"The pilot of Silent Zephyrus" I reply.

"So what are you going to do if they attack again and she's with them?" Laura asks me.

"I'm going to bring her to our side" I say.

"How are you going to do that?" Houki asks.

"Not sure, but I'll figure it out when the time comes" I say "Right now my head killing me and I'm tired, I'm going to sleep"

I then laid down and closed my eyes, the other girls had other plans for me to do.

"Ohh no you don't, you just woke up" Houki says while trying to pull the blanket off me.

I then feel someone get under the blanket and lay next to me. I open my eyes and see Laura laying next to me.

"And what are you doing Laura?!" Cecilia shouts.

"I'm going to sleep with my bride, isn't that obvious?" Laura says.

"Then I'm getting in too" Rin says while jumping into the infirmary bed.

One thing lead to another and all 5 girls were laying on my infirmary bed with me. I sigh and accept it before closing my eyes.

POV: Alexis

Me and Chifuyu watched as (Y/n) and the girls laid on the same bed sleeping. I smiled to myself and some good memories came back to me of when Mom had to go on her business trips and our step dad allowed us Me, (Y/n), and Madoka all sleep together in the same bed. It made him and us so happy.

"Those were some good memories" I say in my mind.

"What are you thinking about Alexis?" Chifuyu asks me.

"Just some memories from back when we were younger" I say.

"I see, we all have those now don't we" Chifuyu replies before walking out of the infirmary.

"I wish it could go back to how it used to be between the three of us"
