Location: Mobile scanner No.4

Over the past year since the very first Kanmusu appeared, there has been many more that have shown up. As a result of this bases around the country, both active and deactivated, have become home to the kanmusu Fleets, Thus allowing them a greater area of operability in order to push back the Abyssal threat.

With the amount of fleets that have appeared over the past couple of months, that still did not stop people from going to either a testing center or a mobile scanner in order to see if they are viable to become a Kamusu.

We now join mobile scanner No.4 on a routine patrol run in the Minami ward in Yokohama as they start looking around, scanning for potential Kanmusu in waiting. But so far luck has not been on their side.

'This really isn't going well' I said to myself sighing as I took a right turn at an intersection to head into the next scanning zone.

Hi there my name Aria Miyanaga, I have royal-blue hair and brown eyes, I'm 35 years old and standing at an above average 5'4". I'm currently on the clock performing my duties of what's known in naval terms a scanner, basically we go around and look for people who can become Kanmusu and we do this via the core we have stored in the back of the van.

Now as to which ship fragment the core contains, we have absolutely no idea. We usually find out after a person has become a Kanmusu, not before which was really strange in retrospect.

"Can't this day go any faster, I'm dying of boredom over here" A voice said gaining my attention.

The person that the voice belongs to is a childhood friend of mine. She goes by Maxine Kanzashi, or Max for short. She is the same age as me and has strawberry blond hair and red eyes. She also stands at 5 foot even.

"Come on Max, we only have one more zone to cover. I'll buy you dinner if that helps" I said

"I'm holding you to that Aria" she responds

It was about half way through the zone and we were waiting at the next set of lights, it was at this point I sighed gaining the attention of Max.

"What's wrong Aria?" she asked

"I miss my fleet" I replied

"Come on, don't worry Ryuujou has a handle on everything"

"I guess, but I'd rather be there rather than being stuck in this van"

"I hear that"

I bet you are wondering what I mean by fleet, well I'll tell you. I'm an Admiral of my very own fleet of ship girls based out of Sado Island on the west coast of japan. Now I bet you are also wondering why an Admiral like myself doing in a scanner unit, well I got the short end of the stick.

You see we had a gathering of Admiral's down at HQ but a call came in for a 2 man unit to be made up to take over the scanner route due to the previous team being suddenly reassigned. So we decided by pulling straws seeing as the meeting was going to start soon. Who would've guessed that me and Max both lost and well here we are on patrol.

"Oh, scanner's got a hit. A couple of streets away" Max said

"Well, let's get going then" I replied increasing the speed of the van

It took up ten minutes before we arrived at the destination. When I saw where the scanner had led us I went wide-eyed in surprise….

'This is nee-san's house…. no way' I said to myself as Max pulled out her binoculars to get a look

"I see two girls, the scanner is being weird at the moment so I can't get an accurate reading on which one of them the core is responding to"

'Two girls huh…. haha it seems my dear Nephew had been tricked by Yoko into wearing girl's clothing again. Thank god I'm not getting involved, yet.' I said to myself watching the two of them run around the front yard.

"Get back here"

"Catch me if you can, nee-chan"

"That's nii-san to you damn it, stop running away"

"Not when you're wearing that sundress, Nee-chan"

"Damn it!" I roared

I guess I better introduce myself huh. Well my name is Fumio Yamaguchi and I'm 17 years old, I have neck length silver hair, I also have what's known as a heterochromia with my left eye being blue and my right eye being yellow and I stand at 4'3". Yes I'm a Chibi *sighs* for whatever reason my development left me in a position that from a glance most people confuse me for a small girl.

I just can't understand why I developed the way I did, as a result I'm constantly teased by my younger sister. Who by the way is the main reason I'm currently wearing a sundress as I lost in an unexpected game of jan-ken-pon.

This really got me annoyed and caused me to start chasing her around the house and eventually the front yard. Anyway meet my younger sister Yoko Yamaguchi, 15 years old, has waist length blue hair and blue eyes. She also stands slightly over the average height at 5'3". With her height advantage she towers over me and she uses her height to constantly get on my nerves with her constant teasing.

But beneath her teasing surface I know she cares for me deeply, due to the fact that I raised her on my own most of the time because Kaa-san was always busy at work for most days and only came home when she had time off.

I was starting to slow down so I took a break to catch my breath but I slipped up because I gave my nee-chan a chance to tease me, to which she readily did….

"Come on slow coach" Yoko yelled pissing me off even more

"That's it!" I roared and resumed the chase.

'Haha…. it seems some things never change with those two' I said to myself. It seemed to me that Max was still trying to pin down which of the two the core was reacting to.

'It has to be Yoko, I mean Fumio can't become one because he's a boy…. I think'

"Hey Aria can you check on the core for me I think I heard something back there" max says snapping me out of my thoughts.

It was then I could start to hear some sounds coming from the back of the van, so I got out and went to open the rear doors and what I saw surprised me greatly. The core that we had been given was behaving erratically in its container unit and it was getting worse by the second. All of sudden the container broke and the core started to levitate and it then quickly sped off punching a hole through the side of the van.

I ran around the side and caught the direction the core was heading and I saw that….

'Shit, Fumio!' "Hurry Max we got to get over there" I yelled as I started running with Max running not to far behind before going past me.

I had noticed that Fumio had taken another break and so I decided to turn around and tease him again. But as I did so I noticed a bright blue object flying quite quickly in our direction and to my horror it hit Fumio square in the back causing him to face plant into the ground.

"Fumio?" I called starting to panic "Fumio?" I asked once more as I got closer to him. All of sudden a energy blast came from Fumio's direction knocked me clean off feet and sent me straight into the fence causing me to seethe in pain. It was then that my panicked state skyrocketed and I roared "FUMIOOOOOOOOOOO!"

I then watched as he stood bolt upright and I heard him roar in pain, I knew at this point that something bad was going to happen. Oh man I wished I was wrong about this.

Changes were happening to Fumio, slowly at first starting with his hair getting longer to mid-back length. It was then that the changes rapidly increase their pace, his overall body shape had become far more feminine, with places thinning and expanding. His voice had become far higher than it was as he continued to roar in pain. The last two changes made sure that Fumio was completely female as an emptiness was now between her legs and lastly her chest expanded to fit her new frame perfectly causing the sundress she was wearing to fit even more snugly.

I can't believe what the hell I just witnessed. I just saw my older brother become my older sister, he had become a girl!. I knew the cause of this was that blue light and it seemed that for now the transformation had stopped. But deep down I had a feeling it wasn't finished.

"Fumio?" I asked once more as I approached her, but then out of nowhere four large turrets that looked like they belonged on a tank appeared on her back. I started to get worried again as I saw that the turrets were connected by what seems to be a funny looking x-brace with flat bits under the turrets. From there they were attached to her back by the top half of a racing harness. I couldn't tell if there was anything attached to the rear of what Kaa-san calls an outfit, because I couldn't see anything.

Instead what I saw was a huge amount of what seemed to be fairies that were flying around her body, which kind of freaked me out a little seeing as I've never seen them up close before. Fumio then opened her eyes and looked at me, saying "Nee-chan" before passing out so I rushed out to catch her. Luckily the turrets vanished just as I stopped her from hitting the ground.

Thankful that everything was over my emotions finally took over and I started to cry as I stroked Fumio's hair, wondering why the hell this had happened. It was then that a voice spoke up.

"Holy shit, that was violent" I turned to where the voice had come from and I saw a strawberry blond haired woman, now what she said pissed me off so I retaliated by saying….

"Of course it was freaking violent you goddamn idiot, that blue light just caused my big brother to turn into a Kanmusu for fucks sake!"

"Not a snowball's chance in hell, there is simply no way a male can become a Kanmusu" the woman stated

"Yoko's right Max, Fumio is my Nephew" Another person said and I saw that It was Auntie Aria that had walked up beside the other woman

"No way" she replied going wide-eyed in shock

"There is no time to waste, Max get the van over here pronto" Auntie yelled

"On it" the person named Max said bolting off somewhere

"Yoko"

"Y-Yes"

"We need to get Fumio to the Naval hospital ASAP, who knows what else could have happened to him during his change into a Kanmusu"

I then picked her up in a princess carry and as soon as Max-san showed up in the Van, I went into the back and placed Fumio down gently placing a blanket over her.

Auntie then got into the van and drove as quick as she could before speaking to me

"Yoko, get a hold of your Kaa-san she needs to know what happened"

I replied by pulling out my phone and dialing Kaa-san number but….

"Shit! Auntie she's not answering what do we do!" I yelled

"Damn it all, Alright calm down Yoko I'm calling it in" Auntie said using her laptop to to initiate what seemed to be a video call.

Location: JMSDF HQ, conference room

'I'm glad that's finally over' I said to myself. Hello my name is Emika Yamaguchi, I'm 36 years old and have mid-back length dark blue hair and I stand at 5'6". I'm also the mother to two wonderful children, a boy and a girl well *giggles* more like two girls seeing how much Yoko teases Fumio by making him wear female clothing most of the time.

Anyway I bet you are wondering why I'm here, well It's my job to be here. Seeing as I'm the current head of the Japanese Kanmusu program. That's right I was chosen to make sure that the program runs smoothly and thankfully it is. Now today was an Important day because every two months the Admiral's of the various Kanmusu fleets get together and basically we update each other on how our fleets are doing.

Now we mainly do this via secure video calling, but seeing as every admiral was here with their secretary ship girl. We just decided to host it here in the HQ. Now I was about to end the meeting when suddenly a call popped up on the main screen….

'I wonder what nee-chan wants, maybe something happened' I said to myself as I accepted the call and I saw Aria-nee looking pretty worried.

"What is wrong unit 4, I was about to dismiss the meeting" I said

"Stop with the formality crap sis and get your ass down to the Naval hospital ASAP" she yelled "It's Fumio" she continued to say causing me to realise something was really wrong.

"What Happened Aria!" I yelled

"Your son, Fumio has turned into a GODDAMN SHIPGIRL!" she roared

"Bullshit!" one of the other Admiral's said, it was then that Aria played a video confirming what she had said. Fumio turning into a ship girl.

"That's was almost half an hour ago sis. Yoko is in the back crying her eyes out and I'm here going as fast as I can scared out of my wits for the welfare of my Nephew. So what the fuck are you doing sis hurry up and get a move on!" She said before ending the call.

I Immediately jumped out of my seat and rushed out of the room, calling for my secretary ship to follow me.

"Zuihou, fetch a car now!"

"Yes Ma'am" she replied running off to the car pool whilst I grabbed a few things from my office before heading out to the front of the building. It didn't take long for Zuihou to show up in a jeep and I hopped in

"Quickly to the hospital, Zuihou"

"Ma'am!" she replied before she put her foot down and we sped off

'Hold on Fumio, Yoko I'm coming!"

Time: 11:30

Location: Yokosuka Naval Hospital

As soon as we pulled up to the entrance of the hospital, I hopped out and went inside with Zuihou not too far behind me. I started to look around when a voice got my attention.

"Kaa-san!" I looked over to where the voice had come from and saw Yoko sitting down in a chair, crying her eyes out, with Aria and Max across from her. As I got closer to them Yoko Jumped out of her seat, ran over and hugged me to which I hugged her back. Before looking over to Aria and asked

"Fumio, where is he?"

"First take a deep breath sis" she said to which I complied "Good, now don't worry Emika. Fumio has been taken to the Kanmusu wing and standard protocols for new ship girls have been carried out, so all we can do it sit and wait"

After she finished talking I looked over at the clock and saw that it was close to lunchtime. So I decided to take everyone over to the conference room in the Kanmusu wing. When we all had arrived and ordered some lunch, I asked the three of them to retell what had happened to Fumio from their perspectives in order to reinforce what I had seen in the video from earlier today. They happily obliged and told me what had happened.

It was now half two in the afternoon and after we had eaten we made some small talk before boredom had settled in and we all sat there trying to keep ourselves entertained. It was then that finally a video call came through and we all saw Doctor Mizu, a 28 year old red haired woman, who was our resident Kanmusu expert and hopefully she had some good news.

"How is she Mizu" I asked

Mizu then went on to explain that apart from the pain Fumio had suffered from the transition from male to female and then to Kanmusu, she was a perfectly healthy 17 year old girl. In fact she was so healthy that Mizu was in a state of shock. Now even though that she was a Kanmusu now and she had gained all of the quirks of becoming one, Mizu assured us that she would be the same as she was before.

This caused the four of us to sigh in relief that Fumio would be okay, but a question then popped into our heads….

"Mizu, did you figure out which ship fragment was contained in the core" I asked

"Yes Emika I did and lets me say it's a doozy of who Fumio has become" this caused us to become confused as to what she meant

"The fragment has been designated as Battleship A150" she continued to say

''''Battleship A150!'''' the five of us yelled in unison.

"For fuck sake, I really wish I had brought Yamato with me" Aria moaned

"And why is that?" Zuihou asked with the rest of us becoming curious as well

"Back during the war, there were two ships with the designation of A150 and A151, those two ships during the war were based on the Yamato-class given the term of Super-Yamato class, seeing as the both of them surpassed their sister ships in terms of firepower. The two of them were loaded with the largest guns of any warship of the time" She paused to take a swig of her drink before continuing

"Both ships had 8 510mm cannons in groups of two in four turrets making them one hell of a deadly force to be reckoned with and now that Fumio has come into contact with the core…."

"My big brother has become A150 and as a result I think that she has become the most powerful Kanmusu to date. Am I right in saying that Kaa-san?" Yoko asked me

"Yes my dear that is exactly right and with that said, we now have another problem to deal. What are we going to call my daughter?" I asked

The six of us then brainstormed for a good fifteen minutes, throwing names left and right. But in the end we were going nowhere with deciding on a new name for her, so we all decided that we'll ask what she wants to be called when we go and see her.

"Mizu is it alright if we go and visit Fumio?" I asked

"Sorry Emika, everyone but I would advise against for now, the reason being is that Fumio is currently in a heavy sleep due to exhaustion from the day's events. It should be okay to visit her tomorrow though when she wakes up" she replied

It sucked that we couldn't see her right away but we were happy that Fumio was in good hands with Mizu watching over her. So we ended the call and then left the hospital, all of us then somehow crammed into the jeep and we made our way to a nearby hotel and checked in for the night. All I could think about as I drifted off to sleep, was how well Fumio would handle everything when we visit her tomorrow. I guess we'll all have to wait and see what tomorrow will hold.
