*Flashback-12 years earlier*

[Nishizumi Manor]-1545 hours

"Onii-chan Okaeri how was school?" said a soft but yet caring voice.

"Oh school is alright Miho-chan."

"Onii-sama hurry up lets play!" said a excited voice

"Ok what do you two want to play Miho-chan, Maho-chan?"

"Lets go ride around the tank!" said the two in unison.

"Alright sounds like a plan you two! Let's Go!" He said as he grabbed his two sisters hands.

"Don't take too long now, dinner will be soon" a fourth voice called out but this time it was loud and strict but you can see the love and worry underneath those caring words.

"Of course don't worry Oka-san I'll take good care of them and we'll be back before dinner" The boy said with a Big smile on his face.

One and Half hour later

[Nishizumi Manor]-1645 hours: Dinner Table

"Miho, Maho please go to your rooms now and prepare for Bed. Jiro, I need to talk with you privately" his mother started.

"Yes Oka-san, he said as he looks at his two younger sisters, Well you heard Oka-san you two get ready for bed and when I'm done here I'll join you two ok".

(As his two little sisters left the Mother and Son began to talk in private.)

"What do you want to talk about Oka-san?" he asked his mother.

"Jiro do you want to practice Sensha~do?"

"Yes Oka-san, it runs through our blood and a tradition of the family isn't it?"

"Well said my son but, you do know that here in Japan boys aren't yet allowed to enter the sport right?" his mother asked.

"Yes Oka-san, but other countries outside Japan permits Co-ed right?"

"Yes that's why were gonna proceed to the next questions that comes with it do you also to want further hone your skills and knowledge in Sensha~do?"

"Yes Oka-san I do so that my two little sisters wouldn't have to carry the burden of being heir of the family so they can enjoy playing Sensha~do with everyone" He said with the hint of care and determination for his sisters.

"Well then my son I got an offer for you, the offer is for you to move to Germany with your Father Tsuneo and you'll be attending school there starting next week until you finish, I've already talked with your current school and their fine with it and I've already completed the documents and transfer papers for you and your new school is just awaiting for your confirmation the name of the school is Westliche Kraft Universitat [Western Force University] their a prestigious university in western Germany that offers a Sensha~do course for both Male and Female students if you agree you get to practice Sensha~do overseas and further your skills but you'll be leaving Japan as soon as possible primarily two days from now, to settle in and move in a suitable housing for the both of you anything else want to add?" she asked her son with the hint of concern.

"I accept it Oka-san if it means my sisters to not carry the responsibility of the family forever then I accept but I want a different name so that I won't be treated like a VIP maybe a German borne name hmm?"

"Is that so then what name would you like so i can process the papers and coordinate with people"

"how about Eric Jager my story would go as I'm a Eurasian I could say that Dad is German or something and your Japanese, But can I tell this to Miho-chan and Maho-chan?" he asked his mother.

"No I'll be the one to tell them that at the right time because, they need to focus on their current studies and training I can't have them worry all the time, and they'll be emotionally affected by it but I'll be the one to tell them of you when the time is right for us"

"Ok I understand Oka-san I'll be going now" he said as he leaves the room.

A/N: Get it in the Anime each school has its own music such as Kuromorimine has Panzerlied or the St. Gloriana  is British Grenadiers, this will be the song for Eric's school its eastern sister university Tank song is below.

[Tournament Grounds]-Western Germany Finals 12 years later.

"Alle Panzer das ist Befehlspanzer Wir werden die Operation beenden" [All tanks this is Command Tank we are going to end the operation] he said in the radio.

"Jawohl!" the rest answered

"We are gonna finish this match early we are gonna do Betriebsfall Gelb"

[Operation Case Yellow]

"Jawohl Kommandant!" shouted the other commanders.

(He soon contacted his driver through the tanks internal radio and he started to lay out orders for movements.)

"Hans get us between Rhein two and four now!, Rhein two and four take care of the T-80's in front of us I'll take take care of the T-90" (Flag Tank)

"Kommandant shall I load the shell?" his Loader asked.

"Ja Werner load the APFSDS Anti Tank round we should be able to take them out at this range, Frau Wilhelmina I am taking over gunner since you can't yet hit targets at the range of more than 1200 meters"

"Jawohl Kommandant!" Wilhelmina said.

(As Eric Aimed at the enemy T-90 at the range of 1,950 meters according to his estimate.)

"Shell geladen kommandant!" Hans shouted!

"Stetig, stetig, Jetzt! [Steady, steady, Now!] he shouted.

"Brennen!" [Firing!] he added shouting.

*Bang* Goes the thunderous sound of the Rheinmetall smoothbore 120 mm L/55 gun of his Leopard-2A7

https://youtu.be/FYEQ_9Vjo9Y

Hint: skip to 1:57 for Gun action ;D And play Westerwaldlied it fits it

(Soon the 120mm shell travels at the T-90 at a range of 1,900 meters and hitting the target at its effective range and square on, thus white flagging it taking out the Enemy flag tank thus winning the tournament.)

"As expected of the Kommandant he really did seal the fate of eastern European university as ever" said one of the commanders.

"Ja, Wir haben gewonnen Herr Jager does it again!" [Yes we won!, Sir Jager].

"He's a really capable commander its like he is a Soldat [Soldier] already I wonder how he trains    himself" Said Otto Ludendorff the Vice Commander.

"Don't question it just accept the fact he's really good and he's been winning tournaments for us, for 12 years now and besides this is his last tournament since he's already graduating and Can't you notice Vizekommandant he is training you this past few 6 months to be his successor" Said one of his fellow tank commanders.

"Yeah I see it as well but with the Western Wolf leaving it can't be said that W.K.U would remain the same when he leaves but surely we can overcome the obstacle" he said with a smile.

(As the other Tankers chat away on their latest victory and a win of a tournament Eric was on his own on top of his tank thinking of what's ahead of him.)

"Finally my time is up, I can now return" he said softly at himself.

(The Team soon returned to the university but Eric was called up by the Headmaster of the university to talk with him on his office, he then proceeded to go to the office still wearing his Tanker Jacket he then knock on the door of the office.)

[University office Building]-Headmasters office

*Knock knock*

"Komm herein" was all he heard from the other side of the door.

"Du hast mich Schulleiter gennant?" [You called me headmaster?] he asked.

"Ah Ja, ich habe Herr Jager [Ah yes, I did mister Jager], Aber Konnen wir stattdessen auf Englisch sprechen? [But can we speak in English instead?] the headmaster asked.

"Sicher kein problem Schulleiter" [Sure no problem headmaster] he said.

"So what do you want to talk about headmaster?" Jiro began

"You are aware that this is the last week for you here in our university Ja?" he asked.

"Yes I know I'll begin packing now I'll be leaving once I got the awards and papers done".

"You want to continue serving the school for an extended period of time?" his headmaster offered.

"What are you offering sir?" he asked.

"I'm offering you a chance to try out to become an instructor" he said.

"But sir you do know that once I'm done with my studies here I'll be moving back to Japan right?" he interjected.

"That I know Herr Jager or should I say Herr Nishizumi, and do please let me finish my sentence before you cut me off" he said as he clears his throat. 

"I'm sorry headmaster, sorry for cutting you off won't happen again" Jiro Apologized.

"Good going back to my offer how about become an exchange Instructor from our school and you'll be sent to Japan as part of the Instructor exchange program? that is between Germany and Japan" he offered.

"So you mean I can still serve the school while testing out the waters to be an instructor as well as in Japan interesting" he said, while giving the offer some thought. 

"Well what do you say, and oh yeah the necessary papers and documents are ready to be given should you accept and don't worry about vehicle because your Father contacted me and sent me this handy Pay-check to buy out your current Leopard-2A7 for you, so you could bring it to Japan I just need your signature here *Hands Document* and the Tank will be yours to keep along with the Ammunition and oh don't worry about running out of Ammunition if you sign this and accept the offer on your first run you'll have a good amount of supply and just give me a call if you ever run out and I'll send a transport for you as well as spare parts from us its the best I can give, given you've been with us for nearly 12 years and given us countless victories on tournaments its my way of saying thanks to you personally". he said to Jiro.

"What about my crew they'll be graduating next year as well and I can't operate a tank alone if I'm gonna be instructing, plus my identity will be compromised sir". he asked.

"Well thought and yet you still are Eric Jager the legendary Western Wolf, for your crew I've already asked consulted them regarding this manner and they agreed to support you there during the duration of the exchange program and I've also consulted their families too if your worried about that, and its your discretion should you reveal your true identity to anyone else outside of family or very trusted individuals, well do you accept my offer?" he asked Jiro.

"I accept sir *signs tank document* then what transport i have to get my crew, equipment and Tank to Japan sir?" he said.

"Two days from now you'll meet your crew and equipment on our private airfield just a 1 kilometer from here there you will see our C-17 Globemaster III waiting for you, and you have a new uniform sent to your dorm. It would be your dress uniform wear it on official use only or when doing instructor duties along with two name plates one name plate is your cover name while the other one would be your true name should you reveal who you are, and your ribbons of course to show your merit and skill" his headmaster said.

"Jawohl!, is that all sir?" he asked.

"Yes that'll be all just give me a call if anything concerns you and I'll try at the best of my abilities to accommodate it"

"Thank you sir have a good day" he said as he exited the office.

(As he exited the office building he had a run-in with his crew or his friends and offered him to eat out with them on a nearby restaurant.)

"Wow Herr Jager here is taking us to Japan as part time instructors" said a over excited Hans.

"Calm down Hans your being too excited for the Job that the Kommandant accepted" said Werner.

"You just want to go there to meet Japanese girls do you?" Tease Wilhelmina with a grin on her face.

"S-Shut up! Wilhelmina just because you and Eric are dating you can tease me all the time" Hans said as he was blushing hard.

"Hey Kommandant heard what our sister university in the east are doing?" asked Werner.

"Nein what are they doing now?"

(Werner proceeded to grab his phone from his pocket and showed Jiro/Eric a video of their fellow university mates from their sister university and he then played it) 

https://youtu.be/RKxzdasGU0M

A/N: Replace the East German Flag with pretty much the same school emblem as W.K.U but the East German Markings remains.

"Its their team's official song and they're all using T-55A's and T-72's they really are echoing the Nationale Volksarmee there and they're being show offs on the topic" he chuckled.

"What's our teams response? I think our Social dept. Would cook something up by now".

"Well yes they did they used our Joint training video with the Bundeswehr" *he then plays a different video with the schools tanks on practice with the official song of the team*

https://youtu.be/yoh7Dnhq2RA

A/N: Replace the Armored cars and APC's and the SPAA's with either Leopard-1A5's and Leopard-2 series except the Leopard-2A4's seen on the video and also discount the Infantry.

"Heh the boys down a social dept. Always has always something to say to those buffoons" Wilhelmina chuckled.

"You can say that again" added Hans.

"Well that said come on guys I'm famished, I heard the food here is the best.

"Yeah you can say that Eric your gonna enjoy this place" said Werner.

(A an hour later the four of them finally retreated to their respective dorms to sleep and continue everything again tomorrow, and since Jiro would be taking care of the paperwork and some important documents as well as he gets to his dorm he received a call from his Father Tsuneo Nishizumi which is also in Germany he also notices his new dress uniform laid down at his bed)

"Yo Oto-san what can I do for you also its been a while how are you there in Berlin?" he asked his father through the phone.

"I'm good Jiro how's things there at Western Force? I've heard from my Mates here the famous western wolf wins again?" he teases.

"Hahaha yeah your right but its my final win in a tournament here in Germany how about you I assume you already know the Job I accepted?" he said laughing.

"Yeah I know I am the one who talked with your headmaster as a matter of a fact"

"I'm not surprised anymore. He said with the hint of amusement, So I'll take it your not coming home with me due to work right?" he asked.

"Unfortunately yes I can't come home due to my work but I'll continue to support you and I've already assigned someone back home to be your maintenance man for your tank"

"Good does Oka-san knows I'm returning?"

"No I did not tell her yet I think it would be better if its a surprise for her wouldn't it?" he said with a hum.

"Yeah your right Dad does my two little sisters know as well?"

"Unfortunately your mother couldn't bring herself to tell your two little sisters that their beloved older brother, left them due to the fact this will affect them emotionally and they won't be  focused on Sensha~do or their studies, so......." he said but he was immediately was cut off by Jiro.

"So she cooked something up regarding me saying I was just a random boy that stops at the house to entertain them or something, so in that place I'll be the one to tell them at the right time once I'm there and to be honest i could interact with them as a different person not as a brother yet so I could see how much they've grown over the past years is this correct?" he surmised

"Wow Jiro your intelligence never ceases to amaze me. he said with a laugh, And oh by the way how are things between you and Wilhelmina?" he asked

"Things are great given that once she knows who she's actually dating is from a prestigious family from Japan I wouldn't be too much surprised at her reaction and between the two of us everything is great and last month I got to meet her Parents at Kiel they're quite lovely people"

"Well I'm glad my son has turned into a very fine young man"

(As the father and son continued to talk away soon ending their calls to rest and with Jiro to run some errands on the morning he went to bed.)

Timeskip two days later

[Private Airfield]-Western Germany: 1500 hours

(At the Tarmac sits Eric with his crew and Tank decked out on their Tanker jacket just before them is the C-17 Globemaster III loading their Equipment and other stuff for the long journey to Japan they soon boarded and sat on their seats near the front end of the plane and soon they were now departing Germany to travel for 9,000 kilometers away half way around the world for nearly 12 hour flight.)

Boeing C-17 Globemaster III

A/N: Replace the U.S. Air Force with the Schools initials and on the tail is the logo of the school and to top it off replace the American Flag with a German one, also here's a C-17 Takeoff video to get the feel in the mood and now why i chose the C-17 cuz its more logical than use a bloody C-5 Super Galaxy that thing is just over kill for a Germany-Japan flight and the C-17 just has enough range to reach Japan and plus it can carry the gear and equipment and the single Leopard-2A7 since i did my research the C-17 can carry at least one Main Battle Tank so suck it.
