-A new fighter jet is born-

Off the coast of Okinawa-

A destroyer off the coast of Okinawa Anchoring is doing.

He seems to be holding his breath without even turning on the lights.

Suddenly, the sea surface rose near the destroyer.

The ship is a submarine, and the German Navy flag is flying on the bridge.

"Right on time. Lower the starboard boat."

A boat is lowered from the destroyer and heads toward the submarine.

Then the submarine's hatch opened and a sailor emerged from the submarine wearing a metal bag He came out with the book in his hand.

"Here are the blueprints for the Me262."

"Thank you for your efforts. Please convey to your Excellency the Führer that I am grateful for his kindness."

"Yes, I will convey this to Hitler. I wish our ally, the Empire of Japan, the best of luck."

"Yeah, I'm sure it's tough on the European front too, but do your best."

The sailor handed over the bag and disappeared with the submarine.

"So this is the blueprint for a jet fighter..."

A U-boat secretly departed from Germany carrying blueprints for the twin-engine jet fighter Me 262 Schwalbe to Japan.

The blueprints were transported in strict secrecy and sent directly to Yokosuka.

- Yokosuka Technology Development Headquarters -

"This is a jet fighter plane developed by Germany."

"Looking at the blueprint, I don't think it's impossible to make. However..."

"what up?"

"It is armed with four 30mm guns, which is quite powerful, but I feel the ammunition capacity is insufficient. Large bombers are expected to arrive in large formations. With this amount of ammunition, it may not be able to continue fighting."

"That's right, we'll figure out how to arm ourselves."

- Kawasaki Aviation Factory -

"Imperial Navy Technical Research Headquarters, Furukawa Lieutenant Commander."

"I'm Miura, the factory manager. Thank you for coming today."

"No no, so where is the important prototype?"

"I'll show you around. There are two planes parked at the adjacent airfield."

On this day, a new twin-engine jet fighter, the Me262, was waiting for Kato of the Technical Research and Development Institute at Kawasaki Airlines airfield.

"Any problems with the new model?"

"It's hard to say for sure until we fly it, but we expect it will consume a lot of fuel. I think it will be difficult to achieve the same range as the Zero fighter."

"Is that so? What about pilot training?"

"We have trained some excellent pilots, but today is the first time they've actually flown."

- Kawasaki Airlines Airport A -

"This is control tower, prototype, please check radio signals."

"Here Tachibana Lieutenant Commander. Radio reception is good."

"Got it, start the engines."

"Done, start the engines."

GGGGGG!!

The engine noise, completely different from any fighter jet I'd seen before, shook the surroundings.

The two engines mounted on either wing of the aircraft turned yellow, then gradually turned red.

"We've moved to the runway and are ready to go!!"

"Understood, Lieutenant Commander Tachibana. You are piloting a fighter jet that will carry the future of Japan. I'm counting on you. His Majesty has high expectations of you."

"Roger that, prototype taking off."

Lieutenant Colonel Tachibana pushes the throttle bar down with one swift movement.

The engines turn red and the plane begins to take off.

"Speeds over 300km/h, taking off!!"

Finally the plane took off.

It gains altitude with incredible acceleration.

"Altitude 500, 600... What incredible climbing power... The control tower reports that the prototype has reached an altitude of 1000. We will now begin test firing the machine gun."

The aircraft is equipped with a 20 mm No. 2 gun and a 12.7 mm Ho-103 machine gun.

Bang! Bang!

A heavy sound resounds as practice rounds are fired from the nose of the plane.

"Machine gun, no abnormalities."

"Roger that, return to base."

"Wow, this is a fantastic machine. I hope they start mass production right away."

"Got it. By the way, what would you like to name this fighter plane?"

"Well, Tachibana-kun, what do you think would be a good name?"

"Me?! I can't take on such an important role..."

"Well, then, after your name..."TachibanaKikka"How about "?

"Tachibana... Fighter Tachibana... It has a nice ring to it!! I'm honored!!!"

"Then I'll leave the fighter plane Tachibana to you, Kawasaki Airlines."

"Yes! Leave it to me."

Thus, the new fighter plane "Tachibana" was born.
