In 1963, Tokyo was being developed for the upcoming Olympic Games.

The city had just entered a period of rapid economic growth. The town was changing its appearance day by day.

A young man was packing at a boarding house in Kougai-cho, M-ku, Tokyo.

"It's a bit of a waste, but I don't think I'll use it in the medical school.

The object was an academic book.

"Let's see, General History of Technology, Compendium of Mechanics, Elementary Organic Chemistry, Sequences and Matrices, Basic Mathematics, Introduction to Mechanics, Introduction to Structural Mechanics, Materials Science, and Fundamentals of Fluid Mechanics. ......."

And then string them together.

"...... something like that. I don't know how much it will cost. Oh, I'll take these magazines too."

Talking to himself, the young man finished packing.

He wraps them in a furoshiki cloth and stands up, carrying them with him.

There was a bicycle in front of the lodge.

"Landlord, can I borrow your bicycle for a moment?

When the young man called out to her, a middle-aged woman looked out of the window.

"Oh, you must be Tsutsui-san. Are you going somewhere?"

To this question, the young man called Tsutsui replied.

"Yes. I was thinking of taking some books I no longer use to a used bookstore.

"A used bookstore, you mean ...... ah, the bookstore on the other side of the Kasumi-cho intersection."

Yes, that's right.

You're a doctor now, aren't you?

Yes, so I've got a lot on my plate.

Okay. I'll make you lunch when I get back.　I'll make some cold noodles and wait for you.

"Thank you very much."

Tsutsui started pedaling his bicycle.

He pedaled his bicycle along the foot of the huge park cemetery at the foot of Mount A in M-ku, Tokyo.

"This place has been developed so much. ......"

The streets have become much easier to ride since the asphalt was paved.

"Now, I wonder how much it will cost.

At the university he attended, the first and second years were the basic education course, in which students were required to study a wide range of subjects regardless of their department.

After the third year, he attended the Faculty of Medicine in S-Cho for four years.

He, Shuki Tsutsui, graduated from the School of Medicine this spring and became an intern.

He was going to sell some academic books (textbooks) to a used book store as he was not going to need them to further concentrate on medicine.

I went out from Kougai-cho to Ura-dori (back street).

Even though it is a back street, the street is much wider due to the construction work started last year.

It will be called in the near future.

Until then, it was a narrow road that passed by a cemetery and barely accommodated one car.

At night, even if you asked for a cab, it would only take you as far as the front of the street, which was a lonely place.

If you go along the new street and turn right at the intersection under the cemetery, you will soon come to the intersection of Kasumi-cho.

As a side note, the name "Kasumi-cho" is easily confused with "Kasumigaoka Danchi" which was built around this time, and cab drivers often made a mistake.

The young man was pedaling his bicycle toward the Kasumi-cho intersection.

Right next to the Kasumi-cho intersection, there is a streetcar line. It is called "Line 7," which connects Shinagawa Station and Yotsuya-Sanchome, and is the same line that Tsutsui Seinen uses to go to the medical school.

As he approached the intersection, he pulled his bicycle a little toward the streetcar in order to turn right.

With a roar, the streetcar came crashing down on top of the young man.

The cause of the collision was that a truck, ignoring the traffic signal, came running out of control from the upper right slope and slammed into the side of the streetcar.

Before he had time to scream, Tsutsui's consciousness was completely blacked out.

* * * *

"......"

Tsutsui regained consciousness.

He was surprised to find himself still alive, and wondered why nothing in his body hurt.

He gently opens his eyes and finds himself in a room he has never seen before, rather than in a strange ceiling .......

It is not the familiar ceiling panels of a boarding house, nor the dull concrete ceiling of a medical school.

"What the ...... hell is this place?"

I sit up, hoping that my body doesn't hurt.

What he was lying on was a bed. The bed was not covered with a sheet, but with short animal fur.

He gets up and looks around the room. There is no window. The room is furnished with what is called a sideboard, which Tsutsui thinks is strange for a hospital room.

Looking at his body, he finds that he is wearing only his underwear. His clothes were placed on a small table by the bed. .......

"...... are in tatters."

His shirt and pants were torn and ripped in some places.

I looked at my underwear again, and found that they were also very damaged.

"There's no blood on it. ...... but I guess this devastation means it wasn't a dream after all. ......"

I shudder as I think of the tram that came crashing down on top of me.

Just then, the door opened.

"**,＊＊＊＊＊＊?"

It was a woman who walked in, uttering unfamiliar words.

She was probably in her late teens. Her long, bright golden hair was tied carelessly behind her head.

Her eyes were emerald green. She has a few freckles on the bridge of her nose.

She is a little taller than 5'5". She is small in stature.

"Well, did you help me?"

"**?　＊＊＊＊!　＊＊＊＊＊＊＊"

"Kyanyusupi kuinguurikshu?"

"**. ＊＊＊＊＊＊＊＊＊. ＊＊＊＊＊?"

"Kanstudu duduichuushupurehiyun?"

"＊＊＊＊?　**,＊＊＊＊＊＊＊＊"

It seems that Japanese, English, and German are not understood. Tsutsui was at a loss.

At that moment.

"<>!"

A woman seemed to chant something.

!!!!"

Immediately after that, a huge amount of information flowed into Tsutsui's brain.

It was knowledge about the languages of this world.

"Did the magic of ......< work?　Do you understand me?"

"......Ah, ah. I understand. Just give me a few more hours."

Tsutsui, who had been overwhelmed by the headache-inducing volume of information, felt that with time the knowledge had taken hold and become his own.

At the same time, however, the term "send-info" magic caught his attention.

He was astonished by the fact that it was possible to give knowledge of another language in a very short period of time.

However, Tsutsui managed to suppress his curiosity.

"......Well, I've calmed down. ...... um, is this the right language?"

He tried to speak the language he had just learned. It was a language that sounded more like German than Japanese.

"My name is Shuki Tsutsui. What is yours?"

"Shuki Tsutsui?　That's a strange name. My name is Adriana. Is it correct that your name is Shuki Tsutsui?

"Yes, if that's what you mean, my name is Shuki. If that's what you mean, then my name is Shuki.

Shuki Tutuj. What's that?　......Tsutsui......Tsutsui......Tsutsui......Tsutsui......Tsetsi ...... Well, it's hard to call you, so can I call you Shuki?"

"Yes, please."

"Yes, please. You can also call me Adriana. So, Shuki, who are you?

This is a question that suddenly strikes at the heart of the matter, but even Shuki, Tsutsui Seinen...... does not know the answer to it.

I am a Japanese medical student. I will be 25 this year."

That was all he could say.

"Nihonjin?　Igakusei?　What's that?"

I knew he didn't understand me. Shuki explained himself in detail once again.
