2. Transference to Another World

“Sir… sir?”

Suddenly, a bell-like beautiful voice echoed in my ears. It was a voice that I wanted to keep hearing, resonating with even more melodious tones.

“Perhaps now, without being noticed, I can do various things… N-no, I must hold back for now… Sir, please wake up, sir!”

This time, it was a slightly urgent voice. Though I felt a bit disappointed, my consciousness gradually floated to the surface.

This voice… it’s Isezaki-san.

Ah, I was stabbed with a knife… The knife wound cleanly disappeared, and then—what happened again?

I finally opened my heavy eyelids. Close by, there was Isezaki-san’s worried face and a soft sensation at the back of my head. It seems I was being used as a pillow by Isezaki-san again.

I thanked Isezaki-san as I sat up and looked around.

The surroundings were mostly devoid of vegetation, with only barren land stretching as far as the eye could see. It was like the desolate wilderness of Mars I had seen in photos before.

“Isezaki-san, why am I in a place like this? Um, where is this exactly?”

In response to my question, Isezaki-san answered quietly.

“…Probably… we’re right near the frontline city of Grandain.”

“Frontline city Grandain.”

I’ve never heard of such a town or village. Not understanding the meaning, Isezaki-san nodded earnestly at my parroted response.

“It’s dangerous to stay here. Let’s move to a different location right away.”

“Y-yeah. But, um, where exactly are we?”

“The frontline city… well, yes, that’s right. But that alone doesn’t tell us much, right? This place is… in other words…”

“In other words?”

“…It’s another world.”

“Another world.”

I had no choice but to parrot again. As I was speechless, Isezaki-san stood up while brushing off the dirt from her skirt.

“I regained the sacred power of the Great Saintess, and with that power, I healed you, who was on the verge of death. And then… for some reason, it seems like you and I were transferred to another world.”

“Um… When I was a student, I read some isekai light novels, but is this what they mean by another world?”

“Haha, yes. That’s exactly it.”

Isezaki-san answered with a chuckle. It seemed genuinely happy that I understood.

Her smile was pure, and it didn’t seem like she was trying to deceive me or play a prank. I think we have that level of trust between us.

I and Isezaki-san were transferred to another world—apparently, that’s the only thing to believe in.

—

As we walked towards a relatively safe town, Isezaki-san told me about this world first.

—It’s a story from over ten years ago now, but Isezaki-san lost her parents in a traffic accident.

Their car collided with a drowsy truck that had veered off the opposite lane on the highway. At that time, Isezaki-san, who was five years old, was in the car with her parents.

The bodies of her parents were found from the car that caused the accident. However, Isezaki-san alone was not found.

For a while afterward, the search for Isezaki-san continued. However, since there was a river flowing very close to the highway, it was speculated that she might have been thrown there, making the search even more difficult, and it was eventually called off.

And then, about six years later, a girl who had been taken in by a police station called Isezaki-san’s grandmother. That girl turned out to be Isezaki-san, who had been missing for six years.

Her hair, which was black at the time of her disappearance, had inexplicably turned silver, and she had no memory of the six years of blank space. However, through questioning and DNA testing, it was confirmed that she was indeed Isezaki-san, who had gone missing in that accident. From then on, she lived with her grandmother.

The collision accident involving her parents was covered in the news, but Isezaki-san’s return did not make it to the news. I heard that this was because the police officers who were close to the Jounai family were working behind the scenes to make it happen. By the way, Isezaki-san’s real name is Seina Jounai. She is the daughter of one of Japan’s leading conglomerates, the Jounai Conglomerate.

Certainly, in this day and age, it’s conceivable that she would be exposed if she used her real name. So, her grandmother changed Isezaki-san’s surname to her maiden name and somehow managed to register her as her grandmother’s adopted child.

By the way, all this information was heard while getting to know Isezaki-san and chatting around the hot pot at the Isezaki residence. It’s a mystery why she told me, just a salaryman living nearby, about such circumstances.

The problem lies in the six blank years when she was missing. According to her, she didn’t actually suffer from amnesia; she says that during those six years, she was transferred to this other world. She claims to have lived there as a Great Saintess. It’s truly like a story from an isekai light novel.

As we walked across the barren land while discussing such matters, we eventually saw a tall wall in the distance. The wall had some damage, and we could see people working to repair it from afar. Seeing this, Isezaki-san let out a relieved expression.

“It seems like we’re definitely near the frontline city of Grandain. Sir, your suit stands out. Please take it off now.”

I obediently removed my suit as instructed by Isezaki-san. However, the shirt I wore underneath was soaked in bl00d.

“Ugh… Wouldn’t this make me stand out even less?”

“No, because this is a battlefield… It should be fine.”

Saying so, Isezaki-san took off her school blazer, squatted down, grabbed some dirt, and started to dirty her pure white blouse with it.

Looking at the now slightly dirty blouse, Isezaki-san nodded in satisfaction.

“I think this will make us less conspicuous. Now then, shall we go?”

Putting our jackets into our respective bags, we proceeded toward the wall once again.

As we approached the wall, a shirtless man who had been working nearby called out to us.

“Hey, missy, are you a mage? It’s been a disaster today. And you there, are you okay covered in bl00d, bro?”

I had been called “sir” repeatedly, but for the first time in a while, I felt like he called me “bro.”

Even though it’s another world, it seems like language still works here. This is also a common trope in isekai light novels, but what’s the logic behind it…?

Unlike me, who was bewildered by my first experience in another world, Isezaki-san, who had already experienced it, shrugged nonchalantly and replied.

“That’s just splattered bl00d. But anyway, how much longer are they going to keep up this barren dispute? This year marks… how many years now?”

“Eighteen years. I’m really getting tired of it!”

The man laughed heartily. Isezaki-san also smiled wryly and said, “I know, right?” Then, she passed by the man, and I followed after her.

At that moment, Isezaki-san muttered under her breath.

“…Eighteen years means… this is the world ten years after I was killed.”

Isezaki-san frowned. Another ominous word came up again, but what could it mean?
