The time goes back a bit.

'What's in store for where we're going?'
You know what? I don't know. That old shipyard from World War II?
'Oh yeah, that's it!　It looks kind of chickened out.

　The bus was bustling with activity. Each of them were sitting next to each other with their good friends, talking and playing with each other. When I look at it this way, it's not much different from the usual scene in Class 4 of the second grade. Although there was no one who shouted in a strange voice, the guide and the driver did not seem to be able to keep up with the high tension that was characteristic of boys and girls.

　The most exciting group was probably that of Ryuuzaki Kunihiro.
　He is a tall, handsome, good-lookin', athletic, picture-perfect honor student. He is popular with both men and women for his discriminating personality, and naturally, he is surrounded by high-end students. Naturally, an aristocratic group is formed, and other students gather around him.
　The girl's group is largely divided into two groups: the queen, Benii Asuka, and the group of Himemizu Rin, who is close to Ryuzaki. The latter is the one that seems to be having fun, but it's the former that has a more mature atmosphere.

　And the group Kyousuke belongs to has nothing to do with such things.

　Kyousuke Soraki, Akira Hino and Yoshiki Koganei.
　Kyousuke is hirsute and Koganei is chibi-gari. They're a group of otaku who don't have much of a deviation in appearance. The only one, Ei, is as handsome as Ryuzaki, but he hangs out with Kyousuke and his friends and is too brusque about his attitude towards the people around him, which is why very few girls come up to him.

'Utsurogi, look at this. That's the cruiser they were building at the shipyard we're going to!

　Shrinking quietly in a corner of the bus, Koganei holds out a page of a magazine to me with excitement.

　In contrast to the majority of the class who think shipyards are tally, Koganei's excitement is on the upswing. Kyousuke has had a bit of a taste for the military, so he understands the feeling. Plus, when it comes to battleships these days, they're pretty girls. Of course, both Kyousuke and Koganei are playing the social game that has the otaku world buzzing.
　Ei may have gotten bus sick, but he remained silent and refused to move.

'But me, when it comes to cruisers, Kawauchi-chan is the one I want.
"Utsuragi, Kawauchi was a light cruiser. They're building a heavy duty truck at the shipyard we're going to.
Oops, that's a rookie mistake.
"If it's a heavy cruiser, it's gotta be Atago!　Aoba or something like that would be nice!　I like the Takao type!　Atago and Takao!

　A few girls sitting nearby are looking at Koganei as if to say, "What the hell is this guy creepy? It's true that Koganei has an odd habit of shouting at his wife when he gets excited, but you don't have to look at him like that, Kyousuke thinks. I like what I like. Kyousuke just doesn't scream either, but he keeps his passion inside.

"Speaking of which, Utsurogi. She kinda looks a bit like Aoba in her vibe, doesn't she?
'What?　You mean the Princess Water?

　Koganei stares at Himemizu Rin, one of the aristocratic group frolicking at the front of the bus. Himemizu is one of the best sprinters in the track and field club, her entire body is toned and toned, and her sailor suit looks great even from a distance. Kyousuke has always thought that she's no stranger to the three most beautiful girls in her class, but...

Do they look alike?　It's slender, and the Himemizu looks like a destroyer, not a cruiser.
'Well, I don't know. I think we're alike.

　As he said that, Koganei's eyes were shining brightly as he looked at Himemizu Rin. Patting him on the shoulder, Kyousuke said, ''Don't do it, Koganei.

''Koganei, don't do that guy........''
What, what, why?　It wasn't, what are you talking about?
The world we live in is so different...

　Like Ryuzaki, Himemizu Rin is the type of person who treats everyone in her class without discrimination. She'll contact Kyousuke's group if she has something to do, and she speaks to them gently and cheerfully without any disdain or pity. It's unavoidable that Koganei would be moved by this.
　But after all, it's an unfulfilled love. Being able to treat all kinds of men kindly means she has that much choice. Kyousuke doesn't want to think that Himemizu Rin is a slut, as one fan, but at least he doesn't see any reason to go out of his way to choose Koganei.

''Yeah, don't........''

　Ei, who was leaning against the window, blurted out.

''Even Hino?''
Ei, you're awake, you don't look so good. Are you okay?

　Still pale and groggy, Ei didn't nod or shake his head.

　This guy has always had a weakness for vehicles. And yet, he doesn't tell others about it, which is why he always has a hard time at times like this. He told me that if he said he wasn't good with vehicles, he would be moved to the front seat and the front seat would be uncomfortable because the teachers and the group of people in the rear would be there. As a rule, they don't want to be spoken to. He had a good face, but he was a great communicator.

'Kyousuke, Koganei.... I'll tell you an interesting story. I remember from the cruiser....

　He was a guy who was worthy of being a friend, even though he was groggy, he was willing to change the subject.

"What's that? What's that, about Hino's wife?
I don't play social games......... As a matter of fact, there's a rumor about the shipyard I'm about to go to...

　According to Ei, who has been talking incessantly about it, there is a phantom heavy cruiser in the former Japanese Navy that was erased from existence after the war. The ship was built at the shipyard you are about to visit, and was deployed in a naval battle near the end of the war and then disappeared.

Wasn't she sunk?
I think so too, but... "I think so, too, but it's gone. And then the registration was deleted in an unnatural way.
Hmm, maybe he's tripping to another world.
What's that?

　When Kyousuke plunged in at Koganei's words, Chibigari Koganei said with a twinkle in his glasses.

'What's up, Utsurogi, do you want to read some internet novels or something?　There's a lot of that in commercial novels these days. It's about going to another world.
Oh, I know that...

　A schoolgirl comes out of the front seat with a look on her face.

　The plain, bespectacled girl is Sakuma, as I recall. She's shy and has a penchant for being overly pessimistic, and tends to be a bit of an outcast in her group of girls. As if to prove it, the one sitting next to her is also a delinquent girl who is an outcast in the class.
　Sakuma is a literature student. That said, whenever Kyousuke goes to the library after school, he often runs into her. We've talked about our favorite novels and children's literature a few times, but I didn't think he would bite me here.

'You know!　It's funny!　I mean, I've registered on a posting site and I've buzzed quite a few things, you know, like this and that!

　As I thought, Koganei shouted loudly, which surprised everyone around him, and showed the screen of his phone to Sakuma.

''Ah, yes. It's interesting......... I, like this or something........
Oh, the villainous reincarnations!　And I'm a girl!

　He probably didn't take offense to that statement, but it wasn't a good way to say it. However, since it was too much of a chiding, Kyousuke decided to just let Koganei speak. Sakuma didn't seem to expect to be talked about with so much tension, and with his gaze, he asked Kyousuke for help, but I sent him a mouthful of 'ganbare' for now.

　Looking at Ei, I close my eyes, thinking that I should go to bed too. Koganei was still annoying Sakuma with his machine gun talk.

　It wasn't long after that that the bus carrying the second year and fourth group of students had a fall-off.

Um, anyway, is that all of them?

　Ryuuzaki Kunihiro muttered to himself in front of his transformed classmate.

　It's a good thing that you can't get away from the fact that you can't get away from the fact that you're not going to be able to get away from the fact that you're not going to be able to get away from the fact that you're not going to be able to get away from the fact that you're not going to be able to get away from the fact that you're not going to be able to get away from the fact that you're not going to be able to get away from the fact that you're not going to be able to get away from the fact that you're not going to be able to get away from the fact that you're not going to be able to get away from the fact that you're not going to be able to get away from the fact that you're not going to be able to get away with it. Ryuujin, I guess you could call it that. The handsome man was ruined, but this was a different vector of coolness, and how very envious it was.
　All hell broke loose for now, and it was time to reassess the situation. It was Ryuzaki who came up with the idea. The mood of the class was set when Goubayashi, who was in the same upper caste as him and who had been transformed into a rather rugged demon (Oga), agreed with him.

　Kyousuke, who has become a skeletal human (skeleton), and Rin, who has become a sticky ghost (waterslime), are sitting in the corner for now.
　As for Kyousuke, he would have liked to sit with Ei and Koganei if he could, but it wasn't even clear which monster those two had turned into. Probably all the other classmates were too. I'm not sure who the monster next to me is, and I'm squirming.

For now, almost everyone's face has changed, so I'd like to check again. The first one is Ryuzaki. This guy is Goubayashi.

　Ouga nodded at the dragonman's introduction. We all know so far.

''Also, there are two other people who haven't changed........ Asuka and Inugami, right?

　Yes, Benii Asuka, the class queen, and Inugami Hibiki, the straggling delinquent girl, had hardly changed in their appearance. Even though they looked like humans, their facial structure had changed, Benii's eyes had only turned blood red, while Inugami had only grown dog ears and a tail.

　Vampires and werewolves, Kyousuke thought. If this change was anything to go by, the two of them were definitely bites. 'I envy you.

'Well, besides......... Then what's that fireball floating around there?''
"Akira Hino.

　Kyousuke was relieved when he suddenly heard a name he knew. If he looked, there was a red fireball (wisp) floating around in a swooshing motion. The handsome man is ruined. What a waste, really.

'Ei, over here, over here!　It's me, Kyousuke!
Oh, I knew it was you, Kyousuke. You're still skinny as ever.

　Ei, who had turned into a wisp, flew straight to Kyousuke's side. Ryuzaki was carefully taking notes, using the rock as a desk.

''The fireball, in the fire field........ Gaikotsu, Utsurogi........

　Scratching his forehead with the head of his pen, Ryuzaki continues.

'Then what about that slime there?　Koganei?
Oh, no. Ryuzaki-kun, I........

　The moment Rin uttered the words, Ryuzaki took down the pen in a ragged way.

''Rin!　Are you Rin?
Uh, yeah...

　Disappointment was heard from all over the class.

　That attitude is a bit awful, isn't it? And Kyousuke felt quietly indignant. Rin may have changed in appearance, but inside she was the energetic girl herself.
　Sure, Rin was one of the three most beautiful girls in the class, a blue fluffy slime now, but it didn't feel right to judge her based on her appearance alone and be disappointed. And moreover, to say it out loud. Seeing Rin shrug small, I think even more so.

''Um, Koganei, I........''

　Kyousuke turned his gaze as such a voice came from the corner. Immediately after, he was surprised.

　No one must have thought to check on Koganei's appearance. But a few seconds later, the bewilderment became a murmur and propagated throughout the class. Both Ryuzaki and Goubayashi were pouting. It was impossible to read the expressions on Slime and Wisp's faces, but probably both Rin and Ei must have been surprised.

　The flowing blonde hair and emerald green eyes. Long, pointy ears, and a long, sleek frame, and a sweet mask that far surpassed the pre-Tatsusaki's before the transformation.

　The man who called himself Koganei was a handsome elf who bore no resemblance to that scantily clad man in glasses.

"This, Koganei...?
'Yeah...'

　Koganei said, shrinking back somewhat embarrassed. This would be the complete opposite of what Rin meant.

　Ryuzaki looked like he was in some kind of bizarre shock and couldn't take notes. Goubayashi picked up a pen with his big arm and dexterously wrote 'Koganei: handsome' on the notepad. If they looked at it just a few hours ago, it was an incomprehensible note.

　After that, the confirmation of the names continued with surprise and shock. When the names of all the class members were confirmed, Ryuzaki breathed a sigh of relief.

　Class 2, Class 4, all of his classmates are there. It was hard to say they were safe, but they all had their names.
　But the names of the driver, the bus guide, and the teacher who was leading them were not there.

'What the hell is going on here...'

　Holding his head in his hands, Ryuzaki speaks for the entire class.

''It's a trip to another world...''

　Koganei muttered to himself. Until then, none of them would have listened to his words, but they all watched him.

We're in a different world. This is a different world than our own.

　A reality that everyone thought about vaguely, but tried not to face.

　Koganei's words cast a dark shadow over the second year and four classes.
