The Case of Being Loved Excessively After Discovering the Beautiful Transfer Student was a Succubus

Chapter 1 – A Non-Human Living in the Modern Era

“Damn, I screwed up!!!”

There was a boy running up the hill at dusk.

With slightly quirky black hair and a kind face, his name was Sakuba Sui, a boy in his second year of high school. He was now going backwards on the road home he once took. The students on their way home from school looked at him curiously, but he had his reasons.

“Why did you forget the reference questions for the quiz, you b*****d!!!”

He forgot the paper with the reference questions for the quiz to be held tomorrow. Unlike a regular test, it wouldn’t affect his grade that much, but if he were to get a low mark in the quiz, he would get a complaint from the teacher. He hated it, so this is why he returned to school.

“Haa… Haa… I feel like dying.”

It was the end of June, summer was approaching and it was getting hot. It was natural to sweat when running as fast as you can in such conditions. Sui rolled up the sleeves of his cutter shirt and headed for class, enduring the uncomfortable sensation of the shirt sticking to his skin from the sweat.

“Hmm? What’s going on, Sakuba?”

“Ah, sensei…”

It was probably unusual to see Sui, who had gone home, at this time of the day, seeing as there were only students left who were involved in club activities. Sui explained the situation to his homeroom teacher, who rolled her eyes at her.

“Haha, I see. You’re right, that teacher does talk a lot. Now collect your things and go home.”

“Yes!”

With a flutter and a wave, his homeroom teacher walked away.

He saw her off and rushed to his classroom. He could faintly hear the baseball and football teams in action, but he didn’t pass anyone on his way to class.

“Well, of course there’s no one here.”

Yes, he thought there was no one there.

But as he approached the classroom, he felt a slight presence. He looked into the classroom and saw a beautiful girl in a school uniform looking out at the scenery.

“…Koshimizu-san?”

The only one left in the classroom was Koshimizu Sakia, a girl who had transferred to the school in April. She had silky silver hair, an overly-toned face and fiery red eyes, but above all, she had a style that was far beyond that of a high school student.

“…She’s still as beautiful as ever.”

Taking his gaze away from the huge bulge rising from her chest, Sui looked at her again and muttered to himself. Because she was such a beautiful girl, Sakia had been the center of attention since her first day at school. It had been almost three months since she came to this school, and her friends say that the number of times she had been confessed to had already reached double digits.

“…Eh, this is no time to be fawning.”

With her beautiful looks and style that stirred up male desire, how many boys at this school would want to have her for themselves? Sui was old enough to want to get close to a beautiful girl like her. But compared to her, Sui was too ordinary. Because he understood this, from the very beginning Sui did not have faint hopes for her.

“……”

He put his hand on the door, but for some reason he felt resistant going in. No, it was more nervousness than resistance. It’s not that he had never spoken to her before, but she was just too beautiful for him to take a second look.

“…Okay!”

With great determination, he opened the door and went inside. But at that moment he saw something impossible.

“I’m so tired of this… Every single day… Oh my god!”

Suddenly she screamed, wings appeared on her back and a tail emerged from her skirt.

“…What?”

“Eh–What!?”

Sui was at a loss for words at the sudden realization, and Sakia was surprised to see him.

…What, wings and a tail? Maybe they are accessories or something… But the wings are flapping and the tail is wagging.

Her wings and tail were moving as if to express her dismay. He thought they might have been accessories, or some kind of cosplay, but that was no longer the case.

“……”

“……”

Sui and Sakia looked at each other… The first to make a move was Sui.

“I forgot the reference paper for tomorrow’s quiz… Umm…”

Apparently, Sui had decided to pretend that he saw nothing. He went to his desk without looking at Sakia at all, but God forbid, his seat was in front of Sakia’s… In other words, approaching his seat means walking right by her.

“A-Ah, here it is!”

“……”

It was a clear barbed statement.

He thought that he had seen something he should not have seen. If those wings and tail were real, it would be the discovery of the century. However, in the world in which Sui lived, there were no humans with wings and tails because…such fantasies did not exist in this world.

“All right, time to go home.”

The intended item had been recovered.

Telling himself he didn’t see anything, Sui was about to walk away when a hand was placed firmly on his shoulder.

“Wait.”

“……”

The hand on his shoulder was definitely Sakia’s. It was so strong that he wondered where the power came from.

“Did you see them? My wings and tail.”

“…Um…”

“You saw it, didn’t you?”

“Yes!”

Sui nodded his head in horror at the glowing crimson eyes.

At that moment, Sui knew in his gut that she was definitely something other than human. It was true that he still couldn’t quite believe it, but even now he could see the wings and tail on her back.

“…Hah~. Well, it was my fault for letting my guard down. In that sense, Sakuba-kun didn’t do anything wrong. Yes, the fault is mine.”

“……”

For someone who said she was sorry, her gaze was very sharp. Sui imagined that he was going to be killed or something, but apparently not.

“Look into my eyes.”

“…Ah…”

He was told that, so he looked into her eyes.

Then, he was enveloped in an indescribable sensation that made his brain go numb. At the same time, he could even smell a sweet fragrance, which made him feel very good. Sui stared at Sakia with a fuzzy, if not dazed, head.

“Forget what you just saw, you didn’t see anything, okay?”

“…I understand… It really is…”

Because he was in a dreamy mood, Sui couldn’t help muttering.

“…Beautiful… Koshimizu-san.”

Of course, Sui didn’t correct them. That’s because he was not thinking straight. But with those words, Sakia took a step back.

“W-What are you talking about all of a sudden!”

Sakia’s face turned red, but she quickly took a deep breath to calm herself down. Her face was still a little red, but she continued to speak while biting her fingernail.

“I’ve been trying to hide it all this time, but if anyone finds out I’m a succubus, I’ll be in big trouble. Mother would be furious, and if it spreads, I’ll have to run away again. …Well, I’ve made you forget what you’ve just seen, so everything’s perfect!”

Sakia mumbled and clapped her hands.

Sui came to himself as if waking up from a sleep and saw Sakia in front of him.

“Hello Sakuba-kun, what’s going on?”

“…No… Um…”

Sakia smiled with her hand over her mouth and turned her back to Sui. She turned around and headed for the classroom exit with her bag in her hand.

“It’s fine to sleep around, but don’t spend the night at school, okay? See you tomorrow then.”

“Ah, yeah…”

Sui muttered in a whisper as he saw Sakia leave the classroom.

“…Somehow, I remember everything.”

Yes, Sui remembered everything.

Everything she told him was firmly etched in his memory.

“…A succubus.”

She said she was a succubus.

Succubus, a species that appears in numerous manga, games and anime… Well, to be fair, most of them depict them as naughty demons.

“No, no, no, no way… But…”

He didn’t believe it, but if that’s the case, how could he explain the tail and the wings? How could he explain the glowing eyes and the feeling of being under a spell? There were many questions, but he was more concerned about the words she said in a strained voice, that she would have to run away again.

“…I don’t get it… I don’t get anything, but it seems that Koshimizu-san went through a rough time.”

He couldn’t forget the way Sakia looked as if she was enduring something… Although there were still many things on his mind, Sui decided to put them away deep in his heart. What he saw today was a dream, so he decided not to worry about it.

But this encounter was, in a way, the beginning of his noisy days.
