non-humans living in modern times

"I screwed up aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"

　There was a boy running up a slope dyed in the twilight.

　His name is (Sakiba Sui) a boy in his second year of high school. He is now running backwards on the way home that he once took. A student on his way home from school stares at him wonderingly, but he also had a reason.

"Why did you forget the reference questions for the quiz?

　I forgot the paper with the reference questions for the quiz that will be held tomorrow. Unlike regular tests, it doesn't affect your grades that much, but if you score low on that quiz, your teacher will scold you. He didn't like it, so he went back to school.

"Haa...haa...ahhhhh"

　The season is the end of June, and summer is approaching soon, and it's time to get hot. It's only natural to break a sweat if you run at full speed in such a situation. He rolled up the sleeves of his shirt and headed for the classroom while enduring the discomfort of the sweat sticking to his skin.

"Yeah? What's wrong, Sakiba?"

"Ah, Sensei..."

　Since there are only students who are already doing club activities, it must have been rare to see the go-home club at this hour. Sui explained the situation to the homeroom teacher who stared at him with wide eyes.

"Haha, I see. Certainly, that teacher has a lot of nagging, so it's correct. Collect it quickly and go home."

"Yes"

　The homeroom teacher walked away waving his hand.

　Seeing him off, Sui also rushes to the classroom. While the voices of the baseball and soccer clubs are faintly audible, Sui does not pass anyone until he heads to the classroom.

"Well, of course there's no one here."

　Yes, he thought there was no one.

　However, when I approached the classroom, I felt something like a slight presence. Wondering if someone was there, she quietly peered into the classroom, where she saw a beautiful girl in uniform looking out at the scenery.

"... Koshimizu?"

　The only person left in the classroom was Koshimizu Sakia, was a girl who transferred to school in April. Her silky silvery hair, overly well-groomed features, and burning bright red eyes are impressive, but above all, she has a style that is far from being a high school student.

"... you're still beautiful"

　Averting his gaze from the huge bulge on his chest, he looked at her again and muttered so. Precisely because she is such a beautiful girl, Sakia has been the center of attention from her first day at school. It's been almost three months since she came to this school, but according to her friends, the number of times she's been confessed to has already reached double digits.

"... well, it's not the time to be fascinated."

　A beautiful figure and a style that stirs the desire of men, how many boys in this school would want to make her a thing. She's about her age, so it's only natural that she'd want to be close to a beautiful girl like her. However, compared to her, Sui is too ordinary. Precisely because he understands that, from the very beginning Sui has no faint expectations of her.

"..."

　I put my hand on the door, but for some reason I feel reluctance to go inside. No, there was more tension than resistance. It's not that she hasn't talked to her about her, yet she's so beautiful that she hesitates.

"... Alright!"

　Excited, he opened the door and went inside. However, at that moment he saw something impossible.

"I'm already tired, day after day... oh no!"

　Wings appeared on her back when she suddenly raised her voice, and a single tail appeared from inside her skirt.

"...yes?"

"Eh... What!?"

　Saki was suddenly speechless, and Sakia was greatly surprised when he noticed him.

(... Huh, wings and tail? Accessory or something... But the wings are flapping and the tail is undulating.)

　The wings and tail were moving as if to express Sakia's confusion. I thought she was an accessory or something, or some kind of cosplay, but I don't think so.

"..."

"..."

　Sui and Sakia staring at each other... Sui was the first to move.

"I forgot the reference sheet for tomorrow's quiz... erm~"

　Apparently, he decided to stay with the body that didn't see anything. He doesn't look at Sakia at all and goes to his desk, but perhaps it's a prank of God, her seat is in front of Sakia's... In other words, she approaches her own seat. That means I will pass by her.

"Ah, there it was~"

"..."

　It's a sticky reading that's easy to understand.

　Sui thought that he had seen something he shouldn't have seen. If this wing and tail were real, it would be the greatest discovery of the century. However, humans with wings and tails do not exist in this world where Sui lives... because such fantasy does not exist in this world.

"Okay, let's go home."

　The object was recovered.

　I told myself that I didn't see anything, and he tried to leave, but he put a hand on my shoulder.

"Wait"

"..."

　The hand placed on her shoulder was definitely Sakia's. She is so powerful that I wonder where such power comes from, and she does not flinch at all. She stood in front of the water with the sound of small footsteps.

"Did you see my wings and tail?"

"...that"

"Did you see it?"

"yes!"

　Sui nodded while being terrified at his bright crimson eyes.

　At that moment, Sui intuitively realized that she was definitely not a person. I'm sure she still can't believe it, but she can actually see her wings and tail on her back even now.

"...Haa. Well, it's my fault for letting my guard down. In that sense, there's nothing wrong with Sakiba-kun. Yeah, I'm the one who's at fault."

"..."

　Even though he says it's his own fault, he has a sharp gaze when he looks at us. Perhaps he was going to be killed?

"Look into my eyes"

"...a"

　Look at her eyes, I looked into her eyes.

　Then, an indescribable sensation like a numbness in my brain enveloped me. At the same time, it seems that it even smells sweet, and I feel much better. It wasn't that he was dazed, but he was staring at Sakia with a blank head.

"Forget what you just saw, you didn't see anything, okay?"

"... I understand... I knew it."

　Because he was in a dreamy mood, Sui ended up muttering.

"You're beautiful... Koshimizu-san."

　Of course, Sui does not correct it. It's just that my brain isn't working. However, Sakia took a step back at her words just now.

"Are you suddenly saying Nyan!?"

　Sakia's face turned red, but she immediately took a deep breath to calm herself down. She continued her words, biting her fingernails, still a little red in the face.

"I've been hiding it until now, but it would be terrible if the succubus came out. Mother would get angry, and if it spreads, I'd have to run away again ... Well, I'll make you forget what you saw just now. It's perfect!"

　Sakia muttered to that extent and clapped her hands.

　As if waking up from sleep, Sui came to his senses and looked at Sakia in front of him.

"Hello Sakiba-kun, what's wrong?"

"... no... that"

　Sakia put her hand to her mouth and smiled, then turned her back on him. Just like that, she grabs her bag and turns around towards the exit of the classroom.

"It's fine to be asleep, but don't spend the night at school, okay? See you tomorrow."

"Ah..."

　Seeing off Sakia who left the classroom, Suizi muttered.

"... I remember everything."

　Yes, Sui remembered everything.

　All the words I heard from her are firmly engraved in my memory.

"... a succubus"

　Said she was a succubus.

　A race called a succubus that appears in numerous manga, games, and anime, but... well, it's an obscene story, and most of the works depict it as a naughty monster.

"No, no way... but"

　As expected, I can't believe it, but if that's the case, how should I explain those tails and wings? How should I explain that feeling that my eyes were shining and it was as if I had been hinted at? There were many questions, but more than that, she was worried about her words that she would have to run away.

"... I don't know... I don't know, but Koshimizu seemed to be in pain."

　I can't forget Sakia, who seemed to endure something... There were many things that bothered me, but Sui decided to keep them to the bottom of my heart. She said that what she saw today was a dream, so she decided not to care.

　However, in a way, this encounter was the beginning of a tumultuous life for him.
