Kashiwa Higashi High School. Located in Kashiwa, a city of Chiba Prefecture, it is considered an impressive public school.

Between highly-favored teachers, excellent graduates and the reputation as an unblemished institution from any scandal... it was the best place to set up her own fief. Kondo Kumiko was not the finest teacher, but she was praised as a kind and understanding educator with an impressive curriculum to flaunt whenever necessary.

Of course, that last bit wasn't necessary. Not when her studies at Tokyo-U had made her aware of many things about life: you don't need to be too strict in class with students to get the point across and... young men can be so easy to play with.

Despite the wonderful smiles she so offered to anyone looking, Kondo-sensei had a habit to 'claim favorites' in her class. Students that, somehow, would get high marks and be offered potential scholarships depending on their age and year of study.

She made no distinction between boys or girls, knowing that trying to 'prey' on just a single group would have raised suspicions on her preferences. And while for a month this had gone undisturbed, she had just a feeling that something was up when she was asked by a fellow teacher to go to the principal as she had asked for her after school.

Ah yes, the principal. Out of all impressive entities at school, Kumiko genuinely feared the principal of the school. Takeda Shunichi was what many ladies would call an 'enticing piece of meat', but also a wonderful man that truly cared for his students.

In his 30s, the black-haired man with piercing yellow eyes had the frame of a muscular athlete. Kumiko was sure he hadn't been part of any professional team, which made those broad shoulders of his proof that he was a diligent man even during his free time out of school when it came to exercising.

Still, the bespectacled man was not a goof or a naive teacher. He had given her a strange look from the get-go as they shook hands. It was so frightening that she had delayed her plan by a week to make sure that she was extra covered in case someone tracked her efforts down. And she was sure that, despite the growing guttural feeling that she may be up to some bad news, her ass should be insured from any major issues.

That was what Kumiko thought and hoped... until she took a seat by his office. His desk was neatly-ordered, the paperwork already compiled and dealt with. Documentation still lingered around, but the man had already completed his chores for the day and... he was giving Kumiko the flattest look a normal human should be able to accomplish.

Yet, it wasn't his staring that was responsible for her unease. It was a student she had personally avoided due to her true nature. And that was currently staring at her with the most inhuman look possible.

If Takeda Shunichi was the pinnacle of human strictness, then the girl known as Saeki Chizuru, the Head of the School Moral Committee, was the fine opposite of that and, despite that, they were known to be a 'double threat' for anyone trying to cause grievances to the school with bad behavior.

There were many rumors that surrounded Saeki'-chan', ranging from the fact that she was a notorious slut outside of school to the fact she was actually a demon girl due to her few 'unusual details' when compared to regular humans.

While there was nothing odd about her skin or hair color, there were some 'odd details' like her hair having two horn-like sections sprouting from the side and appearing like genuine demonic horns. And some of her lower bangs, among those that reached her pert butt, looked as if it was a succubus tail.

The most incriminating trait was the girl's eyes. Chizuru has pink eyes... with hearts throbbing in the middle of those. Some said she was wearing special effect contacts, but Kumiko was familiar with that sort of things and she knew one wouldn't go around wearing those all the time.

"Kondo Kumiko-san, I am glad you could make it. I will not take too much of your time, but I have asked for you to discuss some grave accusations levied against you and what the school intends to do about those."

This was the end of the beginning, her 'endsieg', but the woman still held her head high.

"W-What about, Takeda-kouchou?"

The man shifted papers, then cleared his throat and delivered the harsh news. "It has come to my attention that you have engaged in improper actions with some of those students you praised and promoted above others. An investigation was thus launched at the behest of Saeki-san and other members of the School Moral Committee and, after some careful efforts to study the situation, it has been confirmed that you have indeed done such a thing with more than a dozen of students."

"T-That's ridiculous! It's slander. I-I will have my lawyer-"

"Work on handling your pending criminal infringment case since the parents of the students you have violated have all accepted to see you incriminated for this shameless situation."

Her words died in her throat. Kumiko had know it could have been deadly for her if she had gone that far, but to claim so many pure boys and girls- it was too difficult to hold back and... her thoughts perished as she heard a brief giggle. She looked at Chizuru, the smile now twisted in a most devious one.

The monstrous girl had clearly been looking forward for this moment, but at the very least she could do something to delay the inevitable.

"I-I suppose I have a week to-"

"No."

Her eyes narrowed at the principal. "Takeda-kouchou, it is by contract that I have a right to-"

"The contract, Kondo-san, says that these privileges are to be forfeited upon the possibility of criminal investigation. There's also the fact that if you are trying to clear some evidence that it is no longer feasible as the police has already found your playroom."

This was where the tears started to flow. The 'play room', the small unused storage room she had reorganized as a little sex dungeon for her and her pretties- it had been found. She was finished. Her gaze lowered to the desk and she felt numb.

"Which is why I asked you here to tell you that you are fired, you will not be paid any retribution, and your name shall be struck down from any major documentation this school has you part of. Also, we will start looking into other potential issues you have caused and we will press charges if it is truly necessary," The principal then stood up and glared at her from his towering posture. "You are dismissed."

Kumiko left... and her plans, together with her life, were thus destroyed.

"That was harsh."

I hummed as I took to seat again once Kondo had left my sight. I had already known she would be trouble, but I knew that rushing accusations would have been too dangerous. Luckily for me, I have someone reliable to help me investigating.

So, I looked at Chizuru as her smug grin had hardly waned after the depraved student-predator had left our sight. Saeki Chizuru was indeed a 'Noble Succubus'. During my first year as the 'isekai principal' of this peculiar school, she had been summoned by some dumb girls that had been promptly put through several months of detention as they were trying to 'become higher demonesses' by summoning Chizuru.

Of course, they were caught playing with the chalk and were put through detention once I was done talking with Chizuru. Succubus or not, the girl was just minding her business when she got yanked in the real world and, while many would just ask to be brought back, the Succubus asked for something I was more than happy to provide after speaking with her parents.

"Oh, can I study here too?"

Turns out that some bits of Hell didn't have mandatory education, so Chizuru was a bit illiterate despite her parents' high standing. After I was done telling them that the most they had to pay were the books and have her wear the school's uniform, they were convinced to have her around since 'it meant less trouble for them'.

Curious, but I hardly had any trouble with Chizuru. Beyond the fact she was a notorious prostitute beyond the school's walls. As much as this would be horrendous for a human girl to do, I had been able to get a book about her kind from the girl herself and... it was better this way.

She was quite reserved at school, hardly causing any woes during school hours, and tended to be praised as a well-mannered student and president for the Moral Committee. It was ironic how exemplary of a student a succubus could be but... she also had a bit of a 'kink' in punishing people. Especially those 'deserving' it.

"It was needed."

"I would never say otherwise, Takeda-kouchou," She hummed quietly, then glanced at her phone. "And I think I can take my leave, yes?"

I sighed and nodded, "You may, Chizuru."

Beaming, the girl was soon off to... do stuff. I wasn't her parent or guardian, but she mentioned that she could handle herself just fine. So, it was me going out for another patrol as usual and handle-

CRASH!

I facepalmed hard as this was the third time this month that I got this scene happening. Same scenario, same people, same detentionable student.

"G-Gh, you monster, I will... o-oh, Takeda-kouchou."

Black hair pulled in twin tails, amber eyes, a white 'combat dress', and... a very panicked look on her face.

Today was not Shinsato Yuri's day. Again.

"Shinsato-san. I see that you are feeling the punishment you're still supposed to handle is still too short. Let's add a month to-"

"SILENCE HUMAN!" A raspy voice exclaimed, and I turned to see the one that flung the girl into my office. A buggy fellow, classic magical girl's low-life foe. "ONCE I AM DONE WITH THIS LITTLE BRAT, I WILL-"

I rolled my eyes, I retrieved the one trusty tool that had aided me from the very beginning and-

"YEET!"

I hurled the piece of chalk at the bug's head. In just a moment, the light projectile struck the monster's head and vaporized it. In a normal 'restrained' moment, the attack would just struck the student and drag their attention. But that thing was not a student, and it was pissing me off over the fact these morons were targeting this office of all places.

...

"That was so cool~!" Yuri exclaimed. "Kouchou-sensei is awesome-"

"You're still getting a month for this. Same for you, Sawada-san."

I saw a silver-haired and blue-eyed head perking from the hole with a nervous look. Usually a dark-haired and dark-eyed bespectacled shy girl, Sawada Tamaki was quick to nod at the detention. Mostly so because she 'did not want to leave her best friend alone for this mess'.

"Next time, girls, drag the monster out of school."

"Hai, Kouchou-sensei."

My name is Takeda Shunichi, I am an isekaid Principal, and I am in charge of a wacky school in a wacky world. That's all I will say... for now.

So, important talk: This is an original story which will see a lot of xovering regarding school settings. Kashiwa Higashi High School is still the main location, the Principal/OC-I is still the main character, and while several names will be mentioned, only a few will stick around: Chizuru for sure is going to be a fixed presence in the story.
