Kiyotaka Ishimaru

1) The person who's name is written in this book will be made to have sex.

2) The notebook will not take effect if the user does not envision the person they have in mind as they write the name. This way, others sharing the same name will be unaffected.

3) The person whose name is written down can be given a sexual partner by writing another name down within thirty seconds of writing the target's name. If no other names are filled in, the target will simply seek sex with the notebook's owner.

4) The details of the sexual escapade can be written within 5 minutes of writing the name. The named person will then be compelled to perform whatever acts are written in the book, for whatever specified length of time.

5) If a person's name is written in two Sex Notes, the one that was written first will take precedence if the acts contradict each other in any way.

6) Physical changes can be made to a person by writing their names in the Note followed by the desired changes. The restrictions are that these must be attractive to the writer, and they must be biologically possible.

"This can't be real. This has to be some sort of mean prank!" Kiyotaka Ishimaru exclaimed, as he looked around the courtyard in front of Hope's Peak Academy. Still empty. Still a few hours before campus actually opened. Most of his colleagues from Class 78, and the other Ultimates from Class 77 and Class 79 were likely still at their dorms, but he'd always come in early to ensure that everything was prepared (and then, regardless of if they'd asked for it or not, he'd show up to try and wake any late-sleepers.)

But somehow, he'd found this book resting atop a bench near one of the trees with no one around. The groundskeepers hadn't even come by yet, and no one had jumped out to mock Kiyotaka for looking over what looked like an empty notebook. This had to be a prank, of course. Books couldn't control someone into having sex, after all.

.

Could they? To one of his smarter classmates like the Ultimate Detective, such a thing would be impossible on paper, but to more "supernaturally" minded classmates, it'd be possible. Regardless, the book had either been left here as a cruel prank towards his more dirty minded classmates, or it had...

Kiyotaka picked it up and held it over his head. "I'LL BE CONFISCATING THIS BOOK! SHOULD ANYONE WANT IT RETURNED, THEY ARE FREE TO APPROACH ME AND ASK FOR IT! IF NO ONE CLAIMS IT, I WILL MARK THIS BOOK FOR INCINERATION!"

No one replied except the wind, even as he strode forth and marched towards the front of the building. No one at all. Perhaps the book was simply left here, and there was no issue with it. But, if it was actually magical- well, that'd be nonsensical. Wouldn't it?

Maybe just one test. One test of it, to clear the superstition within his mind. If nothing happened (which it wouldn't), then he'd just toss the book in the trash chute. Simple. Easy. And if something did happen, then he'd just be able to easily resist the temptation of the book and secure it, preventing worse from happening.

He pocketed the book. "What am I saying?" He thought to himself. "I've got to get to class!"
