个人第一次上传本子，因为自己特别喜欢这种小众xp，而且没人搬运这位老师的作品。于是我决定自己先做吃这个螃蟹的人吧（笑XD)

Huh. Was expecting the clones to start hooking up with other guys, not one singular guy lol. I'm guessing they only multiply when they have sex with the boyfriend?

So around the early years of mankind a portal to the number world opened up and humanity gained the power of numbers. Eventually someone divided by 0, which allowed the divide by 0 demon to cross into the human world (demon girl tag needed) and she placed a Math Stigma curse on humanity. In extremely rare cases someone will be born with some sort of math symbol birthmark. When such a person has sex, an effect occurs based on their symbol. The main girl, Tokiko, has x for multiplication. Whenever she has sex, she multiplies(though really it's more like addition). Also, she's constantly horny. All of this is explained by an old friend of the couple who's into occult stuff. The guy decides not to go further than foreplay because he's worried about what might happen if she keeps increasing.

The occult person continues investigating. Apparently people who are discovered with Math Stigma are quietly taken by their respective governments. There's a database listing a man with approximately equal who causes anyone that has sex with him to change in appearance to look like him and a woman with maximum in set who has a 90% chance of getting pregnant when she has sex and whose kids will inherit the best parts of both her and the father. It turns out the scummy NTR guy, Shugo has union U, so anyone he has sex with gets added to the set of his belongings.

When the main couple first met the demon, she told them that neither she herself nor Tokiko could lift the curse. The main guy figured that meant she did know a way, so when Tokiko first multiplied without him having sex with her he assumed that the curse was getting worse and left to ask her for the method. The real reason Tokiko increased without having sex with the main guy was, of course, that she had sex with the scummy guy instead, so the curse hadn't actually changed. There's only one Tokiko now that hasn't yet fallen to the NTR guy(because the others warned her off of meeting him earlier; the constantly horny part of the curse and the guy's own U make him irresistible to her). On the guy's end, the /0 demon is trying to NTR him from the girlfriend, and as far as he knows all of the Tokikos have been taken by Shugo, but he's still thinking of trying to get rid of the curse.

In the last few pages, Shugo realizes there's at least one Tokiko he hasn't got yet when pondering how he only likes girls when he's taking them from someone else. Meanwhile the occult girl Mary visits her aunt(or possibly just an older woman she knows; Japanese is kind of weird about using relative terms for unrelated people) who's also a demon to ask about the curse. However, the answer she gets is that curses come from jealousy, so demons who can get anything they want are never jealous and cannot curse anything. TBC
