The tenth rival will not be a yandere, which lowers the chances of there being yandere rival at all. Also, check the rivals page. I think that since the rivals will never know that they have competition for Senpai, then they probably aren't yanderes since a yandere would notice that Yandere-chan changes things around Senpai. You can also matchmake the rivals. What kind of yandere falls for another man?

Your theory is cool, but she might not be a rival. If [http://Yandere-chan is this impressive because when a yandere has someone to protect, they become capable of almost anything. Yandere-chan can kill almost any NPC she sees], then how tough would killing another yandere be? There will be no other persona that will kill you to try to stay safe. That also lowers the chances of a yandere at school, since a yandere would want to see tomorrow for her crush.

The other yandere could be Info-chan if she is the daughter. It's the most logical explanation. You will never see her at school, so that explains the part about killing her, a bit. But her persona is Evil! If you were to kill her, shouldn't she be able to kill you too since she is a yandere? Or at least fight back like a Hero, but to stay alive for her crush and not for the right reasons? Info-chan's persona, or any yanderes, would probably be something like loyal. That's what yanderes are known for, after all. I know the Dev possibly only meant that Yandere-chan and the mother had this persona, but it would make sense for another yandere to have the same thing!

Also, I don't think that a minor character who isn't a rival nor Info-chan would have such a big secret. The Dev said that all the rivals and no NPCs will have dark secrets. He probably wasn't thinking about Info-chan or The Journalist at that time, though. He has forgotten before, after all. Also, think about how The Journalist, Info-chan, and Ryoba Aishi, people with dark secrets all won't appear in normal gameplay, save for endings probably. That greatly lowers the chances of there being a yandere at school! Info-chan is in her own little club exempt from school rules, which might explain why she attends school but you'll never see her.
