YandereDev said that he didn't think any rival's sibling will attend school, but Senpai's sister was an exception for logical reasons.

YandereDev stated that all rivals react the same way to murder: they run straight to Senpai. However, YandereDev has confirmed that there will be a teacher and nurse rival. Two grown women would not run to Senpai.

So reasoning that YandereDev said all isn't really going to help here. Other reasons would definitely work, though.
