Let's not overlook and assume that senpai is 'supernatural'. For instance, yandev has stated senpai's backstory will be incomplete and that he had done nothing that info-chan claims as dark secret, so even if he had a dark secret of being supernatural, it will be completely irrelevant to the game. Oka's fascination to senpai is how she quickly fell in love with senpai. It's not unusual for people to become quickly attracted to someone. Oka believes he is supernatural because of how quickly she fell in love with him-not because he is supernatural. The same goes for the Basu sisters. Oka believes they are supernatrual, but until it is confirmed with yandev, they are not.
