Nazo no Konojo (Mysterious Girlfriend X) Speculation/Conspiracy theories

In one of the "Author's notes" sections, he talks about how the series came to be. The original idea was to have Urabe be a descendant of some type of mystical youkai or something, I believe related to either Discommunication or Yume Tsukai (which is related to Discommunication as well... the spin-off manga Discomunication - Spirit World is considered a prequel to Yume Tsukai.)

However, his editors staged what read as, basically, an intervention and told him that he needed to break out of his rut! He needed to stop writing manga that relied on youkai and overt supernatural elements and write something more "down to earth", so to speak. One of the editors commented that it wasn't necessary to have Urabe be some special person with special powers, because the most mysterious creature in the world to a teenage boy is none other than a teenage girl! She can be mysterious just by the very nature of the differences between boys and girls and the protagonist's lack of experience and knowledge of these rare, exquisite beings. Thus Urabe Mikoto, normal girl, was created. (Her breasts got larger as the series progressed though...)

Not that he may not pull an alien out of his hat in the long run...
