If you saw someone who was completely different than all other "humans", would you think they were the weird one, or is everyone else the weird ones? The conflicting though process of trying to figure out what is a "human", Shirasaki is just an average boy with some average friends when a weird girl Kamimura Yuuka pops up in his life. The summary is quite misleading although the boy does not really have any affections for her in the beginning it starts to grow but as far as the english scanlations are concerned he is definitely not in "love" with her yet. Nevertheless there is arefreshing light romance in this manga with a weird physiological twist.
All in all the art is very nice, and portrays the mood nicely, and the personalities are very well though out.
Anyone who is interested for a cool sci-fi or fantasy read with a touch of romance will probably like this and the story keeps on getting better
