You all are expecting too much of a 10-chapter manga, as good as it is, but there is some very nice mutual jealousy indeed. But it's definitely more SF than yuri, reminded me a lot of Atom The Beginning.
Neat, so we really are getting a proper sci fi story? That's cool.
I'm a bit surprised that a real science fiction story is getting uploaded here on Dynasty. They don't seem to like those sorts of stories as much here and they are quite rare.
I tried to suggest they upload Yokohama Kaidashi Kikō to this site, but it was apparently a no go. Yokohama Kaidashi Kikō is a lot like Girl's Last Tour in tone and setting. It's an end of the world science fiction, slice of life, iyashikei story with some yuri spice to help flavor the mix. It's a beautiful, award winning manga, but I guess it didn't meet the standards of what the admins are looking for.
I'm always happy to see more manga uploaded here that aren't just yuri romances, but rather stories from other genre where yuri elements are still present but the story doesn't necessarily revolve around it entirely. I would love to see more science fiction and fantasy stuff like this or Qualia the Purple.
