It's stated (at least in the anime) in DC I that Sakura's grandma is the one that planted the magical tree in Japan. Basically what we have is a paradox happening with Sakura, the tree, and Rikka being her grandmother?

Spoiler:

Indeed (you'll need to keep reading, though)

Spoiler for question about Himeno. WARNING: Hints at Rikka end:

So since Kiyotaka and Rikka seem to be canon, does that mean Himeno married someone with the surname Asakura? It would explain why Sakura and Junichi are so close since their grandparents are related. And it would also explain why Nemu, Otome, and Yume look so simular to Himeno.

Spoiler:

What I got is that Himeno's descendant married with Jun'ichi/Nemu's child; Himeno is clearly Otome/Yume relative but appearances nonetheless doesn't seem to be of Nemu (or, well, she may be, but nothing in the scenario hints to that).
Also, Sakura and Jun'ichi's grandparents are not related, they are the same; it was stated in the original they were cousins.
