Story arcs that could take place. (IMO)
Kaede promised to train Kotaru
Something about Zazie, who to me seems like some kind of spirit summoner or shaman
Alberio has involvement somewhere, but I have this weird feeling that once the festival is over, he wont be able to continue his contact. It said something to that effect in an earlier chapter.
How are they going to explain away Class rep or Makie's trip into the computer world with Chisame?
How are Chao's conspiritors going to be treated? They threatened Chao herself with a memory wipe so what will they do with Hakase, and the others.
And we certainly have more to learn about Asuna's past... Chapter 12 just came out in England and they refer to her as the "little princess"... How will this be explained.
Plenty of stuff to be getting on with, and that is without the introduction of the white haired kid again, who seems to have just vanished completly.
