Which one was al?Maybe. I think we'll see Al, because he's like 3000 years old or something.
Iinchou-san should still be alive, it's true, given that she was around in the original future, if I recall correctly, at least.
I'm not really sure how time travel works in this universe. When Negi used that time watch/device with the power of the World Tree, the events of the original timeline appeared to be wiped out and Chao was okay with it. So, I would think that there is no sleeping Asuna, but she might still be around somewhere. I wonder if Konoka's father left Kyoto and became the headmaster, assuming that Gramps died after another 50 years.
I wonder if Negi's "death" in the original timeline was supposed to tell us that he sealed himself and took Asuna's place or something, unless she was sealed as well still (which Iinichou implied)...Although, now he appears to have sealed himself for some other purpose, as Asuna was rescued in the changed timeline.
From what I gather this is the sort of universe where every event creates an alternate timeline. Anyways, there should be an sleeping asuna because that was never undone. We simply saw asuna return back in time thanks to chao and eva. Events themselves don't get wiped out, they simply create a new timeline. Which is why chao had a device which allowed her to travel between timelines and in time.
Odds are the situations are similar. In other words what happened to negi was inevitable. Now, we know the situation was solved because the manga even went as far as saying that negi did succeed when asuna was still in the future. Even the tomb which asuna finds of negi seems to be similar to the one touta visited (although in a different location).
