Deci said:Call me shortsighted but I think we have at least 2 more arc's left in the story.
In my mind, the story has just started, how can you even begin to think of the end at this point.
Like I said, it all depends on the arc's length. What if Fantasia goes on for 15+ volumes? Of course it could also be short, which is why the hypothetical number of arcs left is not very significant in regard to the number of volumes left.
