well i guess if you are to ask akamatsu-sensei about anything in the manga, it's about some people like the relation of gravemaster and asuna. or about the royal bloodline of negi and its corresponding powers.maybe also the importance of fate in negi-kun's plan. something like that.^^

jmangeo,i suggest you trust akamatsu-sensei. i believe he wont' let us fans down and he will come explaining everything,in the manga of course. that's the beauty of his work.^^
