Didn't see any reference about the limit of the skill one can actually take and no explanation of what actually completing the skill means or maybe there will be later....
yeah, that one thing is bad adaptation, its just like that the PvP thing in Aincrad can be interrupted by a third party before the battle finished
well now we can see a laughing coffin member seeing the battle there lol
finally some battle scenes with Yuki Kajiura music style in it, hope that it will be greater when the boss fight begin
next episode will be finished by fighting the boss I guess...
