i agree with u hyuuga. it went slow and downhill. i have a feeling that they are not going to make any second season or whatever season at all, though, imo, they rushed the ending. since the plot was beginning to lose the audience interests. but there are a lot of questions that are left unanswered, i think.
but in the bright side, its a good anime, id say. if they decided to make a continuation of this series. i will watch it.
