To be honest, this show was a complete nonsense. The Characters and Grey Ghost's Back Story were the only thing that made me watch it till the end. Story was totally underwhelming and there were way too many characters to remember.Climax was boring with no fight between 'Kaga' & 'Grey Ghost' and even in end they didn't provide closure to a lot of things.Animation was good from the beginning but they still took 3 Months break to broadcast the last two episodes with no changes in anything. My opinion; Don't watch this show.
Let's see the positive side of this anime, the animation was good as well as the sound mixing and sound edition, with a better plot could've been great but honestly was crap... Not a waste of time at least for me cause I'd loved the characters but i will definitely not recommend this one to anyone.
I rarely saw something that ridiculous ;-)
