At least I don't think of it as a filler! So that's a good start already since I haven't read or watched it yet. :D
Black Bullet is not bad! I would compare its action like Attack On Titan but to be honest I haven't seen that yet.
It's basically about a dystopian Tokyo in the future where there are these alien creatures called Gastrea that carry their virus that would cause people to transform into the monsters. Then there are these kids called "Cursed Children" who have a small percentage of the virus within them and are able to control it allowing them to have superhuman abilities so they a key advantage in fighting against the monsters. P.S. they have to be all female because of the virus or whatever so it's moe as helllll. LOL
also, the anime/manga is pretty new and the anime is caught up with the manga
Sorryyy sorry! It's been hard to keep up activity on PC lately.
I also heard they were going to make a Sinbad feature; is it going to be like a few episodes or a feature film/movie? o.o I'm okay with both I guess, but I generally am impatient though when it comes to anime episodes XD Especially new ones I'm starting like Black Bullet and No Game No Life.
