Thanks both Rurik & kagoto3 that makes things more clear...and i forgot about the name Vaizards
I read the manga for a big part so i know what's going to happen but was a little confused....and now since the anime continues....i completly stopped reading the manga
So you basically have...3 types..
Shinigami (different class of shinigami) [good guys] {human look alike, except cpt. Komumaru}
Vaizards (both hollows/shinigami) [neutral] {no hole}
Hollows (which are divided into categories) [bad guys] {hole}
