The 28 episodes i´ve seen on youtube were very enjoyable. Nice characters, a story that you are really drawn into and good battles. This is one of the few mecha animes that caught my attention and i wasn´t dissapointed after the first few episodes. The Problem is, that you can hardly find any episode after the 28th. There are just raw ones with a lenght of 9 minutes... But if you like Mecha animes this 28 episodes must be seen.
