On this episode, Shinku and his allies fight against the demon invaders and look for their leader. Meanwhile, the kingdoms' armies are struggling.
Shinku and the other heroes using their crystal always amuses me for some reason since second season. Anyway. the action was great but I was slightly disappointed that this demon plot wasn't really major and ended in just one episode. Also it was cool to see Nanami use her crystal for the first time and look much older. Other than that, will there be more war games as usual? Overall, awesome action episode.
Conclusion: Awesome action episode.
