Okay, this is another filler episode. But, everything is serious since the dragon showed up which also means there are no echii scenes as usual. Since Saito lost his sword from the previous episode (and is somewhat useless), complicated problems got between Saito, Louis, and the gang. There is also a surprising event for Saito near the end. Other than that, I don't have much to say besides the filler filling in more details on what the dragon and people are going to do. I'm somewhat satisfied but I can't wait for the action on the next episode. Overall, this is an interesting surprising filler.
Conclusion: Interesting surprising filler.
