On one side you have the peaceful humans and on the other side are the magic-using, war-hungry "Heavenly Beings". Friends trusting each other seems to be a recurring theme in the plot. It's not your standard fantasy story with demons and rescuing a maiden though! The story requires you to pay attention. Not all concepts were explained properly, but that was okay with me since it didn't stand in the way of fun.
I didn't really have any big issues with the story. One of the characters, Suzume, gets her own little side-story early on which I thought had no relevance to the main plot.
The only reason I can see why is because she would have had no depth at all otherwise.
You've probably seen by now that this is made by Kyoto Animation who also animated Suzumiya Haruhi, Clannad, K-On! and several other extremely popular shows. The animation may not be state of the art, but it's still pleasing to the eye and very colorful. I didn't notice any scenes where the characters looked awkward if there were any. Definitely be on the lookout for small little details you might have missed on your first time watching if you're watching it a second time like I did.
Not much to complain about here. The opening song is by Eufonius, best known for remixing Mag Mell for the first Clannad season. The ending song is by Ceui, who also made the ending song for the anime "sola". Personally, I liked both songs. The background music throughout the show helps set the mood and raise the tension where needed.
Yumemi, the main character, has great character development throughout the show. It's a nice change to see a girl character who isn't a total doormat for once. She is actually the one who saves the day instead of being saved every time. Her friends are there to support her which makes me like them and Yumemi more.
The other main character, Munto, who the series is named after also gets some good back-story and development. He starts out rather impatient but slowly learns to trust Yumemi. His back-story was understandable but it could've gotten more attention in my opinion.
The rest of the characters are not so developed but that's understandable due to the shortness of the series. One thing that bugs me is that they could've explained the motivation behind the main bad guy better.
I enjoyed this anime even more the second time I watched it. What I enjoyed the most is how I got sucked into the Munto universe for awhile (no pun intended). It's original fantasy fun.
This show is a mix of several genres like fantasy, romance, action and slice of life all put into a short nine episode show. If you like any of those then why not try it? I wish there were more episodes.
