This seemed unbearably short even for most anime. Overall the whole anime is well done other than the issues that arise with its length.
The way the episodes are divided up is very well done. They can draw you in, keep you intrigued and then end on a very good note. Like an shooter hitting their mark every time. The characters all get introduced unbelievably well. Really this anime could be the standard for introducing characters! Its always so smooth even for big reveals, I have never seen it done so smooth. The design of the anime is pretty standard but I don't consider that a bad thing. They even kept the eyes mostly one solid color which is nice keeping with traditional modern anime.
My one issue is the length. If there isn't a season 2 then this anime is definitely a 5/10. If this is only the first I would definitely rate it no less than a 7/10. Due to the length it feels like a lot of the story is rushed to the end in the final episode. Which even though they made it make sense it did not keep with the overall pace of the anime as a whole. Just climax for the 9th and 10th episode then a straight end in the final episode. No gradual decline or a straight drop om a chart just a period at the end. Which really hurts the other all story in my opinion. I really hope there is a second season so I can edit this review.
