Story (8/10):
The story of the anime is of the meaning behind life and death, people who accept their fate and live waiting for their "Time" to come and people who fight against fate, and you also have a war going on
The concept of the anime was really interesting whither it's the reincarnation through the dragon teeth or the way the people coexist with the dragon. The whole world in the anime felt original and the mixture of modern life and mythical creatures was really well executed.
Characters (8/10):
The characters in general were great and had simple motivations and goals which is a good thing for a short 2 episodes anime (even if the episodes are 45mins) they were introduced quickly and given enough development to sustain and move the story along
Art and Animation (7/10):
The art style of the backgrounds was nice and well drawn although not really colorful.
The CGI used for characters and objects was not half bad, it only crapped out in some scenes
The animations for movements and during action scenes were really good and felt smooth
Music & VA (7/10):
The music was nice but not very memorable, even though i finished the show just last night i don't recall any of the soundtracks
The voice acting was good. Voices fit their characters and there was no annoying voices
Effectiveness (7/10):
Having an original concept really upped the enjoyment of this anime and with solid action and a decent story this was really a blast to watch
Making this into a full lenghth show would have been a better choice, giving more details about the world and characters and giving a less open ending.
Overall (7.5/10)
