The War is about a rebellion due to the disobedience to god that a male angel fell in love with a woman.
---some basic level of description can also be seen in the AMV though not until very late.
In fact, half of the time, if you think this is an AMV simply talking about the anime Fate/Zero, I think it is still ok. At least this is what I intended to do initially, but I changed my plan for whatever reasons.

Side notes:
Welcome to the world of 1/30 sec! It is my pleasure to join this community, and this is my first time to participate in an AMV contest. I sincerely hope you enjoy this project, or at least I do so. However, I also deeply feel that there is still a long way for me to achieve my expectation in this field. So far I have multiple projects on hold along with my busy university coursework. I hope next time I can go farther.
