No game no life: zero takes place 6,000 years ago in the midst of the "eternal war" where 15 gods all thought that they were the one true god. What the gods do to determine the one true god is try to kill each other. Each god created a different and somehow unique race. There are dwarves, fairies, elves, flugels, humans, warebeasts, etc. The gods gather their armies and go to war. The 2 main protagonists are Riku who is a human fighting in the war and Schwi who is an ex-machina who separated herself from the system to learn about the human heart and emotions. I say that this is a must watch because it really made me feel for the characters and I was also very entertained. The ngnl anime series was where all conflicts were solved with games. The reason for that is because this eternal war was so violent and horrific that the last god remaining had to ban all acts of violence. So I like the change from happy go lucky characters with not much to worry about to people who are aware that they could die at any moment. The fight scenes are amazing and the it also really pulls on your heartstrings. I love this movie to death and I recommend that you watch it. Watch the series first if you haven't seen that because it pretty much requires you to have at least some knowledge about the world that it takes place.
