Shakugan No Shana is based on the manga of the same name and tells the tale of Sakai Yuji and Shana. Yuji is a normal high school kid, living life in the same boring manner as everyone his age does. One day he's walking to school with one of his classmates when suddenly the world around him changes color to a horrible tint of red and purple.

Everyone is frozen, except for him and a Monster callled a "Guze" that starts devouring everyone. Suddenly to save the day there appears a flame haired girl in a coat ,wielding a Katana. She takes down the monster effortlessly, and from that point onward, Yuji's life takes a very eventful turn for better or worse.

Overall, Shakugan No Shana's a nice, neat and fun experience. It's not perfect, and it's not something that EVERYONE will love, but it's still great stuff none the less... Full Review
