The story is very interesting, and includes many plot twists and wandering questions that will be answered at the end. It includes lots of strategical ideals, which makes it more thrilling. However, the main female character is the only thing I don't like about this anime. She is annoying, hinders in the main characters affairs, and only serves as fan-service love interest. Even at the end I hated her! If you ignore her, than you'll definetly enjoy this anime!
