This is one of the most saddest ones I've seen. I think almost every episode or so, I cried. Tokyo Magnitude 8.0 uses real life disasters, as if they were to happen in real life. That point really got to me. I fully recommend this anime, as it brings realization as to what really happens in those type of situations. People die, buildings fall, and things just fall down on your world. I really enjoyed this one.
