A very good story involving themes like grief and sacrifice. The premise is solid, the characters are lovable. Not much to say about these types of anime in particular—they're generally hit or miss. You might love it, you might not. After all, emotional tear-jerking anime aren't for everyone. Now if I have to point out something, it's the choice of the name—it's actually brilliant. I don't want to spoil it so I won't explain, but the title itself is the main theme. This apocalypse anime focuses on survival from a different point of view. My final verdict: those who like tear-jerking anime must give it a try, and even those who generally don't watch these types can also try it—it won't be a disappointing experience.
