Only watch this show if you're bored or yearning for a 90's anime. The characters are lacking, the story seems forced, and on top of that it's average 90's looking. The only plus side is that it's only an hour short.
The story throws you into mid-scene of apocalyptic earth with 60% of the population dead from nuclear war, but you don't know why. The relationship between each character has no reasoning behind it. Just from these facts alone, the show already sucks.
I had to continuously scroll through the second episode to get to the end because that's how bad it was. Do not watch.
