It's all about surviving with a twist, it's such an engaging series and the manga isn't half bad either I recommend it, however, you may or may not have to rewatch the last 2-3 episodes again... Why? I guess you'll just have to watch it to find out XD
The characters all have their perks and some I disliked at the beginning but they somehow made my love them at the very end, however, some still don't like hahaha but they can't change that now they... But I'm sure there is a character in this series you'll love or love to hate :)
Only probably I personally had is that the ending is pretty disappointing in a way, though, there is "redial"(the ova) that gave this show a somewhat proper ending? lol
But still high recommend it :)
