Apocalypse no Toride

[The One Above God]

Synopsis:

What can you do when you get mistaken for murder? Nothing. You go to prison. Lucky you, your inmates are some of the biggest cutthroats in the prison. Seriously you are lucky. Especially when zombies attack.

Story: Yuu Kuraishi (Wagatsuma-san wa ore no yome)
Art: Kazu Inabe (Rock me Amadeus)

To be honest, I'm actually quite surprised that I don't see any thread of this here. Especially since this is a great manga, IMO.

Anyway, there are a lot of fucked up things you'll see in this manga. This isn't just the typical "zombie" apocalypse with the dead people walking around or running towards the nearest person they could infect. Things are much more than just that.

Also, pretty much all the recurring characters so far are great. All four of the MCs are badasses too. Interactions between them(the MCs) are great, and all their backstories are interesting.

There are a lot of nightmare fuel here so I suggest you don't read this if you can't stand those. If you're looking for something that will make you go "oh shit!" almost every page, then I recommend this.
