Let me preface this by saying, once I start watching something I have to see it through. This is one of the reasons I'm particular about what I watch.
This anime really ought to have not been made. It's pretty dull and almost does the entire anime industry a disservice. I rated and wrote a synopsis for every episode so check that out if you want to get a feel for what happens in this series I won't spoil it in case you think I'm just hard to please.
The mindlessness in the premise, the way the story unfolds and the like it's as if someone watched Deathnote in its prime plus some of Attack on Titan with a little Tokyo Ghoul and said hold my beer! Not in a good way though. The shows I've just mentioned have some major flaws (not doubting they are entertaining) so if someone found the path between them it would be a good show. This is not it. Mindless slaughter and characters as disposable as paper plates there is nothing holding this story together. The animation is clunky during fights and overall as I said the resources might've been better served elsewhere. Knowing how much time it takes to bring an anime to life gives me no joy in effectively trashing it but this does little to justify your time. Move on to better shows.
The ratings I gave the episodes were based on the first episode onwards not against other anime in case you were wondering. So a 6 in an episode is a 6 compared to other episodes within the series and so on...
