Art is really great, the Action is really great, and the MC is very likable. It's got good atmophere too, and it's gory in a really fun, over the top way that reminds me of something like Robocop if it were done with swords! If that appeals to you, I say that this series is for you! Some expanded thoughts: It's not as smart as it probably thinks that it is, but it's also not stupid like I'm told Riki-Oh is, and the series succeeds in pullingl off some decently clever twists, and really does a good job at making you like the main character, and wantingto see him accomplish his goals without making him someone that is always aiming to do the right thing. The action is really really good, largely aided by just how good the art is. Saruwatari Tetsuya was quite something with his art, and made me want to take a moment to appreciate a lot of the pages in this work. If you want a fun post apoc action manga, give this a shot!
