I am convinced this is someone's favorite anime. I can see people completely vibing with this. It has good characters, good world-building, a good score (not even close to her best but a Yoko Kanno score is still a Yoko Kanno score). The show looks like a Yoshitoshi ABe show animated by Bones. Clean and clear, but still has that darkish tone.

This show is EXACTLY what I want out of adult animation. It's about a vigilante who takes down organizations of people with superpowers, and everything is given a down to earth tone. A realistic show with adult themes that is, well, dark. Also, I respect a show that isn't afraid to show blood while also not wanting to have Hellsing levels of violence.

However, being down to earth and going for an adults-only crowd (not in its content mostly, but in the way it tells its story) comes at a cost and that is that this show is boring. I thought it was going to be an ongoing plot about Hei's life living in that apartment complex while also living a double-life as a vigilante. Heads up, do not get attached to characters in this show. Not because it's like Danganronpa where your favorite character can just up and die at a moment's notice, but because this show is primarily episodic where every week (or actually every 2 weeks, I'll get to that in a bit) Hei goes against another part of the overall crime syndicate in Tokyo. This show is more about themes than an actual ongoing plot. I couldn't get attached to any of the characters and I don't think I have a "favorite episode".

This might sound like a petty thing, and trust me it didn't factor into my score, but I don't think this show should have been half-hour episodes. I get that with anime your show can't be composed entirely of hour long episodes, but the first 22 episodes of this show are all 2-part episodes. So I essentially watched 11 hour long episodes, plus 4 more bonus episodes (yes I watched the OVA). Honestly, I think it would have helped the show if every episode was an hour long. It sure would be daring, and also more similar to how live-action dramas are structured.

I'd say give the first two episodes a watch (don't watch this show in odd numbered chunks, that's weird) and if you are REALLY into it, I highly recommend that you keep watching. As for me? I'll struggle to even consider watching the second season.
