Haven't seen Asterix Wars, The Perfect Insider or Gundam. I did however, recently watch The Flowers Of Evil which is a cringy psychological romantic clusterfuck that I'd recommend. Like Kamisama Dolls though, it never got a second season, so to get the full storyline you're gonna have to read the manga. I also watched Terror In Resonance from start to finish in one sitting, which is loosely about terrorism. I've started watching No Game, No Life and I'm not sure what to think of it yet.
