Hey, since it's been on my mind recently, Mousou Dairinin, or as I better know it, Paranoia Agent, is gonna be my pick for you this month.
I dunno if you've ever touched any of Satoshi Kon's stuff before but...this is a pretty alright showcase of his work. He mostly does movies tho and if I had the choice, I'd probably throw Perfect Blue your way since that's my favorite thing from him. But yeah, just give this a look and OH GOD YOU ALREADY WATCHED IT DIDN'T YOU
