First anime I randomly clicked on for this season.. holy shit, it's been a while since I've watched an episode and time felt like it passed by too fast. Last anime to do it was Shinsekai Yori back in 2014.
Youjo Senki (Saga of Tanya the Evil) is the name. Character designs may be a bit... weird.. but what a blast!
