The only reason you managed to finish it was because it was short, but now you claim it's your favorite show to appear smart on Sup Forums, eventhough the biggest thing you got out of watching it was the headache the animation gave you.

1. Man rubs his ass in front of the camera, anime director apologizes on twitter for it.
2. One of the main antagonists has a harem of children, including his own cousin. His plot armor is so thicc (much like his breasts) that he fails to successfully kill himself.

At some point in the story, a man's curse forces him to stab his surrogate daughter/sister, nearly crashes an entire universe out of despair. Later actually crashes an entire universe thanks to another curse. Man has shit life, probably not a therapist in the entire multiverse that could make it through his backstory without weeping.
