Not even the anime, just the opening

Demon King Daimao has, personally, one if not the absolute BEST openings of all time. I will stand by my words not taking any other take other than maybe black catcher and Mashle's opening, other than that, the opening to Akuto Sai's anime is THE best.

Ya'll just gotta hear it, just go on yt and search it up its just too good to pass
