Oh ho, interesting! I’ll definitely check it out. Manga or anime? I mainly read manga now so if there’s that I’ll check that out.
It has both, but it started as a manga and it’s vastly superior (unfortunately, Studio Pierrot is animating it, and it’s less than stellar with more filler than there should be).
Though, even though the anime isn’t great, the OP is amazing and works really well for showing everything off
(yes, it’s the second OP, but tbh it’s better than the first one)
