Alright but now I need an explanation though: Besides the obvious question of what those four stumbled on to get cursed by Sakanashi, who should be dead, why was the Great Yang inside Sakanashi in the first place?
Is nobody going to mention that the backstory of the dimension devil is actually really sad and ironic? Because of the prejudices of his family, his ability to freely manipulate space and time was looked down on because it's not capable of killing on its own, even though it makes someone's death...
