(Crossover) Saber Sanada Nobuzo's Life in Another World

[The My Hero Academia section is locked, so don't bother reading it. The Mononoke section is open.] Sanada Nobuzo is a walking contradiction. He possesses both a demon lord's emptiness and absurdity, yet insists on clinging to human morals and convictions. After a witch dragged him back from hell to the human world, he set out to repay her by traveling to various worlds in search of a way to return the favor. What might happen in those strange and mysterious places? Let's wait and see. A crossover fanfic. My first attempt at a medium-to-long, plot-focused fanfic. No outline, no chapters in reserve, no set pairing (probably none), irregular updates, but I definitely won't abandon it. As for the pairing, I don't know either... I still don't think I can write Todoroki well, so let's just leave him in the past. The Mononoke arc has begun and should end soon (it's a very short arc). What I write next depends on what I'm watching or playing at the time. Theme:
