Zeke jamás peleó contra nadie en todo el anime, era un clon, solo se quedaba lejos lanzando piedras, pero nunca la armo contra nadie, Levi tantito que lo tuviera cerca y lo hacía cagada las veces que sea.
Demon King Tanjiro 1.He is literally immune to the sun. 2.He is Immune to Yoriichi's Sword. 3.He Can Regenerate. Although Yorrichi is strong The Main Character/Demon King Tanjiro Wins. Correct me of im wrong.
He isn't immune to his sword it's just that the sword doesn't do extra damage like it would to a normal demon and Yoriichi easily killed Muzan and with Yoriichi's speed I don't think demon king Tanjiro would win imo!
