Demon Slayer: Kimetsu No Yaiba: Yin Yang Realm

The time traveler Mo Xie mistakenly enters the underworld, a ghost-destroying world that is reversed from the yang realm: people in the yang realm are ghosts here, but the evil ghosts have become humans? In the underworld, the 12 pillars led by the Lord continue to enslave ghost slaves. The ghost king in the yang realm, Wu Mei, turns into the leader of the resistance army in the underworld, joining hands with the 12 Lieyangs (including Hei Shimo, Yiwo Zuo and others) to fight together. Moye awakens the breath of death and joins the resistance to reveal the truth about the underworld. Only he and Ji Guoyi can travel back and forth between the two worlds.
