Down With The Demon King

After the battle at the Infinity Castle and the death of Muzan, the slayers faced an even bigger problem: When one of their own became the new demon king, able to withstand the sun. He was able to get away, leaving the remaining slayers defeated and injured. Nezuko, now human, vowed to be the one to behead her brother. She forms a team with Senjurou Rengoku, who took up swordsmanship once again, and Muichiro Tokito, who had to practically start over after a debilitating injury against Upper Moon One, to take down the new generation of demons and work to take down the threat and live in a peaceful world without demons.
