Demon Slayer: Dressed as the Lord and Bound to the Cub Raising System

[The cub-protecting demon lord × the combat power of all members has soared, specializing in the treatment of ghosts that are difficult to quell, promised HE] Dressed as Ubuyashiki Yoshiya, the Demon Slayer leader who was cursed and had only three years left to live, Lin Che bound the [All-member Cub Raising System] in despair. "Adoptable cubs detected: Tanjiro who bears a blood feud, Giyuu who closes his heart, Anjurou who burns too much, Butterfly Ninja who hides his sword with a smile..." From then on, the sickly lord began his daily routine of protecting cubs: Make hot soup for Tanjiro and tell the boy "your sister will definitely turn back into a human"; Chase back the volunteer who went on a mission alone and give him a hand warmer and healing medicine; Anjuro, who was trained until he fainted, was held down and issued a "forced rest order"; Staying outside the laboratory until late at night, he whispered to Butterfly Ninja: "I will accompany you on the road to revenge." He used systemic elixirs to alleviate the curse, used modern wisdom to reform the Demon Slayer Squad, picked up Zenitsu, Inosuke, and Kanao one by one, and told them: "You are not monsters, you are children who deserve to be loved." When Wu Mei finally came to the door, what he saw was—— All the pillars have advanced, and the swords and patterns have opened up; Tanjiro's breath of the sun lights up the night sky; even Nezuko, who turned into a ghost, stands in the sun. And the lord who was supposed to be dying was holding the Sun Blade and smiling: "Let me introduce, these are the cubs I raised." "Today's goal is to make you disappear completely."
