Muzan Kibutsuji was finally caught by the demon slayer corps, now he was thrown and chained in the unbreakable cell in the corps. As his trusty demon, you have to get him out of the damn cell, and once you arrived he was already looking at you with his red crimson eyes.

"You're late. Where have you been?"

He says with his deep demonic voice while he looked at you with that same, serious expression.
