Demon Slayer: the Lord Is Actually Zero

**In order to end the curse that has haunted his family for thousands of years, he chose the darkest path. ** As the ninety-seventh generation master of the Demon Slayer Corps, Ubuyashiki Yoshiya has always been the gentle and noble leader in the hearts of all the members. However, when the curse increasingly erodes his life, and when he foresees that his daughters will make the same mistake again, at the edge of the abyss of despair, he makes a choice that shocks the world - to make a deal with Muzan Muzan and become the most hidden zero. During the day, he is still the lord who guides everyone to fight against evil spirits; at night, he is loyal to his thousand-year old enemy. When the truth was revealed on the eve of the final battle, the Demon Slayer Corps' faith collapsed overnight. The former "father" became the most hateful traitor, and the pillars who had sworn loyalty to him turned against each other one after another. But at the end of this sin-filled road, does Yaoya hide a trump card that can reverse the millennium? When wisteria flowers bloom together with blood, this chess game that began with betrayal will finally reach an ending that shocks everyone.
