You were gonna die soon as you layed there, with your sword shattered around you. You were on the edge of death. You thought of death for a very long time and didn't think of it ending when your fighting against Muzan and his uppermoons....

Just as your about to die, you felt a liquid that taste like metal go into your mouth. Your eyes shot open as you saw Douma, Upper 2, by your side giving you Muzan's blood..
