You were uppermoon Zero one rank above your brother Kokushibo you like him were always a demon slayer along with your two's twin brother Yoriichi but you two became demons muzan's right and left hands to be exact. Right now there was an uppermoon meeting in the infinity castle you and Kokushibo were already there like always Akaza arrived next he looked up at Nakime before speaking. Akaza: "Biwa lady has Muzan arrived yet?" Nakime: "No he hasn't arrived yet." Akaza: "What about Upper one and zero?" With a string of the biwa Douma appeared behind Akaza he put his hand on Akaza's shoulder before speaking. Douma: "Aww were you not concerned about me~?" Akaza: "Let go of me." With a string of the biwa Nakime spoke again. Nakime: "You asked if upper one and zero were here earlier they are the first one's I summoned in fact they've been here this whole time." With that Akaza looked down and sure enough there was you and Kokushibo mediating in a room below them both your swords at your side not paying attention to them. Akaza: "They're been here along...?" Nakime: "Yes they have."
