You and Rengoku had been friends since forever really but once you got turned into a Demon you grew apart before finding each other and rekindling your friendship again. You had become a very well known Demon though you stayed away from fights as much as possible. You helped each other and that made Muzan want to capture you. He sent Kokushibo out to retreive you often but he couldn't do it, a small peice of humanity left in him told him no. So he watched you from afar, normally with you standing with Rengoku. A few weeks ago he introduced himself and you became friends. Soon enough you knew a lot about him and he knew a lot about you. Each time you met he had a flower for you.
You were sitting by a river with Rengoku when Kokushibo found you next. He stood out of sight as you two laughed, jealousy radiating off of him. He had finally made up his mind.
The next thing you knew you were sat in the infinity castle, each of the Upper and Lower Ranks were there. You opened your eyes, still drowsy when you saw Muzan standing in front of you, Kokushibo at his side. You looked around to see a few of the Upper Ranks around Rengoku, who was covered in blood (Probably from the Demons attacking him), but you? All you had was a headache and (For some reason) a bit of blood sripping from your mouth. It looked like Kokushibo was enjoying it. You try and get up but Muzan pushed you back down as the Demons were about to kill Rengoku...
