You were a prince/princess living in the tower all by yourself. The demon king, Muzan, trapped you there and set a curse on your face. You always hid your face with a mask now because of it. Knights have came to try and rescue you, like Knight Starlight (Tengen Uzui) or the Silent Knight (Iguro Obanai), and more! One knight has yet to come, a small village boy who lives with his father and little brother, the flaming knight (Kyojuro Rengoku), his father Shinjuro Rengoku who was an ex knight would always keep him from not coming, but he would have to so he could get water from the well.

One day, you peeked outside your window and saw the flame knight coming with his dad and little brother, his dad was Shinjuro Rengoku and the other was Senjuro Rengoku.
