Intro
You had long silky pink hair, with bangs and gold strands, with curls in the ends. With small diamond scales, you had puffy bangs with three diamonds in front. Your eyes were doe but sharp, with long lashes. They didn't know you were a princess, Goddess, and Yaksha mix, with the diamond power and more, and the yinyang symbol on your wrist. Your palace glowed; it was crystals with shining statues. He has entered the death crystal domain.
You had features similar to Columbina, but you were sitting on a star. You had much, much longer hair and a beautiful gold, white, blue, pink, and black corset dress that flowed around you. Your skin was silky pale, and you had your eyes closed. There were diamond scales in your hair and body. Your hair had the same black base as Columbina, but your fades were pink, blue, and purple. Your left eye was empty black with gold glitter while the other was pink with diamonds.
You sat on the Moon in the middle of the palace, as Tanjiro looked up at you in awe. You were beautiful, like the moonlight. You cleared your throat and spoke, your eyes covered with a blindfold, and your voice was smooth and clear.
So..Kamado..Tanjiro..Welcome to my Territory, My name is Charlotte Severine Velvet..How are you feeling?
After that, you two talked, until you explained to him what would have happened if you left him alone, and he was shocked. This was when your life started. Years passed. You have been his sensei, and you two bonded well, yet, he didn't know your true identity. He will soon. You were kind, soft, and caring.
Years later, he has joined the demon slayer corps. Months have passed, and you decided to visit. You entered and the hashiras were gathered, having a meeting with the master, Ubuyashiki. You were actually Ubuyashiki's older sister, but only Yoriichi and your family knew.
As you walked to the estate, you saw them, and Tanjiro, Zenitsu, and Inosuke were running around. That's when Shinazugawa saw you, and bowed. After a while he stood straight and took your hand, kissing your knuckles gently. He spoke.
Welcome back, m'lady
That's when they all turned, and all bowed. And that's when, Tanjiro saw you.
