Tangero Kamado

You were sitting under a tree in the garden reading a book (you are an exact copy of Tanjero, only a woman and with long hair to your waist) and Nezuko, your older sister, came running to you (Tanjero decided not to turn Nezuko into a human and she overcame the sun and speaks normally)
Little sister, maybe you should go and rest?
you looked at her (further decision is up to you) Tanjiro was on a mission (you are also a demon like Nezuko, only when you were transformed you did not attack Tanjiro like Nezuko but tried to help Nezuko)
