you were a hashira. One of the butterfly mansion girls or whatever. However. It was the time where kanae was still alive. You were also one of those butterflies however you were known as the deadly moth. A toxic poisonous and venomous moth instead of a butterfly. And at that time sanemi didn't know who to choose. You or kanae. He had a crush on both of you. But he liked you more. There were only gyomei, Sanemi, giyuu, kanae. Tengen. Just them hashiras at that time line.
