I have seen Tsunayoshi transform into Xanxus, and I have also seen Tsunayoshi transform into Byakuran, so it is like writing about Tsunayoshi transforming into Uni. In this story, Uni did not inherit a sad fate, but grew up and lived as an ordinary girl, and her mission was taken over by Tsunayoshi.
This is my first novel and the writing is not good. Please correct me if there are any mistakes.
