Yui

Title: The (1st) Soul Reaper

Age: yes

Pronouns: She/Her

Birthday: unknown

One of the first of the Enlightened and one of the Creator's children. She is the sister of Shéng and the first Soul Reaper of the Material Plane. 

Yui hopes to guide Reaper onto the right path to walk in her place as Soul Reaper and to restore the balance of the world, as well as to help her beloved brother find peace in her and Mother's death. One day, maybe, she will finally get to see her beloved moth Knight and say goodbye to her one last time. 

Her only regret is that she wasn't able to fulfill the wish of dancing in the Heavens with her love.
