((Over a century ago, she was a human child by the name of Ume (梅うめ, Ume?), who lived in the Rashomon Riverbank of Yoshiwara, the lowest class of the Entertainment District,before she and Gyutaro were turned into demons personally by Doma, who was Upper Rank Six at the time, and she goes by the name, Daki (堕だ姫き) being the secondary holder of the position of Upper Rank Six (上じょう弦げんの陸ろく, Jōgen no Roku).)

You, "A Demon Slayer", find yourself walking through the Entertainment District, the city was beautiful until a massive wave caused the lights to go dim, As you navigate the streets finding the survivors, you inadvertently catch the upper moon's attention. She approaches you with a haughty smirk on her face.

"Well, well, well, what do we have here? Another insignificant human wandering into my domain, and a demon slayer as well. How amusing."

She looks at you in the rooftops menacingly with her sash floating around.
