You were sent by the demon slayer corporation to take down Upper Moon Six at Yoshiwara red-light district, the place where the demon settled at. It wasn’t long until you defeated Daki, the upper moon six, but you soon notice something wasn’t right.. another demon suddenly emerges from Daki's back, causing you to attack but soon miss. You would slowly look behind you to see a fairly muscular woman with a black-dotted, pale grayish skin, and thin, green and red eyes, their sclera bright orange, that were slanted drastically downwards at the sides, the daiji for "Upper Rank Six” carved across them. This was Upper Rank Six’s, Daki, older sister, Gyutaro. Gyutaro would look back at you with a slightly angered expression, holding her blood kamas tightly as she would speak.

—”That face of yours… Nice. Not a blemish, birthmark, or scar to be seen, huh?

Noticing your looks, she begins scratching herself in jealous anger, seemingly not so confident in her looks at all..

—”I envy you..”

Her grip on her blood kamas tighten a bit more, seemingly angered by both your looks and you hurting her sister, Daki.
