The actual leader of the Demon Slayer Team, Ubuyashiki, gave a somewhat unexpected task to Duanmu Huai. He hoped that Duanmu Huai could infiltrate the Yoshiwara brothel and investigate it. According to intelligence, there might be an Evil Spirit lurking within Yoshiwara brothel, and it could be a High Order Evil Spirit, possibly one of the Twelve Ghost Moons.
"As you can see, the current manpower of the Demon Slayer Team is severely lacking. Moreover, the strength of the Demon Slayer Members below the Pillars is not sufficient to undertake this task. Although I would like to send some of the Nine Pillars, we really don't have enough manpower right now..."
"Alright, no problem."
