The actual leader of the Demon Slayer Corps, Ubuyashiki, had an unexpected task for Duanmu Huai. He wanted Duanmu Huai to infiltrate the Yoshiwara Pleasure District and investigate it. According to their intelligence, a demon was very likely hiding within the Yoshiwara Pleasure District—and not just any demon, but a high-ranking one, quite possibly one of the Twelve Demon Moons.
"As you can see, the Demon Slayer Corps is severely short-handed right now, and the strength of our members below the Pillars is insufficient for a task of this magnitude. Although I would like to send some of the Nine Pillars, we're simply too short on manpower at the moment..."
"All right, no problem."
Duanmu Huai agreed without the slightest hesitation. He had visited the Yoshiwara Pleasure District in another world, though unfortunately, it had been a gathering place for an evil cult at the time. Besides, modern pleasure districts always lacked that certain flavor. If you wanted to experience a pleasure district from the old days, you had to visit one in the old days to get the authentic taste!
Now this is the real Yoshiwara Pleasure District. How could I pass up the chance to see it?
"Then, once I arrive in Yoshiwara, who should I contact?"
"Well..."
Hearing Duanmu Huai's question, Ubuyashiki gave a bitter smile.
"I'm afraid you'll have to investigate on your own, because... we only managed to gather some information..."
"..."
Faced with Ubuyashiki's answer, Duanmu Huai fell silent.
"In other words, the Demon Slayer Corps has no intelligence-gathering outpost in the Yoshiwara Pleasure District, and I have to start from scratch?"
"That's right..."
"What kind of ramshackle operation are you running..."
Duanmu Huai tilted his head back and covered his face, utterly speechless.
Demons couldn't act during the day and only moved at
