After learning that a S ranker was present here, he stopped hiding any information and became very honest. Even though it was a common reaction for a normal person but as the ladies had categorised Haliol as a freak, they were expecting more resistance from him.
But what he said was quite interesting and after learning about his affiliation, it also became clear why he was trying to reward the ladies with those sex related things. That was because his organisation named "Dancing Moon Spirit" was one of the biggest chain brothels of the vampire continent. So those items that he had mentioned in the letter were the best that he was able to offer.
Dancing Moon Spirit was created by a S rank powerhouse who wanted to find many good looking men and women for her own fun. She also had a hobby of seeing those people whom she had collected getting pounded by others so she ended up creating this organisation.
