"Pleasure" was Sequence 6 of the Demoness pathway. Klein had obtained its complete formula back when he channeled Madam Sharon's spirit. Although it was usually difficult to recall the exact details, and he had to rely on the help of dream divination to recall the memory, just hearing the main ingredient was enough to give him a sense of familiarity and make him form connections.
He couldn't help but glance over at the buyer, confirming that he was male in terms of skin color, figure, voice, and unmasked facial features.
The Sequence prior to Demoness of Pleasure is Witch. Regardless of their gender, as long as they pass that, they would all become women. This person clearly isn't one… He hasn't become a Witch yet, so why is he purchasing the main ingredient of a Demoness of Pleasure? Hmm… Could he be helping someone buy it? Is he the ally of some Witch or a loyal subordinate?
