Synopsis
Our hero had nothing going for him until the day he was lucky enough to be reincarnated in a fantasy world like he'd always dreamed. Unfortunately, he didn't get any of the special powers that usually entails, so he was still just an ordinary guy. Eventually he was subjected to a magical drug trial by the ill-tempered mage Luka -- and it worked! His power awakened! The power to see a girl's most sensitive spots and fetishes. A rousing success! With his new ability, all the beautiful adventurers in the world can be his! [Edited from [url=https://www.dlsite.com/ecchi-eng/work/=/product_id/RE292818.html]DLsite English[/url]]
