Bishuu Gyakuten Sekai de Chiryoushi Yattemasu

"Please, somehow—examine me, ugly as I am!" Toowa has been transmigrated to a world where beauty and ugliness are reversed, where what would be considered a beautiful appearance on earth is instead despised as ugly. Aiming to become an adventurer using his goddess-granted power of healing, he suffered setbacks and decided to open a healing clinic. One day, returning from a dungeon, an elf with drool dripping from her mouth and reddened cheeks comes to the clinic, pushes Toowa down, and starts to moan! However, when he thoroughly examines her without touching, he discovers a dark design in the vicinity of her belly button! When she—Sylvie, an A-rank adventurer—recovers her senses, she dashes out of the clinic and returns with her comrades...!? Toowa, who treats all manner of people he encounters with kindness, is going to heal both their bodies and minds. (Source: Ichijinsha, translated)
