Slow Life In Another World (I Wish!), Volume 6

Itsuki finally spent his first night with Wendy. But he's barely basked in afterglow when the feudal lord of the city, Origoll, shows up to berate him for all the trouble he's caused in town. When Origoll suddenly falls gravely ill, however, Itsuki is determined to help her and puts his alchemy skills to the test to prepare a remedy. Yet nothing seems to work! Finally, he recalls the elusive miracle drug he'd managed to concoct by accident. Will he be able to re-create this life-saving cure in time?
