An unambitious medical undergraduate from Earth, who spends his days flirting with beautiful women for fun, was unfortunately sucked into an alternate world, the Divine Wind Continent, by a black hole during an extremely heavy thunderstorm. This is a strange land different from the real world, where advanced creatures of various races coexist with fierce magical beasts. In this cruel world that takes the law of the jungle and the survival of the fittest to the extreme, with his pitifully weak strength, how can he use the medical skills he has learned to survive tenaciously and even rise to prominence?
