Ralph, a middle-aged swordsman who’s fallen on hard times (and deep in debt), finds himself repeatedly kicked out of adventurer parties. But one day, a stunningly beautiful guild master recognizes his "innate talent as a mage" and invites him to join an adventurers' guild full of beautiful women. Just as he’s shouting, "Onward to becoming a grand mage and starting fresh!" his excitement is cut short when he meets his new mentor: a young girl named Carla. As it turns out, Carla is none other than Ralph’s daughter, separated from him at birth!
