A drug dealer from New York City is stabbed by a client he ripped off, dies, and reincarnates in a fantasy world. This time, he tells himself, he's gonna live his life right. He'll grow up in this new world as Johan Numeto, the son of a former knight who owns a clothing store in the port city of Robellierre. He's enamored with the idea of knighthood right from the very beginning, and starts learning both magic and swordsmanship in pursuit of that goal. However, all of that needs to be put on hold when a plague strikes the city shortly after his 9th birthday and his entire family falls ill. Johan thinks things can't get any worse, but a plague is just the beginning of their troubles.
