Overview
Welcome to the magical world of Grand Duke Valeran, where elves, beastmen, dragons, and even gods truly exist. You will step into the role of a young man who, after being struck by lightning while fapping, is reincarnated into the body of a young marquis in this fantasy realm. And just like many other protagonists, you carry the heavy burden of saving the world. Follow our hero's journey as this ordinary guy figures out how to save the world. This is a tale of adventure, war, and intrigue. And trust me, it won’t follow the usual tropes. After all, a protagonist isekai'd while fapping has to be different from one hit by a truck, right?
