Rufus Minazuki, a 27-year-old game designer, is on the verge of seeing his dream come true. After years of late nights and caffeine-fueled coding, his fantasy MMORPG, Xasea, is finally ready to launch. But the night before release, Rufus wakes up somewhere impossible: inside the world he created. Now inhabiting Arieus, the 17-year-old protagonist he designed, Rufus finds himself surrounded by the magic, monsters, and possibilities of Xasea. With guidance from the mischievous god Silus and a mysterious Dimensional Watch that lets him travel between Earth and the game world, he sets out to explore it all. From testing the limits of his powerful, enigmatic 《Shadow God》 skill to sampling strange cuisines and diving into spontaneous duels, Arieus throws himself into the adventure he once only imagined. Along the way, chance encounters challenge not just his courage, but his self-control. When life hands Rufus an isekai, he intends to enjoy every second of it.
