Satoru Karayama is a somewhat lonely university student living an uneventful and boring life when, one day, he suddenly gains an extraordinary ability: teleportation magic that lets him instantly travel anywhere he wants. At first, Satoru secretly uses his newfound power to make his ordinary life a little more convenient and exciting. But his understanding of the ability changes completely when a mysterious beast-eared girl named Lily suddenly appears before him, or rather, when Satoru realizes that he has somehow teleported to an entirely different world.

His magic isn't limited to moving around Japan. It can take him back and forth between the modern world and a fantasy world. With virtually unrestricted teleportation at his disposal, Satoru begins enjoying the best of both worlds, meeting new companions, getting involved with girls ranging from a high-school idol to otherworldly beauties, and using his ridiculously versatile ability to overcome whatever problems come his way. What was once a lonely and monotonous existence transforms into a carefree life of adventure, romance, and otherworldly excitement, all thanks to one absurdly convenient spell!
