God, in an unthinking error, inadvertently kills Touya Mochizuki with a stray bolt of lightning! As an atonement, God grants him one desire and the opportunity to relive his life in a magnificent dream realm. Touya gladly accepts the offer and, in exchange for one desire, requests that he keep his smartphone with him as he embarks on his voyage into this mystery land. Starting again in this new world, Touya discovers it is full of magic, which he enjoys, and gorgeous girls competing for his attention. These girls—the twins Linze and Elze Silhoueska, Yumina Urnea Belfast, Leen, and Yae Kokonoe—not only give Touya with romantic challenges, but also friendship as he learns the secrets of this new world.
