God makes a careless error and unintentionally kills Touya Mochizuki with a lightning strike! God grants him one wish as an apology and the opportunity to start over in a fantastical fantasy realm. Touya gladly accepts the task and makes just one request before setting off on his adventure in this enigmatic world: that he be allowed to keep his smartphone. When Touya first enters this new world, he discovers that it is full of gorgeous girls competing for his attention and magic, a subject to which he has an affinity. These girls—Yumina Urnea Belfast, Leen, Yae Kokonoe, the twins Linze and Elze Silhoueska, Leen, and Yae Kokonoe—offer Touya a never-ending supply of love difficulties as well as company while he learns the details of this new society.
