Isekai Cheat Magician

Two typical high school students who also happened to be childhood friends are Taichi Nishimura and Rin Azuma. When a magic circle appears beneath their feet while they are walking to school, Taichi and Rin are both unexpectedly taken to a different planet named Altianutz. They are attacked by a nasty beast as they attempt to comprehend their current predicament. Fortunately, a band of intrepid travelers rescues them. When they reach a nearby town, they make the decision to sign up as adventurers themselves. They learn they have extremely potent magic and physical prowess while enrolling. They embark on their trip as the most formidable "cheat magicians" as a result. Taichi is forced to realize that a mystery woman who wants to exploit his power to determine the course of this universe willed him to be in Altia.
