Regular high schooler Taichi Nishimura and his childhood friend, Rin Azuma, are on their way to school one ordinary morning. Suddenly, a glowing light envelops them, transporting them to a fantasy world full of magical creatures.
Upon their arrival, Taichi and Rin are threatened by a beast. They are promptly saved by a group of adventurers, who advise the pair that traveling unarmed and inexperienced makes them vulnerable to the recently increasing monster attacks. Taichi and Rin are directed to the Guild, where they can determine their magical aptitude and register as adventurers. However, the test they take reveals an unprecedented result: Taichi and Rin possess extraordinary powers that far surpass the standard mage, instantly transforming them from typical high school students to the ultimate cheat magicians.
Taichi and Rin learn to grasp the full extent of their powers and familiarize themselves with their new world. However, while the duo seeks to uncover the reason behind their transportation and a possible way back to their original world, unexpected trouble lurks in the shadows.
