While testing his brand new VRMMO, Reito Kanzaki was trapped inside the game for three years. He defeated the final boss of the game and was finally freed, but what he returned to was that something odd happened to the real world. A "little sister" of his out of nowhere, Reito can still use the same ability as in the game, and monsters appear. Will Reito make use of his overwhelming power and become the savior of this world??
