Suddenly a high school student Subaru Natsuki has been summoned to another world on the way back from the convenience store. With the biggest crisis of his life being summoned to another world and no sign of the one who summoned him things become worse when he is attacked.

On just another normal school day, while 16-year-old Drake Wilson drives his two best friends, Mike and Chad, to school, an unexpected twist of fate occurs in the form of a cat. When a cat runs across the road, Drake narrowly misses it, and his car ends up driving into a nearby field. With a sudden storm, a flash of light explodes, creating a dimensional portal in front of them. There is nothing they could do to stop the car from entering the portal. On the other side, they find themselves in another dimension filled with magic and power. To Drake, the place looks familiar because it is the starting point of his new game called “Dimension Master.”

What the hell is this? What the hell happened here?
