- Description from novelbuddy

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.”

In the City of Crime, one law stands above them all: Only the strongest can live.
