Not too long ago there was a peaceful and boring town called Munchia. It was a town of love and care. Everyone was very kind to each other and treated each other like a family. Kuso was a young male who was just going into his first year of high school. He was always naughty and loved to prank people. During his first year of high school, he went overboard by continuously playing pranks on his new classmates. As a result, everyone got fed up and wanted to play a prank on someone else. It went from students to teachers, from friends and families and the chain continued. As time passed by, it became such a huge chain reaction that the whole town started playing rough. Everyone started fooling around, being crazy, and especially making practical jokes. The whole town became a place of excitement and later on the town became known as the Kuso Party along with Kuso being the leader.

Now newcomers are joining the wrecking mayhem and fighting their way up the ranks. Having the lines of wild thoughts and creative tricks, which include being mad, childish and crazy, they unleash their mischievous inner selves. The crazier a person is, the more famous he/she becomes in the Kuso Party.

As they become good at what they are doing, maybe one day they will even try to take on Kuso.
