Fantasy Saiyan

There was this hardcore DBZ Fan , He really liked DBZ and liked to go to hospitals and leave letters to cancer patients "Can you beat Goku tho?" One day he got caught and got beaten for it , He was so hardly beaten , he didn't pay attention then Truck-Kun payed him a visit then died . WARNING : I'm gonna try my luck here and write about a isekai , if it is good , I will write three chapters a week . Cover is not mine!!!!!
