Lynch, a 28-year-old useless screenwriter who was laid off, dreamed of traveling through time before he finished writing.
When he woke up, he found that his soul had traveled through the world of pirates, and he had accidentally eaten a strange devil fruit - the Useless Fruit, which has the ability to turn all "useful" things into "useless".
The sea beast turns into a salted fish, the famous sword turns into a tickle, the Sixth Form of the Navy turns into radio gymnastics, and the natural ability turns into a marshmallow...
In this world where fists are king, he chose the most outrageous path - using his "useless" abilities to live up to the funniest legend.
