Plot
In a world where people gain Skills from eating Skill Fruits, Light and his friend Lena dream of becoming adventurers. When they eat Skill Fruits, Lena gets the legendary "Sword Saint" Skill, but Light gets the "Fruitmaster" Skill, which lets him grow fruits more efficiently. Since eating more than one Skill Fruit is fatal, Light is resigned to living as a farmer, until he accidentally eats another Skill Fruit and discovers the true power of his "Fruitmaster" Skill: it grants him immunity to all poisons found in fruits, making him the only person in the world who can eat multiple Skill Fruits without dying, allowing him to get as many Skills as he wants.
