“Why did you let Kuro of a Hundred Plans get away?” Beluo kept demanding of Luffy.
The protagonist’s village was raided by Kuro of a Hundred Plans, who had been defeated by the Straw Hat Pirates and was now out of his mind. When the protagonist returned, all he found were the villagers’ cold, lifeless bodies.

In a dog-eat-dog world, instead of thinking about how to become stronger, he just wants to coast through life—is that really the mindset of a normal, mature man? Any normal One Piece fan knows how to make choices in the world of One Piece.
