One Piece Season 10 Episode 581 The Straw Hats Stunned! Enter: a Samurai's Horrifying Severed Head!

The Straw Hats are sailing through the New World when they suddenly stumble upon a strange island. As they approach the shore, they notice a group of bandits attacking a lone samurai. The Straw Hats quickly intervene and manage to defeat the bandits. The samurai, named Kin'emon, is grateful and explains that he is searching for his missing son, Momonosuke.

As they set out to help Kin'emon find his son, they encounter more mysterious occurrences, including a severed head that seems to be following them. Despite the creepy atmosphere, the Straw Hats press on, determined to unravel the mystery of the island.

As they travel further inland, they come across a group of people dressed in strange clothes and speaking an unfamiliar language. To their surprise, Kin'emon communicates with them effortlessly, revealing that he is a member of a powerful clan of warriors. The group introduces themselves as the "Wano Country," a land where samurai and ninja still exist and flourish.

The Straw Hats are fascinated by this new world they've stumbled upon and agree to help Kin'emon and the Wano Country in any way they can. However, their quest takes a dark turn when they discover that the Wano Country has been taken over by a tyrannical ruler, Kaido.

Despite the overwhelming odds, the Straw Hats and their new allies refuse to back down. They team up to take on Kaido and return peace to the Wano Country. But with Kaido's terrifying powers and vast army, it won't be an easy task.

As they continue their journey and face more challenges than ever before, the Straw Hats must rely on their strength, skill, and camaraderie to make it through alive. Will they be able to take on Kaido and save the Wano Country, or will they fall victim to his wrath?

One thing is certain: the Straw Hats are determined to see this mission through to the end, no matter what obstacles they may face along the way.
