Episode 581

"The Crew is Confused! The Shocking Beheaded Samurai Appears!" is the 581st episode of the One Piece anime.

Short Summary
Luffy, Zoro, Usopp, and Robin are standing near the dead dragon that Zoro killed and Luffy is trying to pull out the man who is stuck in the dragon's body. Luffy succeeds by pulling out only the legs, making everyone think that he killed the man. However, the legs are alive and they run away trying to look for a Shichibukai. Luffy runs after him and gets stuck to the legs after the legs fall on top of him.

Elsewhere, the Straw Hats who were captured by the people in the hazmat suits (Sanji, Nami, Chopper, and Franky) are in a prison cell and were shown to a gaseous figure known as "Master" who is very interested in Franky. They wake up minutes later in a cell and try to figure out how to get out. They then see a man's head which was cut into pieces and put it together. The head is alive and it tells them that his body was cut into pieces by a Shichibukai and he feels shameful for not getting killed after getting sliced.

Back with Luffy's group, Usopp sees a harpy girl on top of a burned down building, but after he yells for everyone to look, she disappears suddenly. They then approach a lake that separates the fiery and icy halves of Punk Hazard. Luffy befriends a centaur that thought that Luffy was one of his kind. The people of Punk Hazard who work for Master see Luffy's group and tell the harpy girl about them.

Long Summary
Luffy, Zoro, Usopp, and Robin are standing near the dead dragon that Zoro killed and Luffy is trying to pull out the man who is stuck in the dragon's body. Luffy succeeds by pulling out only the legs, making everyone think that he killed the man. The legs are revealed to be alive, making the whole group gawk at it. Robin points out that there was no trace of an upper body while Usopp states that he is quite tall. While the crew remained baffled, the legs start to attack them but promptly run away after the unknown [Shichibukai]]. Luffy is then seen calling to it to join his crew, making Usopp tell him to stop it. Luffy runs after him and gets stuck to the legs after the legs fall on top of him.

Luffy is having fun with the disembodied legs, sticking the waist to his own and calling himself a centaur. He tells the legs that he ate dragon meat, so he has dragon powers. Robin tells Luffy that what he is doing is simply vulgar. Before Luffy can do anything else, the legs lift Luffy up and piledrive him into the ground. Usopp tells Luffy that there must be an upper body in trouble somewhere. Luffy tells Usopp he has no imagination. He is about to name the legs when they piledrive him again. Zoro calls to the others from atop a building. He points and the crew realizes they are standing right next to a lake, beyond which is a mountain range covered in ice. Usopp and Robin realize that the distress call they received was coming from the cold side of the island. Luffy is excited by this and wants to eat shaved ice. Usopp, while shouting at Zoro (who, along with Robin, wants to explore the island with Luffy), senses something strange on a nearby chimney. He looks over to see a smiling winged woman staring at him, who then flies off like a bird. Usopp tells the others about what he saw but is not sure about it himself.

In a laboratory, a guard walks in to inform the master of having kidnapped Sanji, Nami, Franky and Chopper and the master is very pleased, especially over Franky's cyborg body and chooses to experiment on them later as he tells his men to lock them in a room. Back on the Sunny, Brook, having been left behind due to them believing he was already dead, wakes up while some guards are still on the ship and demand to know who he is.

Later, Franky wakes up to the sound of Sanji kicking the wall and asks what is wrong. Nami tells him it should be obvious and Chopper tells him they are locked up. The crew tries to remember the last thing they did, and Nami realizes that whoever took them must have hit them with sleeping gas. Sanji confirms this. Franky then wonders where Brook is, and Chopper asks why someone would kidnap a skeleton. From one corner, a voice asks them if they like riddles. The group looks around for the source of the voice, and Chopper jumps back in shock. The voice is from a mouth that is one of eight pieces of a disassembled man's head. The man asks if they could put him back together. Each member gives it a shot, and they finally get pretty close, having only mixed up the hair and chin, but the samari admits his gratitude regardless. Chopper asks him why he is alive, and the head says he does not know as he was cut up by someone and claims he feels shameful for what happened.

Back with Luffy's group, everyone except Usopp plan to go to the cold side despite his protests as Luffy runs into a centaur with leopard legs and mistakes Luffy as an intruder and the two become friends talking about there legs as Zoro and Robin note he's made another weird friend. Above them, another person is watching them and informs the bird woman Usopp saw earlier is asking if the intruders were found. A person on the other end of a Den Den Mushi says they are bringing them down now as the bird woman flies away pleased flying in the cold side of Punk Hazard.
