Volume 4: The Slope

Kurahadol or Captain Kuro is a very cold-blooded man. He has given up his pirate life to become Kaya's caretaker, because he wanted her money. Kurahadol was sick and tied of being chased by the Marines, so he tried to find a peaceful place to stay. It's been three years since Kurahadol arrived at the village. During those three years, he has established a good reputation with the villagers. When Usop warned Kaya, Kaya was mad at him and one of her servants shot at him!
The mystery man that Kurahadol talked to was Jango. Jango is currently a captain of the Kuro-nego (black cat) pirates. He's able to hypnotize anyone. Other members of Kuro-nego pirates include the Nia-bun brother, which are Buji and Chamu. Zoro almost gets killed by the Nia-bun brothers, but finally, Zoro is able to defeat them. Kurahadol was upset that his plan was ruined, so he decided to kill everyone! Now Luefy must stop Kurahadol!
