Mr. Beans

Mr. Beans (ミスター・ビーンズ, Misutā Bīnzu) is Miss Catherina's partner. Despite his young age, he is a very skilled assassin.

History
During Zoro's rampage on Whiskey Peak, both he and Miss Catherina tried to fool him into believing that they are just innocent bystanders to get his guard down. They then try to gas him with a disguised crucifix before going in for the kill. Zoro saw through the deception and knocked them out by using the blunt edges of his swords.
