Sancrin

Sancrin the Thief is a member of the Longarm Tribe and Brook's former manager.

Appearance
Sancrin has a mustache which he shaved off as Brook's manager and black hair. As a longarm, he has double-jointed elbowed arms. While still a kidnapper, he wore an orange Chinese garb with the kanji 盗 (tō, to steal) on it. As Brook's manager he wore a yellow suit with a red shirt underneath, and a black bow tie. He also wore red sunglasses with blue lenses.

Personality
He is greedy and opportunistic, kidnapping humans in order to exhibit them, and then taking advantage of Brook's mercy to kidnap him for the same reasons. Sancrin shows that he did not believe in devils and occult, as he was not afraid of Brook of being a skeleton, despite not knowing he was a Devil Fruit user at the time. When Brook was planning to retire from the rock band industry to return to his crew, Sancrin was fully willing to betray him to the Marines to gain some last minute benefit (the bounty on Brook's head) and revenge, and even held him at gunpoint to prevent him from escaping.

History
He first appeared on Namakura Island along with two other longarms in order to kidnap some of the villagers. Brook was able to rally the citizens to fight them. The villages however lost and Brook had to defeat the longarms on his own. They tied up the longarms and put them in a cage. Brook later decided to let them go free. Upon their release, Sancrin and the two other longarms kidnapped Brook and put him on display back at their home island. When it was discovered how musically talented Brook was, Sancrin became one of his managers.

Before Brook's concert on Sabaody, he told Sancrin that this would be his final show. Sancrin at first seemed more shocked than annoyed. He later called the Marines during the concert to inform them that the music star Brook was actually a pirate. He was very angry when Brook escaped.

Trivia

 * At one point in both the manga and the anime, Sancrin mistakenly loses his mustache. Ironically, both medias made this mistake during the same scene.
