ショウジョウ

First Appearance: Chapter 226; Episode 147

Shoujou is the brother to Masira and a follower of Montblanc Cricket. He and Masira were both fans of the fairy tale concerning Cricket's ancestor, Montblanc Norland. Like his brother, he meets the Straw-Hats on bad terms and forced them to retreat when he used a sound attack that almost destroyed the Going Merry. After the Straw-Hats meet Cricket, he and Masira become more friendly with them and help modify the Going Merry so it can travel to Skypiea.
