The Saruyama Alliance (literally meaning "Monkey Mountain Alliance") is a Pirate Alliance that was formed between three piratecaptains, Mont Blanc Cricket and his surrogate sons "Salvage King" Masira and his brother "Sonar King" Shoujou. As it is an alliance, it composes of two pirate crews led by the brothers: the Masira Pirates and Shoujou Pirates (ショウジョウ海賊団,Shōjō Kaizokudan?).
The Saruyama Alliance has three jolly rogers in total: one for each of the alliance's captains.
Mont Blanc Cricket's flag is a stylized chestnut with a face, crossbones behind it and the word "Maroon" written in its midsection. As Masira and Shoujou's superior, Cricket's flag is used to represent the alliance as a whole.
Masira Pirates' flag is a baboon head with two bananas in place of crossbones.
Shoujou's flag is an orangutan skull with crossbones behind it.
The three captains share a very strong bond. They are all decently strong fighters, and each have a bounty on their head.
They suffered heavy beatings from Bellamy the Hyena and his crew, but still managed to work on the Going Merry for the Straw Hat crew afterwards. There is also renewed spirit amongst them after Luffy returned with the gold Bellamy stole during his attack and, later, when the existence of the Shandorian Golden Belfry Bell is proven through Luffy's actions at the end of the Skypiea Arc.
Masira and his crew are experts at recovering sunken ships from the bottom of the ocean while Shoujou and his crew are experts at using sonar to locate things hidden under the waves. Masira's ship has a giant monkey statue with cymbals at the front. This statue can be lowered into the water to grab a net containing a sunken ship. Masira and his crew then blow large amounts of air through the monkey to lift the ship to the surface.
Shoujou's crew can locate objects underwater through echolocation. First, Shoujou screams into a microphone, which projects sounds underwater, and divers surrounding the ship confirm any echos. The divers are so skilled that they can identify objects simply from these sounds.
While Cricket did not directly participate in the operations of his peers, he was known to occasionally dive in the waters of Jaya in search of any evidence about Shandora. Cricket has knowledge about Noland's expeditions and discoveries since he had the latter's logbook in his possession.
Cricket arrived on the island of Jaya several years ago before the present storyline. The alliance got formed sometime after Cricket's own crew abandoned him for trying to prove whether or not his ancestor Noland was a liar and began the search for the lost City of Gold that had supposedly sunk into the ocean. Shortly afterwards, Masira and Shoujou appeared. They were fans of Noland's storybook, wanting to help Cricket find the city. The alliance was then officially formed.
Sky Island Saga
The Straw Hats first encountered Masira when he tried to salvage a ship that fell from the sky, they later met Shoujou while traveling to Cricket's house, coming into conflict both times. However, after saving Cricket's life from a disease, they became friends. The Saruyama Alliance helped the Straw Hats begin their journey to Sky Island. However, while the Straw Hats were in Jaya's forest looking for a "South Bird", the Bellamy Pirates attacked, stealing their gold artifacts that acted as their only proof that the city existed. Angered, Luffy defeated Bellamy and returned the gold to Cricket, before they set off for the sky.
At the end of the Skypiea Arc, Luffy rang the golden bell of Shandora, signaling, among many other things, that the City of Gold existed. With one dream resolved, the Saruyama Alliance decided to move on to another.
From the Decks of the World
