Appearance

Each of the five brothers is a perfect copy of Ipponmatsu, so much so that the game simply recycles his character portrait for all of them. They are short, tan-skinned men whose black hair fans out toward the sides of their heads, with red noses, the only notable change being the green shirts they wear in place of his blue one.

Personality

The siblings are compulsive stamp-givers, pressing a stamp on anyone they run into whether or not it was asked for. When that person already holds at least one stamp from another brother, they follow up with a reward.

History

Within One Piece: Treasure Wars, the brothers number five in all, named Nihonmatsu, Sanbonmatsu, Yonhonmatsu, Gohonmatsu, and Ropponmatsu. A player meets them by landing on a particular square on each of the Cream Mist island maps, with one stationed on every island: Nihonmatsu on Malti Island, Sanbonmatsu on Sorbi Island, Yonhonmatsu on Oligo Island, Gohonmatsu on Xyli Island, and Ropponmatsu on Granu Island. Finding a single brother yields a stamp, while collecting two or more earns the player a Jolly Roger item or an attack boost for that map. Their names extend the wordplay of Ipponmatsu's own, counting upward from his ippon, meaning one point, through the words for two, three, four, five, and six points.
