Fish-Man District

Noah (ノア) is a region of Fishman Island known as the Fishman District (魚人街) and is notorious for being one of the tougher parts of the island. In the beginning, it was a giant institution for orphaned children. But eventually corruption infected the management and therefore the institution became a lawless district where the outcasts of Fishman Island gathered. The zone consists of a massive ark where fishmen live in and around. This is the base of the New Fishman Pirates. The district made its debut in Chapter 608.

Trivia

 * The district is most likely named after the story of Noah's arc.
