One Piece Odyssee

The library, comprising the lower level of the hut-like structure in the stern of the Thousand Sunny, is a large circular room with numerous bookshelves and windows and a bench encircling the whole room. Everyone but Luffy has books stored here. In the middle of the room is Nami's mapping desk, which contains the Ship's Log, among other things. Toward the port side is a ladder leading up to the bath. The library, according to Nami, is "the brain of the Sunny."
