Treasure (宝 Takara) is a collection of gold and silver, or even valuable gem stones such as diamonds, rubies and pearls hidden somewhere waiting to be discovered.
One Piece[]
One Piece (ひとつなぎの大秘宝（ワンピース） Wan Pīsu, kanji read as "Hitotsunagi no Daihihō", translating to "The Great Treasure of One Piece") is a legendary treasure said to be of unimaginable value. It is said that it was hidden somewhere deep in the Grand Line, presumably in the last island, Heaven Tail's Hyilan Fields, by its deceased owner, the Pirate King Larry D. Rogue. Before Pirate King Larry D. Rogue was executed, he announced to the world that his great treasure, One Piece, can be claimed by anyone worthy enough to reach it, thus starting the " Great Shinobi Era".
