The world of One Piece is vast and full of interesting things. The power system, characters, and relationships of the characters are often difficult to keep track of, which is why Vivre Cards are useful, as they act as pages of information in a One Piece data book.
A One Piece leaker has shared Vivre Cards of the Straw Hat Pirates and several other characters. While the cards were originally written in Japanese, they have also been translated into English. Luffy has two Vivre Cards, one with his usual information and the other focusing on the Straw Hats' Gear 5 transformation.
Gear 5 was first hinted at in chapter 1044, titled “The Return of Joyboy”. In chapter 1045, Luffy took on a surprising form, causing shockwaves across the world as people were confused about his power. The Gorosei described it as “the world's most ridiculous power”. But to this day, there are still many mysteries surrounding Nika and Joyboy.
In addition to the usual information such as age, date of birth and height, the Vivre Card also records “Strange! Rhythm and laughter resound! 'Liberation Fighter' lights up 'Dawn'!”
Vivre Cards then describes the Liberation Drums as “unique heartbeat when 'GEAR 5' is activated”adding that it is “the music of a party that Luffy felt very familiar with”.
Before this information, a fan expressed that: “The fact that Luffy's heartbeat is literally the sound of a party makes me smile. He really is the life of the party.”
