Miss Goldenweek (Miss April Fools Day in the English dub) is an officer agent of Baroque Works, her partner is Mr. 3. Her personality is that of one laid back to the point of fault, she for instance is perfectly fine with having a picnic during an ongoing battle. Goldenweek's power derives from influential powers of color rather than any Devil Fruit, she paints a little symbol on others or inanimate objects in order to influence their behavior with it. After the initial uncovering and subsequent flight of Princess Vivi from the organization, Crocodile sends Goldenweek and Mr. 3 to lie in wait for Vivi and her Straw Hat escorts on the island of Little Garden. Goldenweek barely participates in the battles that follow aside from a brief stint of influencing Luffy's behavior with her paint. She is eventually chased off by Carue.

Recently in the series, Miss Goldenweek has gotten her own mini-arc on the chapter covers of the manga during the Water 7 arc. Where upon finding out that Baroque Works has been exposed after the Alabasta arc; she, along with Mr. 5 and Miss Valentine, fly from Little Garden on top of a pterodactyl with the help of a Color Trap to go visit them in jail. However, the symbol is washed away in a storm and the three are dropped onto a resort island where Hina, Jango, Ironfist Fullbody and their Marine unit happen to be vacationing. She manages to break out the other agents (except for Crocodile and Mr. 1) and starts a new Spiders Cafe with the ones that escaped.

Her name, "Goldenweek", comes from a series of national holidays in Japan known as Golden Week, similar to Spring Break in the United States.

Abilities
Miss Goldenweek works with a ability called "Colors Trap". Through the use of colors and a certain symbol, she is able to influence a person and make them do what she wants them to do. As demonstrated on Luffy, his simple mind was easily influenced by her colors trap.

Trivia

 * When she used the Rainbow Color Trap on herself, it was revealed that she wanted to become a true artist, complete with a beret and mustache.
 * Her character is essentially cut from the English dub since all of Little Garden itself was cut. Though she still is mentioned during Vivi's Baroque Works debriefing, and is still featured in the localized Grand Battle video game.
 * Due to her painting skills, many readers and fans alike believe that Miss Goldenweek may have eaten a Devil Fruit of some sort. Oda however explained in the SBS that she merely a type of a hypnotist that uses colors as a manner of suggestion.
