Jet Set Radio

Gum (ガム, Gamu) is a 17 year-old Rudie living in Tokyo-to. She is the one of the main playable characters and overall deuteragonist in the Jet Set Radio series. She, alongside Corn and Beat, is an original member of the GG's, along with being a loyal friend to her allies.

Gum has a counterpart in Jet Set Radio Future.


Gum wears a light grey sundress over a long-sleeved green striped top. Her name is displayed in green Japanese katakana (ガム) horizontally across her chest and on her skates. She wears light cool grey gloves with an orange four-pointed star emblem on them. She also wears a dark grey helmet with a white stripe down the middle, orange dots resembling eyes on the back and front, and the four-pointed star emblem encased in white on the 'ears'. Her blonde hair pokes out from the front, curling under her eyes along her cheekbones, and out the back down her neck. Her rollerblades are dark and light grey with yellow wheels and green detailing.

In game, she has no katakana on the front of her dress and instead has her Japanese name (ガム) spelled sideways in green down the back. Additionally, she has red thrusters on her skates and she wears a gray wrist device on her left arm.

Some official art depicts her with green katakana spelling her name (ガム) tattooed on the front or inside of her left thigh.

Gum is described as a perverse character who likes chewing gum. Her high Graffiti stat implies a natural affinity for art. Her willingness to show Beat the game's controls implies she is quite friendly.

She is an upbeat, cocky, sarcastic, and charismatic teenager who has a talent for graffiti art. She is very loyal and will treat her allies and friends with the upmost respect. On the other hand, Gum is considered to be a fugitive criminal, due to her crimes of repetitive harassment, vandalism, destruction of both public and private property, and reckless endangerment. Gum also enjoys art and roller skating when she gets the chance. Unlike Corn and Beat, Gum is more restless and self-determined.

Role in Jet Set Radio

At the beginning of the game in Shibuya-Cho's Bus Terminal, Gum first gives a series of challenges for Beat to complete in order to teach him the ways of the street and test his skills. After completing them, she deems him "not bad" and agrees to join his newfound gang, the GG's. She hangs around the steps leading to the car near Piranha and Slate in the Garage when not being played as.

At the start of Chapter 2 in the International versions, she gives Cube a challenge to prove she is worthy of joining the GG's. When Cube explains the situation regarding Coin to Gum, she responds that she has no idea who that is.

In the Jet Crush race for Kogane-cho, Gum is the chosen CPU competitor.

Other Appearances

Sega Superstars Tennis

Gum is a playable character in this Sega crossover tennis game. Her design is taken from the original Jet Set Radio. Gum's Superstar move has Tokyo-to's Police Force storm in on the tennis court, running over her opponent.

Sonic & All-Stars Racing Transformed

Main article: Gum (SEGA Superstars wiki)

Gum is a playable character in this sequel to Sonic and Sega All-Stars Racing, alongside Beat. She has a green and white bike similar to Beat's one. Her All-Star move makes a broken heart appear behind her. This could be a reference to the description of her, said during her introduction in Jet Set Radio Future by Dr. Professor K. In this game, she has a green tattoo on the left leg, saying "Gum" in Japanese, which is in reference to the same tattoo that is shown in her original Jet Set Radio appearance, though the tattoo was originally placed closer to her inner thigh. Sumo Digital most likely moved the tattoo to avoid making Gum seem overly sexualized. Her All-Star theme is a remix of Let Mom Sleep.

Gum also appears on an unlockable sticker in this game, obtained for winning an event in the Shibuya Downtown stage while playing as her.

SEGA Heroes

Gum appeared as a playable rare green hero in the canceled mobile game, SEGA Heroes. She was released to the game on October 15th, 2018 and was featured on the Beyondering selection, and on the main menu heading in 2018 and early 2019.
