The story surrounds an aspiring singer, Shuichi Shindou, and his band, Bad Luck (formed with his best friend Hiroshi Nakano, who is on guitar). Shuichi wants to become Japan's next big star, and follow in the footsteps of the famous idol Ryuichi Sakuma, lead singer of the now-disbanded legendary group Nittle Grasper. One evening, Shuichi is looking over lyrics for a song he is writing when his paper is blown away by the wind and picked up by a tall, blond-haired (light brown in the manga) stranger. The man dismisses Shuichi's hard work as garbage, which hurts Shuichi deeply. Despite his anger, he is intrigued by the stranger. This will be their first encounter as Shuichi becomes fascinated by the stranger, who soon turns out to be the famous romance novelist Eiri Yuki (real name: Uesugi). Both the manga and the anime follow this plot.

The story picks up directly after volume 12; Shuichi and Eiri find and agree to momentarily take care of Yuki Kitazawa's son, Riku. Shuichi kisses and conducts a short affair with Ryuichi Sakuma, who announces that he has always been in love with Shuichi. Eiri is in a car accident that causes him to temporarily lose his eyesight, and Reiji announces that she's making a movie about everything that has happened to them. Shuichi believes that this movie is the reason Ryuichi "pretended" to go after him, although Ryuichi's true motives remain unknown.

The precursor to the Gravitation manga was a dōjinshi series titled Help!, which followed a similar storyline but cast the characters in slightly different roles. Murakami went to New York to research for a storyline later in Gravitation where the characters visit the city. Murakami has created dōjinshi based on Gravitation which she describes as "pretty hard-core, adult stuff. Remix is softcore and Megamix is much more hardcore". She created the dōjinshi to explore tensions between the characters. Murakami penned a thirteen-volume dōjinshi series called Gravitation Remix under the group Crocodile Ave. The dōjinshi are much more sexually explicit than the anime and deviate heavily from the manga storyline. Fans have requested that Tokyopop license Gravitation Remix, but Tokyopop regards the depiction of some characters to be too young and is concerned about themes of incest, and therefore has not licensed them. In addition to the remixes, Murakami created four highly sexually explicit "Megamix" dōjinshi, dubbed Mega-gra, Megamix: Panda, Megamix: Kumagorou, and Megamix: Capybara. These also deviate from the storyline as the Remixes do, with Panda including shota content. A new Megamix is currently in the works, entitled Megamix Zebra. Megamix Zebra will feature Shuichi, Ryuichi, and Eiri in a threesome, with Shuichi as the seme.

Written and illustrated by Maki Murakami, the manga was serialized in Gentosha's Kimi to Boku magazine between 1996 and 2002.

Tokyopop also released the series in six compilation volumes in 2009–10. Madman Entertainment distributes the series in New Zealand and Australia.
