Gravitation has also been adapted into a two-episode OVA series in 1999 directed by Shinichi Watanabe and a thirteen-episode TV anime series directed by Bob Shirohata. The TV series aired in Japan from October 4, 2000 to January 10, 2001, on WOWOW Wednesdays at 18:30 and was reaired on Tokyo MX in 2007. The anime goes to roughly volume 7 of the manga.

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 was 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.
