Shuichi Shindo Voiced by: Tomokazu Seki (Japanese);
Rich McNanna (English) is the primary protagonist of the series. Shuichi's ambition at the start of the series was to follow in the footsteps of his idol, Ryuichi Sakuma, the lead singer of the band Nittle Grasper, by creating his own successful music band named Bad Luck. He has pink hair. One day when, as he is walking through a park reading his lyrics of the song "Glaring Dream", a sudden breeze blows them away, where they are picked up by a mysterious man who dismisses them as "elementary-level", saying that Shuichi has zero talent and should just give up. Stung by the man's criticism, Shuichi becomes determined to make him apologize. Shortly after his friend Hiroshi Nakano helps him realize that he is attracted to the man in the park, Shuichi sees an interview on television that shows that the person in the park is in fact, the famous romance novelist Eiri Yuki. Initially, Yuki treats Shuichi coldly, but Shuichi perseveres through Yuki's icy demeanor and eventually the two begin a relationship. Shuichi's band also begins to rise in fame, and a major portion of the series focuses on his attempts to balance the demands of his job with his pursuit of Yuki's affections.
Eiri Yuki Voiced by: Kazuhiko Inoue (Japanese); Jim J. Ward (English, as Rome Elliot) is a popular romance novelist who met Shuichi Shindo in the park and mercilessly dismissed his song lyrics. Through coincidence, they kept bumping into each other, and eventually came together romantically. In the series (manga and anime), Eiri and Shuichi struggle with their celebrity status and their mercurial relationship. Eiri's father is a monk, who runs a temple in Kyoto. He has one younger brother, Tatsuha Uesugi, who is a monk-in-training. He also has one elder sister, Mika Uesugi, who is married to Tohma Seguchi. At the beginning of the series, Eiri is engaged to
Ayaka Usami. In the Gravitation EX first book, Eiri is temporarily, according to himself, blinded. It is unknown whether or not his eyes will heal. He did it to save Riku Kitazawa (his deceased past mentor Yuki Kitazawa's orphaned child) from being run over by a semi-truck, which is unlike his original character. Later, Eiri and Shuichi find that Yoshiki Kitazawa (Yuki Kitazawa's trans sister) had dumped Riku off on them to parent, possibly just until she returns. It turns out in track 76 that Eiri was faking his blindness, though the reason is unknown.
Tohma Seguchi Voiced by: Ai Orikasa (Japanese);
Bill Rogers (English) is the keyboard player in Nittle Grasper and Mika Seguchi's husband. He is the head of N-G recording company and demands the best from all his contractual bands. Tohma is very protective of Eiri Yuki, and blames himself for the trauma Eiri suffered as a teenager, seeing that he was the one who hired Yuki Kitazawa in the first place. He has declared Eiri as his dearest. He is unfailingly polite to the point where he will refer to anybody (including his wife) as -san, and appears to be a friendly and even-tempered person (if also a ruthless businessman). As the series goes on, it becomes evident that much of this is a carefully constructed mask: when Eiri is involved, Tohma has been known to be far from rational and soft-spoken. Tohma is an anime-adaptation of
