During a break on his premiere tour for the smash-hit pop band Bad Luck, lead singer Shuichi Shindo comes home to spend some quality time with his boyfriend, Eiri Yuki, the famous romance novelist. However, he finds their apartment empty and the only thing waiting for him is a mysterious, alarming note. Has something horrible happened to his lover? Does it have any connection to that gorgeous lady who's been stalking the writer for the past few weeks? Based on the popular manga and anime, Gravitation: Voice of Temptation is a highly charged, hilarious story about two lovers drawn together despite the overwhelming odds.

Eiri Yuki
In his 20s. Handsome, popular romance novel by trade, Yuki is cynical and aloof in real life. He's inexplicably drawn to Shuichi's warmth and vitality, and the two begin a tumultuous love affair that scandalizes their fans and drives them both insane.

Hiroshi Nakano
Shuichi's best friend and the guitarist for Bad Luck. He's popular, handsome, and intelligent. Hiroshi loyally shepherds Shuichi through some very trying times.

K
Formerly the Chief Executive of the Secret Service turned Ryuichi Sakuma's over-zealous bodyguard, "K" is now Bad Luck's manager. An American modern-day cowboy with passion for guns and ninja movies, K can be quite a handful.

Ryuichi Sakuma
lead singer of the famous band, Nittle Grasper, Ryuichi is Shuichi's main idol, living the high life in LA. Carefully balancing between being supportive and competitive, Ryuichi helps to inspire Shuichi about the contest!

Sakano
Shy, sweet, prone to fainting spells and ulcers, he was formerly Tohma Seguichi's right hand man at N-G Records. Now he's Bad Luck's producer.

Shuichi Shindou
19 years old. Energetic, optimistic, often ridiculous, Shuichi is living his dream as the lead singer and lyricist of his band, Bad Luck. Despite his high-energy personality, Shuichi is extremely sensitive and lacks confidence.

Tohma Seguichi
The enigmatic young president of N-G Pro Records, he's also the lead keyboardist for the legendary Nittle Grasper and the manager of band Ask. He uses his friendship with his brother-in-law, Yuki, and his clout with pop star Ryuichi Sakuma to manipulate Shuichi into an amazing performance.
