|Performance(Class 3-C in Kobe)|
|Killed by:||Shogo Kawada|
|Cause of Death:||Shot|
Keiko Onuki was a student from Kobe, and was the primary love interest of Shogo Kawada. She plays a small, but nonetheless important role in the film.
Nothing is known of Keiko's back story, except that she was a student in Class 3-C at Kobe Junior High School, the same as Shogo Kawada. She was a participant in the Program that took place 3 years prior to that which the film is centred around. She was also, apparently, at least a close friend of Shogo for some time prior to their participation in the program.
Her only known performance in The BR Program was that she survived for the first 2 days by staying with Shogo Kawada, who protected her (He apparently went as far as killing his best friend to keep her safe).
On the last day of the program in which she took part, she was one of two students left (the other, obviously, was Shogo Kawada). As time limit approached, both students heard their collars emitting an alarm, signaling that they only had seconds left before the collars would explode and kill them. Upon realizing this, Shogo and Keiko look into each other's eyes before hugging.
Before the collars can explode, she pulls out a handgun and shoots Shogo in the stomach, in an attempt to kill him and thereby save her own life. However, this shot fails to kill him and he rolls down a slope before impulsively turning and shooting her twice. She rolls down the slope , and lands near Shogo. Shogo crawls to her and attempts to revive her. She briefly awakens, smiles at Shogo says "Thank You" and dies in his arms.
This ends this game, with Shogo Kawada as the winner, and Keiko Onuki in 2nd place. The names and positions of the other students are unknown.
*Shogo keeps a photograph of taken of himself and her in his wallet.
- At the beginning of the game in the Film, Shogo vows to find out what her last smile meant to him. In the end, thanks to Noriko Nakagawa , he eventually does find out what the smile meant. He has also continued to ponder her last words since she died.
- It is worth noting that even after she shoots him, Shogo bears no anger toward Keiko . This swift forgiveness may show the strength of his feelings for her, as may his prompt attempts to revive her.
