Kyoichi Motobuchi (元渕 恭一, Motobuchi Kyōichi) is a minor character in Battle Royale.


Nothing is known about Kyoichi's past. If Kyoichi was anything like his novel and manga counterparts, then his father would've been extremely important, making him think there was no way he could be selected for the program. He also would've been extremely studious. He was the male class representative. He wasn't as straight-laced as his novel and manga counterparts, as shown by him genuinely enjoying the class basketball game.

Friends and Enemies[]

None is known about Kyoichi's friends or enemies. He might've spent too much time studying to make friends.

Before the Program[]

Before Kitano resigned, Class B decided to take a day off and skip school, Kyoichi included; he attended the basketball game against Class A, and celebrated when Class B won. Kyoichi decided to go on the class trip; while on the bus, he most likely took a nap. Kyoichi fell asleep after breathing in a sleeping gas pumped into the bus; he was then transported to an island and fitted with an explosive collar.

Kyoichi, along with the rest of the class, woke up in a classroom in the island’s school. Unnerved by the presence of Shogo Kawada and Kazuo Kiriyama, Kyoichi rushed over to the window to watch a helicopter land in front of the school. Kyoichi was shocked to see that Kitano had returned. When Kitano asked the class if they knew the BR Act law, Kyoichi kept quiet, obviously knowing the law, but afraid to say it aloud. Kyoichi asked Kitano if he can go home if he wins, which Kitano responds that he can but only if everyone else is dead.

Kyoichi was horrified upon seeing Masao Hayashida's corpse. When Fumiyo Fujiyoshi was killed, Kyoichi panicked and ran for the door trying to escape before running towards the back of the classroom when the soldiers began firing. Kyoichi gets into a fight with Yoshitoki Kuninobu, resulting in his collar getting activated; he then ran around the room trying to evade him.


Kyoichi, moments before his death, after being shot by Shogo twice.

When Kyoichi's name was called, he grabbed his school bag and ran towards the front of the room; he caught his supply bag and ran out of the school.

During the Program[]

Kyoichi encounters Shuya Nanahara and Noriko Nakagawa when Shuya freaks out following the death of Tatsumichi Oki. Kyoichi shoots at the pair, but misses. He then starts mumbling a math equation and says he'll win and go to a good school. He tries to shoot them again, and again his shots goes wide. Suddenly, he is shot in the arm by Shogo Kawada, who cocks his gun threateningly. Kyoichi flies into a rage, attempting to run at Shogo, but the transfer student guns him down with a single shotgun blast to the stomach. Kawada then takes his gun.
