Kazuo Kiriyama was a ninth grader in a totalitarian Japan where the government instituted a law known as the BR or Battle Royale Act, which states that a randomly selected class of ninth grade students would be sent a remote island, armed with random weapons (anything from an Uzi to a paper fan), and made to kill each other until only one survives. The students are given bomb-collars which will detonate if the attempt to escape, remove the bomb, enter a forbidden "danger zone" The reasoning for this varies between the novel, manga, and film version of the story. In the novel and manga, the act of an alternate totalitarian Japan known as the Republic of East Asia, possibly as an act of retaliation against youth protests or to use the survivors for some sort of military unit (implying the WWII either ended in Axis victory or never happened). In the film, the BR Act is a government retaliation against youth opposition during a period of high unemployment and social unrest.

In either case, Kiriyama's backstory is similar. Kiriyama is a sociopath who suffered from brain damage as a child that made him unable to sympathise or empathize with anyone, and gave him a violent demeanor. Kiriyama volunteers to take part in the Battle Royale for his own amusement. Kiriyama is initially armed with a paper fan (or a moderately more useful tessen war fan in the manga), but manages trick another student in to thinking he is going the ally with him, then disarms him with his bare hands and uses the contestants Uzi to kill him and several others. Kiriyama takes their weapons, arming himself with a a handgun (the model varies between the manga, novel, and film, a wakizashi, two Mk II Fragmentation Grenades. Kiriyama then goes on to kill several others, including two girls who draw attention to themselves attempt to contact the main character and ally themselves with him, a girl named Mitsuko Souma, who is every bit as sociopathic as he is, and a boy who he kills in a particularly gruesome manner, decapitating him with his wakizashi and then placing a grenade in his severed head and throwing it at Shuya Nanahara, Noriko Nakagawa, and Shogo Kawada, the three protagonists of the series. Nanahara and the others escape. Nanahara, Nakagawa, and Kawada confront Kiriyama a final time at the scene his latest murders, a building consumed in flames by the untimely explosion of a car bomb, which Kiriyama's victims intended to use to destroy the building on the island used as a forward base by the government forces in charge of the Battle Royale event. In the film, manga, and novel versions, Kiriyama is finally killed by a different person. In the film, he is killed Shoga Kawada, who shoots him with a SPAS-12 assault shotgun. He is shot with a pistol by Shuya Nanahara in the manga, and shot with a revolver by Noriko Nakagawa in the novel.

Battle vs. Yukiteru Amano (by SPARTAN 119)Edit

Okishima Island, Japan, an alternate universe where Yukiteru is involved in the BR program.

Kazuo Kiriyama walked down a street on the abandoned island of Okishima, Japan, location of the Battle Royale Program's event, Uzi in his hands. Kiriyama reloads his Uzi, topping off the magazine from at ammuntion spent killing his previous victims.

Yukiteru Amano runs across the road, MP5 in hand. Kiriyama fires a burst from his Uzi at him missing. Yuki returns fire, forcing Kiriyama to take cover behind a chest-high brick wall. Yuki then retreated into a house.

Kiriyama readied an Mk II fragmentation grenade and tossed it into the building. The grenade exploded inside the house, blowing out the windows and spraying sharpnel everywhere. Kiriyama got up, Uzi at the ready, and entered, but Yuki's body was no where to be found.

Yukiteru Amano stood on the top of the stair and fired a short burst at the exact location where Kiriyama was second before he moved to check the kitchen. Kiriyama immediately turned around an fired back, one of the round's hitting Yuki's shoulder, causing him to drop the gun.

Yuki threw a flashbang grenade down the stairs, which landed at Kiriyama's feet. Kiriyama rolled into the kitchen and plugged his ears and closed his eyes, lessening the effects of the grenade, but still causing a loud ringing in his ears. Worse still, as he rolled, he had dropped his Uzi.

Kazuo saw Yuki climb down the stairs and fire three shots from his SiG Sauer. Kiriyama dove out the kitchen window, into the backyard to avoid more fire, then drew his Walther and fired several shots at Yuki. After exchanging fire for a few minute with no hits, Yuki drew his machete and exited the abandoned house, into the backyard.

Kiriyama unsheathed his wakizashi in response, and blocked a blow from Yuki's machete, before striking back himself. Yuki raised his machete for a downward strike, however, Kazuo dodged and stabbed him with his wakizashi.

Yukiteru fell to the ground, greviously wounded and screaming the pain. Kazuo got out another Mk II grenade and placed it next to Yukiteru, before jumping back into the kitchen and hitting floor. Kazuo heard a loud bang as his opponent was blown apart. Kazuo retrieved his Walther and Uzi, as well as Yuki's MP5 and SiG and, after reloading all of the weapons, exited the house to hunt down his next victim.

WINNER: Kazuo Kiriyama
