Mr. Kiriyama (full name unknown) is a minor character in Battle Royale.
Backstory[]
Mr. Kiriyama was the father of Kazuo Kiriyama. As soon as he was born, Kazuo could remember that his father and mother were always happy. He enjoyed spending time with his son as they watched the Action Rangers and told his son that he could be a hero as well as the chosen one.
One night would change everything. Mr. Kiriyama would lose both his wife and son as they were hit by a sleeping truck driver. His wife lost her life while his son lost his emotions. He took Kazuo to the doctor but all they could figure out was that Kazuo had brain damage and cerebral trauma. There wasn't anything they could do for his son. He was most likely upset when he learned his son's class was selected for the Program.
