Yumiko Kusaka (日下 友美子, Kusaka Yumiko) is a minor character in Battle Royale.


Yukiko and Yumiko are said to make the same mistakes and make identical creations such as cakes. In Ms. Takata's home economics class in the fourth grade in primary school, the two almost make identical hard-boiled egg creations; Yumiko had brighter yolks as she spent less time hard-boiling the eggs. Yumiko was more tomboyish than Yukiko, wearing pants and shorts compared to the latter dresses in the flashbacks.

Friends and Enemies[]

Yumiko was best friend with Yukiko Kitano.

In the Program[]

Yumiko meets with Yukiko after leaving the school (due to the fact Boy #7 Yoshitoki Kuninobu had died before the program started, Yumiko is the next person out after Yukiko), and the two make their way to the former tourist information center on the eastern slopes of the north mountain. The two girls chat and discuss who they have crushes on, and realize that they cantt bear killing each other. Thinking that many of their classmates must feel the same, they make an announcement over a megaphone, calling for their classmates to meet them and discuss things as a group. The announcements alert Kazuo Kiriyama to their location. Kazuo creeps up on them and shoots both of them with his machine gun. He then finishes off Yukiko with a gunshot to the head with Yumiko being shot immediately afterwards. Kazuo would take Yumiko's grenades and use them when trying to kill Shuya Nanahara, Noriko Nakagawa, and Shogo Kawada.
