Could you kill your best friend?

In the future, the Japanese government captures a class of ninth-grade students and forces them to kill each other under the revolutionary "Battle Royale" act.
Battle Royale keeps every mind human — it fights its subject at zero distance. The story fights on E8/E10 of the E0–E14 reality ladder, compressing authority, control, survival, rebellion, youth.
Films fighting at the same level of reality, about the same things.
The same preoccupations examined at another scale — one mind versus a nation.
