アブソリュートキル

The small, isolated island of Tufa straddles two countries and has two schools, one on each side. The students enjoy a peaceful school life, until the two countries enter a state of war. The two schools become enemies, as their students fight and kill each other…! A tragedy born from childish ignorance… A relentless story of adolescent survival! (Source: Nihonbungeisha, translated)
