May 1, 1945 ― Germany. On the eve of Berlin’s collapse, a group of men and women carried out a certain ritual. To them, suffering defeat in the war meant nothing.

Following the war, they faded from sight, mind, and eventually into the realm of myth.

Ren Fujii, a young man attending high school in Suwahara City, finds his friendship with his old buddy Shirou Yusa shatter to pieces following a certain incident, ending in a vicious fight that sees Ren hospitalized for two months.
