The year is 1983. The Cold War is in full effect, and humanity is under attack. Strange aliens, given the name "BETA," have descended to Earth with the goal of destroying all life. Soldiers have been tasked with piloting large combat suits called Tactical Surface Fighters (TSF) to repel the alien invaders, but the front line is slowly being pushed back towards the surviving cities. Schwarzesmarken follows the story of Second Lieutenant Theodor Eberbach and the other members of the 666th TSF squadron, a ruthless unit that values a mission's completion over human life. Stationed in East Germany and led by war hero Captain Irisdina Bernhard, the unit specializes in counterassault attacks on laser-class BETA. But the 666th squadron finds itself with more enemies than just the alien forces when optimistic rookie Katia Waldheim joins the squadron, drawing the attention of East Germany's secret police, the Stasi.

After the noble Kappa Kingdom falls to the Otter Empire, the Kappa prince Keppi loses much of his power and becomes helpless against the unseen Kapa-zombies. These zombies plague the world, and are the creations of the Otters and manifestations of people's deepest desires. With no other choice, Keppi must rely on three young boys: Kazuki Yasaka, who must carry a box with him wherever he goes; Enta Jinnai, Kazuki's childhood friend; and Tooi Kuji, a delinquent and a school truant. By having the mythical organ called a shirikodama removed from them, the boys are able to become Kappa themselves and fight the Kapa-zombies. However, to defeat them, the boys must connect with each other via their minds, bodies, and—most importantly—secrets. As the Kappa Kingdom relies on these boys, they must reveal themselves as they have never done before, all the while learning that connections are fragile and truly precious things.
