Sora yori mo Aoi Sekai de

In the distant future, there exists a world where everything unnecessary has been stripped away to the extreme. Where labor, illness, reproduction, and crime do not exist. The only real obligation is a game of “tag” where people split into two teams fight for survival. In such a world, Kokoro spent his days repeating the bare minimum of daily life. That day was supposed to be just like any other. He would attend class, play a round of tag, meet up with his friends at a café afterward, and then go home. And that would be the end of it. However— “How long are you gonna keep sleeping?” Beneath an unnaturally blue sky, an unfamiliar man is pointing a weapon at Kokoro. From that moment on, the monotonous repetition of his bare minimum routine came to an end.
