Ep. 1: Kei Kurono and Masaru Katou die saving a drunk homeless man from a subway train.

1

Kei Kurono, an apathetic and self-centered teenager, encounters his old childhood friend Masaru Katou while heading home. They attempt to rescue a homeless man who has fallen onto the subway tracks while intoxicated. Both men are killed by an oncoming express train and awaken in a room containing a black globe alongside other recent deceased individuals: a school teacher, a dog, a politician, a long-haired blond man, two Yakuza gang members, and a mysterious eighth-grader named Nishi. Shortly after their arrival, a naked young girl is teleported into the room and faces attempted rape by one of the Yakuza members until Katou intervenes to stop the assault.
