CROSS†CHANNEL

Gunjo Academy is a facility designed to gather and isolate those students who got a high score on an adaptation exam (scoring high on this exam indicates that the student is less likely to be able to be adapted to the society) mandated by the government. After a failed summer vacation with other members of the school's broadcasting club, Kurosu Taichi and some of the other club members return to the city, only to find that the world had completely changed. [Edited from Wikipedia]

Summer has come. With summer comes a long vacation from school. The Broadcasting Club has been torn apart, left to slowly disintegrate. Since returning from their first field trip of the summer, there's been a palpable distance between the club members. Now, only one single member continues to participate in the club activities. But a horrible realization has dawned on all of them: their school has been completely deserted. Are they really the only people left? The hero of our story is a member of the Broadcasting Club. He casually greets his friends as they show up at the otherwise deserted school. On the rooftop, we find club president Misato Miyasumi assembling a massive broadcast antenna, alone. This antenna was the club's summer project, and its completion for the purpose of sending a broadcast out to find other possible survivors has been their main goal. Last summer, the club comprised a close-knit group of friends who worked together. Yet now, only a single member continues their efforts. A group of the former friends watch her work, a cold glint in their eyes. This is the story of their clashing differences rising to a boil, and the resolutions that arise from these clashes. Once divided, the club members slowly begin to grow closer once again...
