Yui, Iori, Himeko, Taichi, and Aoki choose to join the Student Cultural Society; they begin to get to know each other a little too well after swapping bodies.

The Student Cultural Society experiences problems of an out-of-body sort; the group is at a loss until a mysterious figure explains things.

As the body switching becomes more common place, the Student Cultural Society members become more adventurous with it.

Inaban is not well, and she has been hiding it from the group; Taichi feels her physical pain and is determined to help her.

Heartseed grows bored with the group, takes over Iori's body, and jumps off a bridge.

After weeks of blissful silence, the members of the group start hearing voices, and their peace is once again shattered.
