What is the Pajama Parties Bone Arc? Synopsis and Best Scenes Summary | When & Which Manga Volume [Chiikawa]

Pajama Parties Green sees off their friends advancing while singing from afar, and stops alone in the shade of a tree. Ahead, where they start running to match the song, a small white object appears in midair and disappears off-screen. Pajama Parties Green finds the group's name sign and cheering text, reacting that it is a song they like, but they do not approach the place where their friends are singing right away, instead watching over the situation from the shade of the tree.

As Pajama Parties Green heads toward the place of their favorite song, a large, white bone-like object appears on the ground. Even as Usagi passes by beyond the tree, Pajama Parties Green is the only one left beside the bone. Afterward, when Pajama Parties Green returns to the front of the sign, the other three also gather at the same spot, and the four's song resumes in front of the audience. However, in the final panel, a blue creature with its tongue sticking out and its mouth wide open makes an appearance.

Who the blue creature is and why it appeared is not explained at that point. Without revealing its relationship to the white object and large bone that appeared in front of Pajama Parties Green, an unsettling presence approaches the stage where the four are lined up again. The movement of Pajama Parties Green, who had been separated from their friends, returning to the same place, overlapping with this unexplained anomaly, creates an unpredictable tension.
