Menma's death drove a group of childhood friends apart. Years later, her ghost brings them back together, forcing them to confront the pain and guilt that remain as they try to help her move on.
For Jinta Yadomi, the reunion begins during a summer spent skipping school and playing video games at home. When Meiko "Menma" Honma appears and insists that he grant a forgotten wish, he initially dismisses her presence as a hallucination brought on by the heat. But once he becomes convinced she really is Menma's ghost, he and their old friends must face the loss that separated them. Laying her spirit to rest also means returning to feelings they have yet to resolve.
