All hope appears shattered when the planet is abruptly besieged by extraterrestrials. Earth's sole safeguard is a compact trio called the Special Counter-Aliens Task Force, made up of an unnamed leader, the domineering Shiro, and the laid‑back Arikawa in the face of imminent danger. Fortune shifts for the Task Force when Arikawa discovers a lone adolescent perched on a ridge. The youth, Kakashi, embodies humanity's final salvation—he possesses an unknown power capable of vanquishing the invaders! to defeat them. Yet, lacking memories and instruction on wielding his gift, Kakashi clings to Arikawa and Shiro while holding onto the sole fragment of his former existence: a shattered mobile that once belonged to his family. Kakashi wrestles with anxieties and emotions that obscure his thoughts, forcing him to question his own purpose. Can he surmount these doubts and internal battles to rescue the planet?
