The world seems to have lost all hope with the abrupt arrival of aliens. The Special Counter-Aliens Task Force, consisting of the anonymous director, the ruthless Shiro, and the easygoing Arikawa, is the planet's last line of defense. The Task Force's luck changes for the better when Arikawa discovers a young boy stranded on a hill. This boy, Kakashi, has exceptional powers that could potentially defeat the aliens, resulting in humanity's ultimate salvation. Nonetheless, Kakashi suffers from amnesia and lacks knowledge of how to utilize his capabilities. His only hope is to rely on Arikawa, Shiro, and his flawed cellphone, which could reveal vital information about his past. However, Kakashi faces numerous obstacles such as grappling with doubts and intense emotions that impede his progress and raise doubts about his intentions. Can he conquer these inner conflicts and apprehensions to become the planet's savior?
