In the distant future of 2063, a group of students from Caird High School, accompanied by a young child, set out on an interstellar camping trip to MCPA, a planet far from Earth. Among the travelers are the courageous Kanata Hoshijima and the cheerful Aries Spring. Upon their arrival, a peculiar luminous orb pursues them, leading to a perilous journey that transports them 5,012 light-years away from their intended destination. Stranded and resource-depleted, their only hope lies in an abandoned spacecraft nearby, sparking a desperate struggle for survival and the gradual unraveling of the grim secrets shrouding their ill-fated adventure.
