Nineteen years after Ryoma Nagare, Go Ichimonji and Messiah Tyr left Earth in the Shin Getter 1 to Mars, the world is recovering from a previous conflict that almost changed the planet forever. Upon that time, the conflict between Earth and an unknown entity known as the Andromeda Stellaration is escalating as swarms of technorganic insect-like aliens almost brought the planet to its knees. However the Saotome Institute, now under the command of Hayato Jin, is doing its best to repel the enemy while training new pilots for protecting Earth against extraterrestrial threats both from within and beyond the planet. All for to pilot a new Getter unit meant as the final legacy of Professor Saotome: Getter Robo Arc.
In the midst of the conflict, Takuma Nagare, a teenage boy and the only son of Ryoma is searching for answers about his own legacy guided by his friend Baku Yamagishi. During a battle between a metal beast and the Saotome Institute's Getter Team, Takuma and Baku hijacked a fallen Getter D2 after its pilot has died. Much to the dismay and curiosity of Hayato, he sent the Getter Arc piloted by Sho Kamui to assist Takuma on defeating the metal beast and was brought in to the institute. Seeing Takuma and Baku's potentials, Hayato assigned both alongside Sho to operate Getter Robo Arc as humanity's last hope against the Andromeda Stellaration to protect humanity from its own extinction.
