Conscription
Keiichi-047 was a genetically, intellectually, and physically gifted child chosen for the SPARTAN-II project. He was abducted by the Office of Naval Intelligence and replaced with a flash clone when he was around six years old. He and seventy-four other children were taken to Reach in the Epsilon Eridani system. There, he was trained by the "dumb"AI, Déjà and Chief Petty Officer Franklin Mendez, with the two serving as the Spartans' teacher and drill instructor, respectively. In 2519, he was taken alongside his fellow trainees to a Military Wilderness Training Preserve for a mission that required each trainee to be left alone in the woods with a only a single piece of a map. It was up to them to find one another so that they could piece the map together and locate the designated extraction point. The mission was ultimately a success. At another point during training, Keiichi and the others traveled to Emerald Cove for an underwater mission. There, they abandoned Mendez and lived on their own on an island for a few days. By July 14, 2523, Keiichi and his fellow Spartan-IIs had begun facing the formidable and ruthless UNSC Marine Corps' Tango Company in simulated war games. On March 9, 2525, Keiichi and the rest of the Spartan-II candidates underwent their augmentation procedures at Medical Facility Endurance orbiting Reach. After successfully enduring the procedures, Keiichi later attended a military funeral aboard the carrier, the UNSC Atlas, in the Lambda Serpentis system for the Spartans who died during the process. Afterwards, they all returned to Reach for their final training phase in the Highland Mountains.

After the Covenant attack on Harvest and the beginning of the Human-Covenant War, Keiichi and the rest of the Spartan-IIs were brought to the Reach FLEETCOM Military Complex, where Rear Admiral Michael Stanforth and the AI, Beowulf, briefed them on the emerging Covenant threat. In response, the training of Keiichi and the rest of the Spartan-IIs was accelerated, and the Spartans were sent to Chi Ceti IV in the Chi Ceti system to receive their new MJOLNIR Powered Assault Armor from the Damascus Materials Testing Facility in order to aid in combat against the alien threat. While en route to Chi Ceti IV aboard the Paris-class heavy frigate, the, they were attacked by the Covenant warship, Unrelenting. The Commonwealth was able to ward off the Unrelenting and the Spartans were deployed to Chi Ceti IV with Halsey, where they each recieved a set of armor. While the Spartans were returning to the Commonwealth, the Unrelenting returned and engaged the frigate. To provide aid to the Commonwealth, John had Keiichi and the other Spartan-IIs use thruster packs to embark towards the Unrelenting so that they could destroy the warship with Anvil-II AS missiles, though only John, Kelly, and Sam made it aboard

Near the end of the campaign Keiichi aided the Marines of the during an engagement with a Covenant armored force near Harvest's northern pole. Keiichi charged the Covenant's position, killing several Sangheili and Unggoy with his AIE-486H machine gun. Upon reaching the Covenant's main line he hijacked a Wraith and used it against the remaining Covenant forces, quickly turning the tide of the skirmish in the UNSC's favor.

After the engagement he reported COM glitches due to the upgrades to his neural interface which Serina, Spirit of Fire's onboard artificial intelligence, had devised.

Keiichi had been listed as MIA as of March 3, 2558. Whether his MIA status is genuine or actually obscures his death per ONI Directive 930 is unclear.
