Keiichi-047

Keiichi-047 is a SPARTAN-II commando of the UNSC Naval Special Warfare Command. He served during the Harvest campaign in February 2531.

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.

Trivia
Keiichi's profile image on the Halo Wars website actually depicts Jerome-092 during the raid on the Apex site.
