More than a month after Emergence Day, Ozaba and two other members of Kilo Squad, Pvt. Damon Baird and Pvt. Augustus Cole, were on an evening patrol with several other Gears in Halvo Bay's Old Town, which had been evacuated. An hour into the deployment, noises could be heard on the rooftops, which Ozaba dismissed, believing them to not be caused by Locust. A Sniper situated on the rooftop then opened fired on Ozaba, shooting him in the head, killing him. Cole provided covering fire for Baird as he ran to Ozaba. After realizing he was dead, Baird lifted his body over his shoulder and ran back to cover near Cole, who, alongside Baird and the other Gears, managed to push back the Locust. After the skirmish, Col. Ezra Loomis arrived and heard Cole's account of the event. After collecting Ozaba's COG Tags, Loomis told Baird that he would oversee his promotion to Lieutenant in his former CO's place.
