(U.C. 0079.04.26 - 0079.04.27) The Federation forces are routed in face of the onslaught of the Zeon Zakus during Earth Drop Operations. When the main forces are retreating for resupply, Lt. Ben Barberry, who leads an anti-mobile suit special tactical squad utilizing the "Regina" missile launcher, is ordered by his arrogant superior, Col. Michael Colmatta, to advance and ambush the pursuing Zeon forces. Unknown to others, Barberry, who loses every subordinate in the previous engagements, is frequently haunted by a spirit called Shinigami, who patrols the battlefield collecting souls of fallen warriors. Barberry and his platoon arrives at the outskirt of a ruined mining town and receives information of two Zakus (instead of three from the intelligence report) rampaging through a nearby supply depot. The ambush is set but failed to achieve an immediate kill when one of the squads opens fire prematurely.
