With the A.E.G.I.S. base destroyed and the gate robot disabled, Shun and his allies face overwhelming odds against Shadow. The New York Headquarters has ordered the abandonment of the Far-East Branch, hoping its sacrifice will stop further destruction. Seeking refuge, the group retreats to Shun’s father’s workshop, the only location capable of repairing the gate robot. However, without a functioning gate engine, the machine remains useless. During this desperate time, a startling discovery forces Shun to investigate the circumstances surrounding his father’s death. Uncovering the truth about his past becomes crucial, potentially offering the only hope for the Gate Keepers to defeat their enemy.
