Jitsuryokuha Elite Jin

Creatures from another dimension have invaded Earth. Humanity's weapons prove useless against these beings, known as "Neighbors," so scientists have developed new arms based on the enemy's own technology. Wielding these weapons, humans struggle to defend themselves against the invaders. The head of the central base has dispatched ace soldier Yuuichi Jin to aid the failing Base 7 and rescue his own son, Yuiga Tadashi, who serves as the base's leader. There is just one problem: Tadashi himself is the reason Base 7 is failing. A dreadful leader who cares for nothing but his own reputation, he believes that being the central base leader's son entitles him to act however he pleases. Will Jin be able to set this terrible situation right?
