Soushi Minashiro 皆城総士
Soushi Minashiro is basically the only one of the children on Tatsumiya Island who knows the truth-- the world has been under invasion by an alien race called the Festum for the past three decades and Japan was destroyed 28 years ago.
He is the son of Kouzou Minashiro, the commander of the secret military fortress Alvis, which is hidden in the bowels of the peaceful-seeming Tatsumiya Island. From a very young age, Soushi was bred to become the next commander of Alvis, so he has had a very isolated childhood carrying the heavy secret of the war and being told day in and day out that he must live only to protect the island.
Because of his incomplete vision, Soushi cannot pilot a Fafner and fight the Festum hand-to-hand. Instead, he acts as the battle commander who connects directly into the minds of all the Fafner pilots through a super computer called the Siegfried System, and directs them in battle. All the pilots, especially Kazuki, hold to him for strength and leadership-- a burden that he shoulders with grace and stoicism.
Because of his years of virtual isolation, he is rather awkward socially, (in fact, most people find him quite unapproachable or mistakenly think him hard-hearted). Kazuki alone seems to make efforts to understand and befriend him and the two become very close over the course of the series.
