Soushi is a child of the Alvis Project. Although he can't pilot
Fafners, he is a good tactician and he uses a super-computer named the
Siegfried System and is also the only child in Tatsumiya Island who has seen
outside world. Soushi was bred to be the next commander of Alvis, resulting in an isolated childhood while carrying the truth of the
outside world. With a great love for Tatsumiya Island, his
only wish is to protect it. As a socially awkward boy, Soushi is often
misunderstood as heartless.
