Gosterro

A senior officer and ace pilot of the Gradosian militia who considered himself a rival of both Eiji & Gale. Once having romantic interests in Julia, she immediately rebuffed him. A sadistic psychopath, Gosterro delights in killing to the extent where his lust for blood overpowers all needs and reason, forcing him to take the lives of his own wingmen. Deeply wishing to kill Eiji, he personally takes the assignment of stopping the rebel with his own SPT-BG-91U Bullgrenn.
