Tough, calculating, and driven, Rochina is a Melkian intelligence officer who investigates the raid of Lido and finds a lone Chirico Cuvie drifting in space. Although his interrogation of Chirico produces no information, Rochina is convinced of a connection between Chirico and whoever kidnapped the top secret Perfect Soldier. Under the orders of his superior officers, General Battentian, Rochina and his spy network keep a close watch on Chirico in Uoodo City and Kummen, unsure of the level of his involvement with the mysterious Secret Society.

As he becomes more deeply involved with Chirico's progress, Rochina defects from his own military in order to continue the pursuit. This involves a complex game of capture and manipulation, in which Rochina himself is merely the pawn of a greater power.
