Gido Gaira

An ambitious high ranking officer in the Theseus army who happens to resemble Sam's brother a lot. It is suggested that he is an "Ideal Children" in a body of a Natura, in particular, Dick Coyne's body. Regained his memory a little as Dick after Gido fell off his ship. He said the heart of the stranger he got in his body might get awaken soon, so he sacrificed himself by launching the weapon he made before went missing the "Monokeros" at Ozma so everyone can survive.
