イシス

G2 ICS, more commonly referred to as Isis, is the second high-performance Guardian constructed by the Dark Lord Satella and an antagonist in Rance 03. Isis was created at some point during Satella's adolescence. Satella put considerably less effort into his design compared to that of her previous guardian Caesar, which resulted in him having a substantially smaller body and no mouth whatsoever. While this somewhat haphazard design approach caused Isis to be significantly weaker than Caesar and completely incapable of verbal communication, his more lightweight and aerodynamic body nonetheless made him very agile and effective as a fighter.
