Alexander is Salome's masochistically devoted servant. He displays unwavering loyalty and clear infatuation towards the gothic-lolita antagonist, willingly enduring unpleasantness for her benefit. Salome accepts his service without reciprocating his feelings, though she is not portrayed as particularly abusive. Following Salome's defeat and firing by Black Trader, Alexander follows her into exile at the South Pole. His role centers on assisting Salome in her battles against the Twin Angels, operating the giant robots she constructs for combat. Their dynamic persists unchanged throughout their appearances, with Alexander providing steadfast support regardless of challenges. Details prior to his service to Salome remain undocumented, and he has no involvement in other story arcs, media, or spin-offs beyond this focused role alongside her.
