Magiquone is the series' main antagonist, driven by an obsessive need to conquer all of Gamindustri and defeat the four goddesses. She and Histoire were once close, but that changed when Magiquone orchestrated the division of Gamindustri into four regions—and promptly turned on her former ally to seize total control.
Personality-wise, she's volatile and easy to provoke. Her intolerance for failure is matched only by her hatred of losing, and she's notorious for being loud, hot-tempered, and quick to blow up over setbacks. Histoire has pointed out how much Magiquone's temperament mirrors Blanc's. She can't resist boasting and gloating, always staging some kind of dramatic entrance complete with a theatrical laugh. Whether it's genuine confidence or overcompensation, she needs to make an impact whenever she shows up.
