Maria is a powerful demonic entity that appears when the area manager Maris fuses with the Satan Maria sticker in the anime Bikkuri-Men. She is a demon head originally created to defeat Saint Phoenix, and during the previous Holy Demon War she served as a subordinate of Super Devil. Her background is rooted in the ancient conflict between angels and demons, making her a formidable antagonist aligned with the Devil Store faction. Maria's personality is driven by her purpose as a weapon against angelic forces; she exhibits a cold and ruthless demeanor in battle, methodically carrying out her mission to destroy her enemies. Her motivations are shaped by her loyalty to Super Devil and her intrinsic role as a destroyer of holy beings. Within the story, she functions as a major obstacle for the protagonists, particularly in the ongoing struggle over valuable Bikkuri-Man stickers. Maria's key relationships include her connection to Maris, whose fusion with the sticker enables her manifestation, and her rivalry with Saint Phoenix, her intended target. She also answers to Super Devil, and her actions directly support the ambitions of the Devil Store. Her notable abilities include super psychokinesis, which allows her to control other demons, and the power to melt the holy hearts of angels using demonic flames. These powers make her a dangerous combatant capable of overwhelming ordinary opponents. Little development is shown beyond her role as a loyal and destructive servant of the demon side, though her presence escalates the conflict significantly.
