M is a character from the anime Infinite Stratos 2 who serves as the leader of the underground organization Phantom Task. She is a highly skilled Infinite Stratos pilot and first appears near the end of the second season, revealing her connection to the main protagonist. Her background remains largely mysterious, but she is depicted as cold and ruthless, showing a willingness to harm or kill others without hesitation. She holds a deep sense of superiority due to her own abilities and frequently looks down on those around her. Despite her leadership role, she is not naturally obedient to the organization; to ensure compliance, nanomachines have been implanted in her body as a monitoring and control measure. Her motivations are initially unclear, but her actions drive a significant conflict in the story, placing her in direct opposition to the main characters. She has a notable connection to Ichika Orimura, the male lead, and her true identity is hinted at throughout the series. Her abilities as an IS pilot are formidable, likely exceeding those of many other characters, though specific details of her fighting style are not extensively shown. Over the course of the narrative, she remains an antagonist whose presence escalates the stakes for the protagonists.
