Description
Mary is one of the three main characters in the original video animation.hack//Quantum. Her real name is Eri Etou, a female high school student living in Aomori Prefecture. She was introduced to the massively multiplayer online role-playing game The World R:X by her childhood friend Asumi, the player behind the character Sakuya. Within the game, her player character Mary is based on the appearance of a previous character named BlackRose, distinguished by long pink hair tied in a ponytail and a rose accessory worn on the left side of her head. She plays as an Edge Punisher class character, a fighting style that contrasts with her personality.

Mary possesses a caring and sincere nature. She is the most balanced and practical member of her friend group, often suggesting logical approaches to problems that arise during their adventures. Her seemingly boundless kindness is frequently tested by the impulsiveness of Sakuya and the cold demeanor of Tobias, and she often finds herself cleaning up the messes left by her companions. In reality, she is much more serious and grounded than her in-game counterpart might suggest. She is not a natural leader, yet her intelligence and reliability make her an essential part of the team. She has a protective side, as demonstrated when she helped a younger player who was being bullied by others.

Mary's primary motivation is supporting her friends and maintaining harmony within the group. She plays The World for the camaraderie and the shared experience of adventure, rather than for personal glory or power. In the story, she, along with Sakuya and Tobias, takes on an unbeatable quest called The One Sin, which draws them into strange circumstances that blur the line between the game and reality. Her role in the narrative is that of a steadying influence and a voice of reason, balancing the group's dynamic and helping to solve both in-game puzzles and interpersonal conflicts.

Her key relationships are with her two party members. Sakuya is the enthusiastic and impulsive leader of the group, which often forces Mary to act as a mediator. Tobias is a more reserved and calculating player, whose coldness can clash with Mary's warmth, but the three ultimately form an inseparable team. The bond between them, both inside and outside the game, is central to the story's exploration of friendship and teamwork.

Mary's abilities within The World R:X focus on support and long-range magical attacks. She has a calm and collected fighting style that complements her personality, and she is highly proficient due to her experience and dedication to understanding the game's mechanics. Over the course of the series, Mary develops through the challenges the group faces, learning to trust her friends more deeply while also asserting her own perspective when necessary. Her growth emphasizes the value of cooperation and the strength that comes from a balanced, supportive team.
