Description
Ai is a notable character from the anime series, recognized by her alias "Odd Eye," a name she earned as a skilled thief specializing in stealing Lost Precious items. She is a young adolescent girl with brown hair and distinctive eyes, one of which is a unique golden color, giving her the nickname that defines her reputation.

Her background is rooted in tragedy and manipulation. Ai was kidnapped from her family fifteen years prior to the main events of the story by a man named Furumori, a high-level researcher and Breaker. Furumori used her as a test subject for a forbidden experiment, forcibly integrating a Lost Precious into her body. This process granted her werewolf-like attributes but also reshaped her identity, as Furumori lied to her, claiming her family was dead and that she was born a half-wolf. Under his control, she was trained to become a thief, serving as a tool for his schemes and research. Her real name is Aika Makihara, and she comes from a wealthy family; her father was the president of a large company who withdrew from Lost Precious-related society activities following her disappearance.

In terms of personality, Ai initially appears as an adversary, dutifully following her master's orders without question. However, her demeanor is largely a product of her conditioning. Deep down, she is a victim seeking approval and a sense of belonging. When she discovers the truth about her past, she exhibits a strong will to break free from her manipulation. Despite the betrayal and abuse she suffers, she shows a capacity for forgiveness, as she still cares for Furumori even after turning against him. Her experiences lead her to value genuine kindness, which she finds in others, and she ultimately chooses to keep the powers she was given, embracing them as part of who she is rather than a mark of her captivity.

Her primary motivation throughout her story arc is the search for truth and freedom. For years, she operated under the false reality created by Furumori, believing she was a monster with no family. Her motivation shifts dramatically when she acquires a pair of earring-type Lost Precious that allow her to read minds. Using this artifact, she hears Furumori's true thoughts, confirming that he kidnapped her and sees her only as an experimental subject. This revelation drives her to rescue Ryuji, who has also been captured, and to escape her life of servitude. After resolving her conflict with Furumori, her goal becomes returning to her biological family, which she successfully accomplishes, though she maintains her connection with the friends who helped her.

In the story, Ai serves as a central figure in a dedicated story arc. She is introduced as an antagonist who steals Lost Precious and captures the protagonist, Ryuji. However, her role evolves into that of a temporary ally. Her personal struggle against Furumori highlights the darker aspects of the Lost Precious criminal world, showing how these artifacts can be used to exploit and harm individuals. After her arc concludes and she reunites with her parents, she continues to play a supportive role, later assisting Ryuji and his companions in their battle against the primary antagonist, Onyx.

Key relationships define her journey. Her relationship with Furumori is the most significant and toxic. He acts as a deceptive father figure, raising her as his ward while secretly viewing her as a tool for his experiments. Her betrayal of him is a pivotal moment of liberation. In contrast, her relationship with Ryuji is one of salvation. He accepts her wolf form and treats her with kindness, which inspires her loyalty and affection; she continues to visit him even after returning to her family. Her relationships with Rose and Eriko transition from adversarial to friendly as they unite against a common enemy. Finally, her reunion with her biological parents represents the restoration of her lost identity and a happy resolution to her long kidnapping ordeal.

Ai undergoes a significant development from a manipulated pawn to an independent individual. Starting as a loyal follower, she shatters her conditioning upon discovering the truth and actively rebels against her oppressor. The climax of her development occurs when she decides to return to her original family, reclaiming her human identity as Aika Makihara, while simultaneously choosing to retain the wolf abilities that had been forced upon her. This decision signifies her acceptance of both her human past and her transformed present.

Regarding notable abilities, her powers stem entirely from the Lost Precious implanted within her body, represented by a tattoo. This artifact allows her to transform into a half-wolf, granting her superhuman physical attributes including enhanced strength, durability, agility, stamina, and speed. These abilities, combined with extensive training in stealth and combat, make her an exceptional thief. Her heightened senses and physical traits, such as sensitive wolf ears and a tail, are direct manifestations of the werewolf Lost Precious integrated into her being.
