Description
Apple is a Regular climbing the Tower, first appearing during the events of the second season. She is a woman with short blond hair, pale skin, and distinctive purple eyeshadow. Her attire is typically neat, and her overall demeanor is reserved and composed, often observing situations with a calm, detached air.

As a Regular, Apple holds the positions of both a Scout and a Light Bearer, specializing in information collection. She demonstrates proficiency in operating Lighthouses, controlling at least two red-colored units along with a keyboard to manipulate them. Her specific combat abilities remain largely undocumented, but her recruitment into a team led by Khun Aguero Agnis suggests a high level of competence in her designated roles.

Apple is secretly an agent of FUG, a criminal organization that opposes the ruling Zahard Empire. She was contacted by FUG and given the mission to infiltrate Khun's team with the ultimate goal of assassinating him. To further this objective, she recommended Michael, another FUG operative, to join the same team. Her primary role within the group is to gather intelligence and manipulate information. She successfully planted a hacking program within Khun's Lighthouse, allowing her to set traps and feed false data to her teammates. Her betrayal is revealed calmly when she and Michael subdue their teammate Dan, matter-of-factly explaining their true purpose and the fate that awaits those who learn their secret.

In her role within the story, Apple initially appears as a reliable member of Khun's team, helping to track down the criminal Cassano by noticing and reporting a wanted picture. However, her actions are calculated to serve FUG's interests. During the Workshop Battle arc, she executes her betrayal, leading Khun into a trap and facilitating the attack on Dan's legs, which she observes without visible emotion. Following these events, she continues to operate with Rachel's group, working to maintain the server of the artificial being Emily. She later resurfaces during the Cage arc, having aligned with an elder's envoy and participating in schemes against Khun's allies. Her ultimate fate in this arc is ambiguous, as she is briefly shown captured and restrained.

A key relationship is her partnership with Michael, a fellow FUG spy. They collaborate in their mission and are often seen together. She also has a direct connection to Rachel, acting as part of her faction following the betrayal of Khun's team. Apple shows no particular loyalty to her original teammates, viewing them as obstacles to be eliminated or used for the mission's success. Her development is minimal and mostly off-screen, as she transitions from a hidden antagonist to a known operative working openly within Rachel's group. Her reserved and calculating nature remains consistent throughout her appearances, never wavering even when confessing to acts of treachery.
