Tron is a female character standing 143cm tall with yellow or blonde hair and purple eyes. Her demonic heritage, being half-demon and half-human, meant she never felt she belonged in the human world, the demon world, or among the Satanists she was once associated with. Her anime design features extremely long hair reaching the ground, often tied in a ponytail or side tail, and she wears Gothic Lolita-style clothing accessorized with hair ribbons and a choker.

During a conflict between Oruit and Killer Queen, Tron used her "Abyss" ability to create advantageous conditions for the demon side. In this battle, Oruit attempted to gain strength by sucking her blood, leaving her near death. Kirisame Zero intervened to save her life by administering a recovery item called "Calorie Maid."

Tron possesses the innate gift of "Soul Perception," which allows her to perceive the colors of people's souls to distinguish good from evil. This ability enables her to recognize that Hakuto Kunai and Kirisame Zero are the same person. After this realization, she actively pushes to join Kunai's group, becoming one of his subordinates.

Her experiences with Kirisame Zero, especially his life-saving actions and his treatment of her, lead her to develop romantic feelings for him, mirroring Killer Queen's attraction to the same character. She persists in following Kunai despite his initial resistance, eventually integrating into his group and sharing living quarters, including sleeping arrangements alongside other female characters like Aku and Luna.
