Description
The Black Hair Daemon is a minor but memorable character in the anime My Daemon, known for its brief yet haunting appearance. As its name suggests, this daemon is distinguished by its most prominent feature: an abundance of long, black hair that covers much of its body. It also wears a cracked white mask, which adds to its eerie and unsettling visage.

This daemon is encountered as a captive within the laboratories of the Peace Organization, a powerful group that conducts often cruel research on daemons. The character exists solely as a test subject, and its background is one of suffering and exploitation. A researcher named Baruta Tazawa, who is responsible for its mistreatment, callously explains that he removed part of its scalp to study the bodily fluids that make its hair so luxurious, with the goal of developing commercial hair products. This treatment exemplifies the harsh and inhumane reality for many daemons in the series, who are viewed as tools or vermin by humans.

In the story, the Black Hair Daemon serves to highlight the innocence of daemons and the brutality they endure. Its role is not to drive the main plot but to act as a powerful emotional catalyst for the protagonist, Kento Tachibana. When Kento and his companion Kaede infiltrate the Peace Organization to rescue his own daemon, Anna, they pass by the capsule holding the Black Hair Daemon. Kento possesses a unique empathy for daemons, and upon seeing this imprisoned creature, he experiences a psychic flash of the torture it has suffered, visualizing a circular saw descending upon it. In this moment, he hears its unspoken plea for freedom, further strengthening his resolve to oppose the organization's cruelty. The character does not undergo personal development, as its screen time is limited to this single encounter.

Regarding its abilities, the Black Hair Daemon does not demonstrate any overt powers in its brief appearance. Its primary notable characteristic is its appearance, specifically its remarkable hair, which is the focus of the researchers' unethical studies. While it does not fight or use special skills, the implication is that its hair possesses unique properties that make it a subject of scientific interest. The character's ability to communicate its suffering to Kento, likely through a form of empathic or psychic link that some daemons share with him, is the closest it comes to displaying a notable trait. Despite its short role, the Black Hair Daemon left a strong impression on viewers, ranking among the top twenty most popular characters in an official fan poll conducted by the production studio IGLOO STUDIO.
