Clay is a male student attending Rosewood Academy, a training ground for those who aspire to become heroes. He is depicted as a teenager with brown eyes and brown hair that falls to his neck. Within the academy, Clay is recognized as a swordsman who works toward the goal of being promoted to a higher class.

In his interactions with fellow students, Clay shows a competitive spirit, particularly when paired with his friend Cassim. He participates in tag-team matches against classmates Claire and Yessica, displaying pride in his abilities and a strong desire not to lose, especially to the female students. This pride is tied to his personal feelings, as Clay admits to having romantic interest in Yessica, which influences his reluctance to be defeated by her. When he and Cassim experience a loss, Clay reacts with visible humiliation and shame, choosing to isolate himself from the group rather than join them for lunch. Despite his competitive nature, Clay shows capacity for emotional vulnerability and growth, accepting a pep talk from a peer who reassures him that losing is an acceptable part of improvement.

Beyond his rivalry and budding romance with Yessica, Clay becomes involved in other social dynamics at the academy. On one occasion, he finds himself in a close personal situation with another female student, Iona, indicating his character continues to be developed through various romantic and comedic scenarios within the school setting.

As a supporting member of the student body, Clay participates in the academy's training exercises and tests, including the use of a virtual reality system designed to challenge the students' abilities. His role is largely defined by his relationships with his peers, including his partnership with Cassim and his interactions with the female students, through which his personality and motivations are further explored.
