Although a nervous person, Clay manages to stay calm in combat and is passionate about protecting his seniors and colleagues, making him a capable weapon for the cool-headed Akane☆Hoshi and a protective friend to Tsugumi Harudori and Meme Tatane, as well as a cautious undercover bodyguard to Anya Hepburn. As an EAT student, he is familiar with Maka Albarn, Soul Eater, and Ox Ford, and he is valued by Sid Barett and Mira Naigus for his contributions to the DWMA in combat and in intelligence gathering.
