Despite being a hybrid of Hey and Primordial animals, Kinileutan gained high popularity even among Heys with his kind nature and manly appearance. Kinileutan maintained the balance of Hellmarsh by killing the dark beings summoned by Thrymgjor, thus enhancing his reputation. Thrymgjor had no choice but to complain to his master, Hakan, about Kinileutan's actions, leading Hakan to forcibly brainwash Kinileutan's body and mind, making him a slave to Weidete's special forces, the Skurami Division.
