Ngurlni acts as a fiercely loyal subordinate to the trickster deity Loki within Ikusa Otome Suvia, carrying out his master's unsavory tasks with unwavering allegiance to Loki's objectives. He commands hordes of monstrous troops—beastmen, goblins, and tentacle monsters—who operate under his direct command. These forces mirror Ngurlni's own brutal methods, exhibiting savage brutality and a total absence of scruples, reflecting his ruthless leadership style aligned with Loki's schemes.
A past confrontation with the Valkyrie Sigurd left Ngurlni permanently disfigured; she blinded his right eye in an injury that defies his regeneration, leaving an unhealed wound. This irreversible damage fuels an intense, singular desire for vengeance against Sigurd, becoming a defining obsession that drives him. His hatred burns exclusively for her due to this permanent injury.
