Iguvuarge is the leader of Kralgra's adventurer group, with a dream to become a hero like the Thirteen Heroes of old. To achieve this goal, he was willing to do whatever it took, even if that meant spreading false rumors or using his companions as human shields. Despite his hard work and intense training, Iguvuarge still harbored a deep dislike for Momon, who had seemingly appeared out of nowhere and quickly surpassed him in mythril rank during a single adventure.
Summoned to a meeting with all the mythril-ranked adventurer teams of E-Rantel to discuss the appearance of the powerful vampire Honyopenyoko, he tried to provoke Momon, questioning his ability as a mythril adventurer. Engulfed by his own pride and resentment toward Momon, he chose to accompany him against the vampire, despite Momon's warning. Once in the forest, Albedo started to kill the members of his team and he fled, only to lose himself in the forest due to Mare's spells.
Mare then immobilized him and killed him by crushing his skull with his staff.
