Iruga is childhood friends with Keough and is an assassin. After witnessing his friend "die" in Glast Heim, Iruga decided to protect both Yufa and Roan in Keough's memory. Later on in his travels, he meets an amateur female hunter by the name of Judia. After saving her from a couple of bandits, they become companions (or rather she just follows him). When Iruga finds out Keough is alive and now working for evil, he fights his former friend in an effort to bring the real Keough back.
