Ilmari was notoriously lazy, but there was one person who could stir him to action: Riela. Ilmari was even willing to resume practicing his trumpet because it seemed to please her. One day, Nameless needed someone to act as bait in order to lure out some imperials. Riela volunteered for the task, but Ilmari insisted on taking her place. By playing his trumpet, Ilmari successfully caught the imperials' attention and the mission was a success. Ilmari was always willing to do anything to make Riela happy, even though he knew her heart belong to Kurt.
