Rear Admiral Yuri Kellerne is the commander of a Zeon military division in Europe and an old acquaintance of the Sahalin siblings. Although he acts gruff and ill-mannered around the Sahalins, he is an honorable soldier who is dedicated to the well-being of the men under his command. After the Odessa base falls to the Federation, Yuri leads his fleeing soldiers east towards Ginias's development base, hoping to use it as an escape route back to space.
