Ukumori is a white haired Kildren, codenamed Sprite, that believes in strength alone. He commonly looks down on the fallen, suggesting they were weak, much to the anger of others. Ukumori sees himself as the best of everyone, and commonly makes challenges to others, verbally insulting their skills as well. At the end, Ukumori defects with Tochika Mozume in the idea with Rostock's successes, victory had to be given to Lautern to balance the war. As he battles Cheetah, He shows a severe jealous streak of Cheetah, claiming all his fame and recognition should be his instead. However, he is killed when Cheetah shoots him down. It was unknown if Ukumori was recloned afterwards.
- Coincidentally, Ukumori's voice actor, Yuri Lowenthal, also voices Larry "Pixy" Foulke in another game produced by Project Aces, Ace Combat Zero.
- He is similar to Wolf O'Donnell from Star Fox and Sulejmani from Ace Combat: Joint Assault, as both characters also have a personal vendetta against the protagonist and wish to fight them one-on-one to prove themselves the best.
- During Mission 6 he is well-known for his obnoxious commentary on the situation, but when you pan your camera around to view the other pilots he and his plane are nowhere to be seen. Just where was he that time?!
