The orphans are the children under the care of Kamado Ueshita. They are very loyal and supportive of her. The orphans themselves are a force to be feared, because they all possess Apprentice Diaries, although the only ones shown being used were the Orphan Diary and the Copy Diary. The Orphan Diary was very useful, allowing them to coordinate their attacks, but the Copy Diary was of little use. They lost their diaries when the jammer on John Bacchus' car cut off their siginals to Eight, but even without their diaries they are still skilled in battle, namely close combat, use of firearms, explosives, infiltration, etc. Also being orphans under her care, the Seventh duo, Marco Ikusaba and Ai Mikami are under her command, or at the very least are allies. Though, there was little interaction shown.
