An official Japanese manga adaptation for the first game in the Xenosaga series. It was written and illustrated by Atsushi Baba and serialized in Monthly Comic Zero Sum. While making very major omissions and rearrangements, Xenosaga Episode I: Der Wille zur Macht starts out as mostly faithful to the PlayStation 2 original. By the end of the manga, major omissions are made to the story, even by excluding entire characters and set pieces.
