known simply as Perfect Works, is a book covering the storyline of Xenogears. In addition, Perfect Works describes an enormous backstory of Xenogears, including world building and canonical character details that never made it to the game's script.
Perfect Works also contains a timeline which corresponds similarly to the Xenosaga series. However, like other games in the Xeno- series, it is a separate universe from Xenosaga.
