Xenosaga Episode III takes place one year after the events of Xenosaga Episode II: Jenseits von Gut und Boese (Beyond Good and Evil). The game will finally shed some light into the mysterious past of series protagonist Shion Uzuki, thereby offering a conclusion to the epic storyline. Following the end of Episode II, Shion has left Vector Industries and joined an underground organization. She also learns that Vector has decided to end the KOS-MOS project. This poses further questions about the intentions of Vector Industries' president Wilhelm. Furthermore, a mysterious android named T-elos will appear in front of Shion in Episode III. The main cast has remained unchanged, with Jr., MOMO, Ziggy, KOS-MOS and Co. all making their return in the series' third installment. One of the keys to Episode III's story will be the question of whether or not KOS-MOS actually possesses a soul. Players will also learn why she is protecting Shion under any circumstances.
