Shion Uzuki is the main character of the three episodes of Xenosaga, which have been referred to as "Shion's Arc" by Namco Bandai. While her role is less prominent in Xenosaga Episode II, which focuses on the character Jr., she is the lead character again in the DS remake Xenosaga I & II. While Shion's surname is "Uzuki", Takahashi has stated that she is not meant to be a distant relative of the character Citan Uzuki from Xenogears. She does, however, share his liking for science.
