Shion Uzuki

Shion Uzuki (シオン・ウヅキ) is the main protagonist and heroine of the Xenosaga series (with the exception of Xenosaga: Pied Piper, which focuses on Ziggy). Shion is the daughter of Suou Uzuki and Aoi Uzuki, and younger sister of Jin Uzuki, her older brother.

Shion seeks to save the universe from the Gnosis, as well as from an ancient religious cult known as Ormus.

In the beginning of the series, Shion is a Camelle Vector Industries First R&D Division computer scientist and programmer. She helped build KOS-MOS to combat the Gnosis because her deceased boyfriend Kevin Winnicot, original creator of KOS-MOS, was unexpectedly killed by the KOS-MOS Archetype.

In Xenosaga Episode I, Shion is Head and Chief Engineer of the KOS-MOS Project. Shion eventually quits Vector and joins the anti-U.M.N. underground resistance Scientia by Episode III.
