Miyuki Itsumi

Miyuki Itsumi is a guest character in the Xenosaga series.

Episode I
Miyuki works as a systems programmer at Vector's First R&D Division. She is a colleague of Shion's and is considered a mechanical otaku. She works on various inventions, emailing information about them to Shion throughout the game. Shion is often plagued by expense authorization requests from her as a result. Miyuki's first appearance in the game occurs after Shion and the others make their way to the Elsa. Miyuki, via a video communication, passes along orders to Shion to pass along KOS-MOS to the Second R & D Division on Second Miltia. Shion gets very upset at this, forcing Shion's director to intervene. After the director agrees to Shion's demands, Miyuki comes back on screen and praises Shion, telling her how happy she is that she is safe. Miyuki didn't notice that Allen was in danger or was even there with Shion until he speaks up about it. Miyuki appears again later in the game after the Dämmerung appears near the Kukai Foundation and fires the Rhinde Maiden. Miyuki expresses pleasure at being transferred to Second Division, enabling her to see it up close. Miyuki sends over information about something in the area attracting the gnosis but being hidden by a force field. Miyuki proposes linking up the Dämmerung's mainframe with KOS-MOS' D.S.S.S. sensor and provides a PT cartridge to Shion which Shion claims is too dangerous to use. KOS-MOS is able to use the cartridge safely however, revealing the Song of Nephilim.

Episode II
Miyuki appears at Vector Industries First R & D Division on the Dämmerung while Shion is stationed there. Shion has a hard time keeping her attention while talking to Miyuki and stops their conversation. Shion is able to visit Miyuki in a nearby room. Miyuki also appears at the end of the game when Shion and Allen have returned to the Dämmerung, telling Allen he has a lot of reports to fill out.
