Originally named as AL-1S, Alice is a mysterious member of Millennium's Game Development Dept. Found in an abandoned munitions factory at the Ruins, it's impossible to retrieve any information about her origin nor her age.
She enjoys playing games with Yuzu, Momoi and Midori and becomes a serious game fanatic, resulting in most of her conversation unnaturally taken from familiar lines from retro games.
