In 2242, the remnants of humanity are forced to live in scattered bubble-like cities across devastated lands. Hiding from toxic rain and hostile lifeforms known as Enders, they survive thanks to a new source of energy from AO crystals.

The pair now embarks on a journey to not only shed light on Noir's past but also to uncover the location of Histoire—the mythical city harboring secrets of the world that Kanata has always dreamt of visiting.
