The Alliance

The Alliance are a group of Japanese who seek to claim Messiah's base for their own.

Background
Following the destruction of Japan's last safe haven, Arcadia, multiple factions emerged and battled each other to claim resources (food, manpower, technology, etc..). The Alliance was one of those factions and desired to claim the base belonging to Messiah. The Alliance had their spy, Yuka infiltrate Messiah's ranks. At some point, they managed to bribe Yuudai Saejima to their side and made him their mole.
