About

Year 2226, Japan, Neo-Tokyo, N-Ward

The prosperity of Androids. A peace treaty with Aliens. The world was divided into three races.

【Human】 The most populous race in the world.

【Alien】 Descendants of those who invaded Earth in 2045. A diverse race including Greys, Reptilians, and Beasts.

【Android】 Mechanical life forms powered by AI, granted human rights by treaty in 2030.

Civilization ceased its evolution around 2060 following wars and eventual reconciliation between the three races.

However, discrimination and prejudice among the youth of each race continue daily. Humans view Aliens as enemies. Aliens view Androids as enemies. Androids view Humans as enemies.
