神討ノ機神 -deus ex machina-

In 2010 humanity is wiped out by the Araburugami, hostile deities manifesting as giant monsters. Only one survivor remains in Tokyo, a city converted into an automated military fortress — warrant officer Aoki Itona, pilot of the 100 meter tall anti-deity robot Shinuchi Mark V, a Deus Ex Machina.

Itona enjoys the loneliness, but one day she meets a fellow pilot and the last survivor from another region, Kurenai Touka. Itona's introverted personality keeps clashing with the upbeat and teasing Touka as they grow closer and join hands to fight against the wheels of fate.
