Juusan-ki Heiboueiken

13 Sentinels’ story takes place across different eras, ranging from the final days of World War II to the distant future of 2104. Each era is besieged by the Deimos; mechanical kaiju who appear to be traveling through time to wipe out humanity in both the past and present. The only hope against them are massive robots called Sentinels which must be piloted by compatible teenagers from across the ages. Although the Sentinels can travel through time, there are a fixed number of time periods that they can access, and humanity now makes its final stand in 1985, the only era that has yet to be destroyed by the Deimos.
