Aniplix USA has just released Fate/Grand Order on mobile devices for both Android. Here's the synopsis from the app store:
2017 A.D.
Chaldea, an organization tasked with observing Earth's future, has confirmed that human history will be eliminated at 2019.
Without warning, the promised future of 2017 disappeared.
Why? How? Who? By what means?
AD. 2004. A certain provincial town in Japan.
For the first time ever, a region that could not be observed appeared.
Assuming that this was the cause of humanity's extinction, Chaldea carried out its sixth experiment - time travel into the past.
A forbidden ceremony where they would convert humans into Spiritrons and send them back in time. By intervening in events, they would locate, identify, and destroy the space-time Singularities.
The mission classification is an order to protect Humanity: Grand Order.
This is the title for those who would take a stand against human history and battle fate in order to protect mankind.
Do you think it sounds promising?
