Fate: Parallel War

Nine years ago, an unfamiliar man entrusted Zhaoye to Kiritsugu Emiya, making him the second child of the Emiya family.

Nine years later, the Holy Grail War begins anew in Fuyuki City. Heroic Spirits appear in the streets, and mages kill each other in secret, but none of it seems to have anything to do with Zhaoye.

All he knows is that there's a quiet silver-haired girl at home now, sitting by the window with a teacup all day as she watches him roughhouse with Shirou, get teased by Taiga, and receive Sakura's care. He also knows she doesn't turn down a cup of tea handed to her, a bottle of painkillers bought for her, or a set of casual clothes prepared for her.

The Holy Grail bleeds, and the world burns.

But life at home goes on.
