For this new world, abandoned by God ... the human species coexists with the shadows, where the Ghouls, creatures of the night, demons eager for human flesh, are sheltered among their ranks a sword ready to cut from the roots the evil.

It's been ten years from the last Heaven Feel and Shirou Emiya is still falling back into the path he had promised to stay away from. A curious package and a letter from Tokyo could actually make a difference. But can Shirou truly save himself from Fate?

Kariya was right to distrust Zouken. His rejection of the offered catalyst led not to the summoning of Lancelot, but a different Servant perfectly suited for him who had experienced his own fair share of tragedies. A Servant who would guide Kariya and protect Fuyuki. No matter the identity, he would never lose sight of his goal. Beware all, the King of Ghouls is ready for war.
