Through tragedy, Issei awakened a power which places him as a Predator, one of the most dominant beings on the planet. As the Eighth, he must defend the planet from a force beyond his current means. Ideals clash, blood is shed, and hearts are broken in his struggle to protect those he loves most dear. But he can do it. He has become Y Ddraig Goch. (Slight AU, OP Issei, OCs inside)

Honestly, Shirou was beginning to think that he should be used to this; being unwittingly selected to take part in brutal tournament that he had no idea existed until he found himself in the middle of it. Then again, second times the charm, right?
