Counter Guardian Emiya is a man of many regrets. Among them, the fact that he wasn't able to save his Saber when he was a boy continues to haunt him to the end of days. Now, however, a chance has mysteriously appeared to change that result. And being the practical man he is, he will not hesitate to seize it. But still... why in Alaya's name is Artoria his new Master in this world?

Alaya is gone. The Counter Force is gone. Without them, the Throne of Heroes released all the Heroes on Earth against the planet's will. When Gaia sensed that the World is on the brink of collapse, she sent its First Hero to fix the mess. Now, Shirou Emiya has to save the day once again. What can a Retired God, a Treacherous Knight and a Boastful King do to save the planet? [AU]

One day, the news spread like wildfire. "The Black Dragon is dead," they said. "The strongest Monster has been killed," they cheered. Yet, no one knew how it happened, nor who did the deed. At the same time, weird phenomena began happening in the Dungeon, plunging Orario into alarm. But that has nothing to do with the boy who's recently started to work at a certain Tavern... right?
