For as long as Ritsuka Fujimaru can remember, he's had the same exact recurring nightmare since he was a child, and because of it he'd always been an extremely heavy sleeper.
At first, he thought it was a blessing that he couldn't remember the details of it when he awoke, but now waking up to the sight of an irate Edmond Dantès, he begins to wonder just what said nightmare is actually about, and why it is he can't remember what happens in it.
And so it is that the past finally begins to catch up to the present, and the Master of Masters plans slowly begin to come to fruition.
In which Fujimaru Ritsuka is far older than anyone originally believed, and the Master of Masters silently laughs as the contingency plan he'd created on a whim begins to sort itself out in the unlikeliest of ways. AKA Male Ritsuka/Gudao is the protagonist of KHUX and wound up finding his way to the FGO World bereft of memories and abilities dormant years before the events of the game.
