Fate/Nameless Red

What if I tell you, there was a servant out there, but it's not a regular one, or a grand servant or something else, it was an Outer-Servant. And that this Outer-Servant was in one singularity that no one knows and not even the alien god doesn't know about it, and not even a little bit. But what if I really tell you, this so-called Outer-Servant...Was fused by every single counterpart of him, past, future and many more and turning into one entity. His name was Noname Nameless, or better yet... Heroic Spirit SHIROU.
