The Holy Grail: What Do You Mean Saber Is Han Xin?

"Saber, Han Xin, answering your summons. Are you my Master?"

What do you mean Han Xin is a Saber?

Am I supposed to take part in the Holy Grail War too?

But with the God of War here, what is there to fear?

What do you mean Lu Bu's in on it too?

I, Liu Xuan, just want to make it out of the Holy Grail War alive.
