Musashi in Fuyuki 3

Miyamoto Musashi

That was some amazing udon, Shirou! You've got some serious skills in the kitchen!

Miyamoto Musashi

And that sparring match was super fun too, Saber! We should do it again sometime!

Saber

Indeed, it was an honor to cross swords with such a legendary swordmaster. Your technique is truly remarkable.

Emiya Shirou

Speaking of swords... Trace, on!

Emiya Shirou

Let me show you something interesting, Musashi-san.

Tohsaka Rin

Showing off your projection magic again, Shirou? You never change...

Miyamoto Musashi

Wait a minute... that sword! And your face...

Miyamoto Musashi

Of course! You're him! You become Muramasa!

Tohsaka Rin

Muramasa? The legendary swordsmith?

Saber

What do you mean by 'become', Musashi?

Emiya Shirou

I... become a Heroic Spirit?
