Saber of Red took a stance with the silver sword. At the same time, the heavy face-covering helmet split into two and became one with the armor.

Their eyes met. Saber of Black raised his eyebrows a little, as though in slight surprise. But of course, for the Saber of Red had the face of a young girl. Normally, Servants were summoned in the form of their peak. As such, most heroes were in their twenties and thirties, their prime.

However, she was clearly too young. It was likely that she hadn't even reached twenty.

Besides, the fair features of the girl did not conceal her brutal nature—rather, she did not bother to conceal it in the first place. In her eyes, glaring fixedly at Saber of Black, there was a mix of the joy found in battle, and cruelty.

"...Why did you remove your helm?"

Red answered the question of Black, sounding irritated.

"It's nothing. I just can't activate my Noble Phantasm without taking it off first. Do you not have more pressing matters at hand, Black?"
