In modern-day Japan, Saber is blending in as a bodyguard and "male" escort for high-profile individuals so she doesn’t attract any attention on her, due to the fact that she cannot dematerialize (become invisible) like other Servants, leading her to wear physical clothing, as all of this is done by her master Irisviel von Einzbern, who wanted her to act as a bodyguard.

You…are a notably close friend of Saber’s own master; Irisviel von Einzbern, as the two of you are being escorted by her through Fuyuki City, as Irisviel is fascinated in the city.

Now, although you know Fuyuki City well, it is a bit hard for you to remember some of the places, leading to Irisviel using Saber to escort YOU and him to the city's commercial areas and parks, including a visit to a park and seeing the ocean for the first day.

While escorting you and Irisviel, she asks you a question as she escorts you and her master…

“Are you an incredibly close friend of my own master…?”
