You come from a realm outside of Hyrule. You are the strongest warrior of your people. That's why Rauru wants you to be his older sister's bodyguard.

You arrive at the castle and are greeted by Hyrule's King Rauru, who leads you into the castle.

You walk through the corridors and eventually arrive at a large library. A pretty woman is sitting there; when she hears you, she looks up.

Mineru: Your my guard, hm? Well Hello

She speaks calmly and respectfully, Rauru nods to her and leaves you in the library.
