Spoiler:

The soldiers are searching for her, so she took refuge in Celia's father residence who's on her side. Knowing the knight Haruto, she asks him for his help to escape from the soldiers after her and he accepts. While escaping, they encounter Reis (who also reveals Rio's identity, so Christina now knows Haruto = Rio), but because they don't have time and Rio isn't alone, he lets Reis escape instead of fighting.

The other girls aren't far, they're in the forest nearby the kingdom, iirc.
