In Unicorn Overlord, you’ll encounter various fierce characters as you explore. You can choose whether or not to include them in your army. Similarly, you’ll encounter Nina, a member of the Rock Rat bandits. If you want to recruit Nina in Unicorn Overlord, you’ll need to complete a certain side quest. To learn more about this unit and how to add her to your team, here’s everything you need to know.

To recruit Nina, you first need to talk to Mille. You will encounter this character before starting the sidequest "Uprooting the Rock Rats" in La Criselle Town. Once you talk to her, Mille will ask you if she can join your army (temporarily), as she is looking for someone.

Once you start this side quest, Mille will tell you that the person she is looking for is her sister Nina, and if they run into her, she will want to have a word with her. You will then need to use Mille's help to break down the field of barricades at Tiche Donne Town.

After this, Mille and Nina will reunite; but this reunion will not be pleasant. As soon as they exchange a few dialogues, the fight will begin and Mille will talk to Nina once she defeats her.
