Personality

Background
Sienna has been a devoted follower of Katarina Claes for quite some time. When Sienna was feeling down about her own magical prowess, Katarina informed her that her own magic was basically non-existent. She told her that she should be proud of her noble status, and since than has stuck by Katarina's side even after she regained her memories.

Game Description
In the original Fortune Lover game, Sienna can be assumed as being one of Katarina's many followers who bully the protagonist throughout the story.

Katarina Claes
Sienna is Katarina's longest follower, and admires the Duke's daughter a lot. Before Katarina's memories of her past life returned, she has taught Sienna to hold her chin up as her follower, and learn to be more proud of herself. Being around a Duke's daughter gave Sienna more confidence while in the academy, and led her to become friends with other noblewomen in Katarina's follower circle.

After Katarina gains memories of her past life, Sienna has been the subject of Katarina's attention due to her desire of not being left alone. Sienna gets slightly agitated by Katarina's childish behavior, but never mentions of it being out of character. Katarina still voices her amazement at Sienna's hard work, which makes her realize that despite suddenly changing in personality, she is still the noblewoman that she admired and followed. While Katarina and herself were close before, the two now actively study and have tea together outside of Katarina's follower circle.

Maria Campbell
Sienna dislikes Maria, due to all the attention and influence she is receiving thanks to her Light Magic. As someone who is also studious and hardworking, Sienna's opinions of Maria started to change at the realization that her achievements are fruit of her labor. Eventually, Sienna realizes that her judgment of Maria was incorrect, and desired to work alongside Katarina in gaining her forgiveness.

As Katarina and Maria become friends, Sienna is naturally around her as they all hang out. Even though Sienna can have a conversation with her when Katarina is around, she doesn't know how to talk to her when they are alone. After Sienna apologizes to Maria for the harassment that she helped escalate, the two have grown close and promised to study in the library together.
