Christina Beltrum is the first princess of the Beltrum Kingdom. She is also the older sister of Flora Beltrum. Rio first meet with princess Christina in the slums as she was searching for her abducted sister Flora. The princess did not know how to interact with common folk and slaps him because she thought he kidnapped her sister. During their time at the academy, she avoided talking to him and she does not oppose to frame him for the outdoor drill. Rio meets with her at the banquet in the Garlac kingdom presenting the hero Satsuki, despite being watched by the Arbour faction, she secretly thanked him for saving her sister in Amande.

Personality
Christina thought she was a special being when she was young. Born as the first princess of Beltrum Kingdom, and the first in line of the throne. Blessed with the talent of study and magical talent. When she started her lesson, her tutors praises her as a genius. There is no setbacks and she would be called a genius no matter what she's doing. Effort wasn't hard for her and she thought effort was considered naturally for special beings who stands on top of the people. As she makes more effort and show more achievements, her parents will compliment her and her sister will respect her. She was better than others and became increasingly aware that she is more special than others. She thought she was a special being, that there isn't anything she can't do. There isn't anybody who is superior to her. Her ego was so enlarged by thinking like that.

Her encounter with Rio has changed her view. Rio was the first person who stare at her with cold looks, restrained her physical movements and made her afraid of people for the first time since she was born. Nobody has treated her roughly as she was the first princess and because everyone admired Christina. She was disappointed as it hurt her self-esteem. Up until now, she was proud to be special and she realized that she wasn't special but a very unreliable existence. As a result, Christina who grew up, realizes that she is no different from other human beings. She was born given the position of the first princess. It is the position that is special, not herself. It was when she went to the Royal Academy where it became more prominent. She can achieve exceptional results in all areas but she can only study and be clever. There is no outstanding talent, and she couldn't compare to a true genius, for example she does not rival Celia Claire in the field of magic.

When she saw Rio isolated in the academy, it brought indescribable discomfort as she sees the noble's son boasting about being special beings, it was like looking at her old self. The feeling of shame comes with discomfort. When she see Flora's sad face, she realize the reality of how powerless she is.

Christina has a serious personality, she's strict both to other people and to herself, she was raised as the first in line for the kingdom inheritance, because of that, she put the kingdom interest before everything, even herself, back when they falsely accused Rio, Christina also goes along with her father, because, for the kingdom, the noble are their allies, hence they are more important than the commoner, even if she know this is wrong, she still do it to the point Celia said that she killed her own heart to do that.

Despite this, she really love her own sister, as long she's safe and happy, it's alright even if it's resulted in some disadvantage to the kingdom.
