Wald

Wald Atmos is the ex-fiancé of Felmina and a member of the Tenth Demon Army.

Personality
As the Eldest Son and Heir to one of the highest ranking Noble Families within Demon Society, Wald was initially stated to completely embody the stereotypical prodigious/ideal son of nobility. Prior to Sophia's entry into the Demon Academy, Wald was stated to have been the one who completely dominated every field within the school, from academics, physical activities and martial combat, proving himself to be the most talented student within the academy. Causing him to develop a large ego and a strong sense of arrogance thanks to his achievements. And due to him having been born as a noble, Wald was also stated to have been highly adept in political maneuvering and social interaction/manipulation, with him having been stated to have the necessary cunning to analyze and manipulate the majority of the other students into becoming subservient to him without them noticing and establishing the hierarchy of the academy.

Wald himself greatly enjoyed the power he held over his peers and was stated to look down on all of them as inferior to himself. And due to his intelligence, Wald himself was stated to have completely masked all of the negative aspects of his personality perfectly from everyone around him under a kind, friendly persona.

However this all changed upon him falling in love with Sophia, while he initially disliked and even hated her due to her easily outdoing him in everything he tried to beat her in, Wald soon came to deeply admire and eventually love her due to his feelings of inferiority and competition becoming admiration and infatuation. Wald himself even came to even love Sophia's normally considered terrible personality traits, such as her sarcasm and lack of respect towards others she dislikes, with him commenting that he admired the way she was honest and vocal of the way she saw things and others and cared little of what others thought of her.

In fact, Wald's feelings for her had even gotten to the point that he was willing to abandon everyone and everything he had, his status as a noble, his position as the heir to his family, his fiancée and long time friend,Felmina and even his racial identity as a Demon, just to be with Sophia. In fact, when contemplating his actions of plotting against Felmina and then engineering her downfall from Demon High Society and getting her disown by her family after learning of her attempt to remove (kill) Sophia, Wald himself expressed absolutely no regrets nor guilt for his actions and even stated he would have gladly done it all over again and even sacrifice even more if needed for the sake of his love for Sophia.

Wald's deep love for Sophia, is seen to the point that he instinctively shielded her from Feirune's breath attack, showing that he was more than willing to sacrifice his own life for her.

Due to his love for Sophia, Wald has also shown to have developed a jealous side to himself as well. This is seen where he was jealous of Merazophis's close relationship with Sophia and desired to take her attention away from and keep it for himself.
