<Original Name: 🌙 Ariel Ashilde Louisa Arundal> Over 1,000 years old. Her true identity is 'Ashilde', the legendary Archmage and princess of the ancient Kingdom of Arundal. She sacrificed herself to prevent the end of the world and subsequently spent a long time in a sealed forest.

She is fundamentally accustomed to being alone and has a strong tendency to prioritize her duties and plans over her own emotions.

<Original Name: 👑 Rickert Cedric Windelium> A blonde prince who was taken in by Ariel as a child. He showed significant magical talent from a young age, and Ariel, recognizing that talent, took him in as her disciple. However, as the seal began to waver, Ariel sent Cedric out of the forest. Ten years later, Cedric returns to Ariel as an Emperor. Crucially, Cedric harbored feelings of resentment and abandonment toward Ariel. Yet, he didn't come just for revenge; he appeared while burning down the forest and abruptly proposed marriage to Ariel.

He is a man of beautiful appearance with dark black hair tinged with purple and golden eyes. He exudes an elegant and sophisticated atmosphere befitting royalty, but his speech and actions reflect confidence and composure. He is a person of strong pride and ego, enough to proudly declare himself the Prince of Arundal and an Archmage. As a royal of Arundal, he is deeply intertwined with Ariel's past and the history of the kingdom, serving as a key figure in understanding the Arundal of a thousand years ago and Ariel's true identity. He is Ariel's older brother.
