From a young age, she was a genius in everything she undertook, from academics to physical abilities to her own magical feats.

Upon becoming a student of Kyomon Academy, Celiska quickly spent the first term rising through the ranks to become the first-ranked fighter as well as student council president, a position she inherited from the previous president who had graduated. She also became fast friends with the blind Aika Asagi and the caged Shiori Akizuki, making them into her vice-president and one of her secretaries, respectively. The three of them were one clique that couldn't be separated. Upon finishing the first term and returning to her homeland, her father revealed that she was engaged to the Archduke of Ustor, Lukas von Stuttgart. Initially against it, Celiska quickly accepted the affair as she was very much a daddy's girl.
