Kya's charm

Kaiya's Jewel Charm is oval-shaped, mostly colored teal along with several light blue kyanites and white decor.


According to the official website, Kaiya is usually described as elegant and quite prideful of herself.

In Jewelpet Twinkle☆, she can be seen as quite a snob and extremely loyal to her partner, Marianne Grand Maniel Chocola Julliangeli.


As the Jewelpet of Decisiveness, Kaiya's magic allows humans to make decisions without hesitation or doubts. Also being the Jewelpet of Independence, her power can free humans from anyone's control and give them the courage to leave their masters and go on their own path. In Jewelpet, Kaiya wields the power of the latter, while in Jewelpet Twinkle☆ she has the former.
