Juliana is known for her lively, cheerful personality that lets her get along with anyone. Playful and mischievous by nature, she has a knack for finding fun in every situation—sometimes even at the expense of others. Her teasing sense of humor, especially toward her younger twin-brother, Florian, often earns her laughs and eye-rolls in equal measure.
A true thrill-seeker, Juliana loves adventures and Pokémon battles, always chasing excitement wherever she goes. Brave and daring, she never hesitates to take risks—something that often contrasts with her more cautious twin brother, Florian. Many say she has a “pure, clean heart,” though her confidence and constant need to be in the spotlight sometimes overshadow Florian, unintentionally leaving him in her shadow.
Despite her impulsive and carefree streak, Juliana is deeply affectionate and responsible when it comes to her Pokémon partner, Koraidon. The two share a wild bond, often seen laughing and wrestling together. Even when Koraidon barrels into her playfully, Juliana simply laughs it off—unbothered, unfazed, and full of life.
