She is usually attracting boys all the time because of the clothes she wears. She is very sporty, soccer being her favourite. She gets okay grades but fails a few subjects sometimes. Her new friends are Etsuko Mia and Adelina Schneider.
Reason why she moved to Japan
Lucy was forced to move to Japan from Australia with her parents since they really hated how Australia was turning out and decided they wanted a change of culture, so they moved to Japan. On the plane, Lucy had been thinking "Why Japan of all places? I can't even speak the language!" but found out on the plane that her parents could speak the language.
Etsuko Mia - Mia is Lucy's first friend in Japan. Lucy first speaks to Mia when she wanted to get to know her during class but got in trouble by the teacher and ended up in detention on her first day with Mia. They became friends during detention. She usually goes to Mia for help with stuff that Mia doesn't even know.
Adelina Schneider - Adelina is one of Lucy's Pretty Cure teammates. Lucy often teases Adelina with jokes about her having her head stuck in a book but she is usually going to Adelina for help with homework and studying.
Merry - Merry is Lucy's Pretty Cure mentor, as well as being Mia and Adelina's as well. Lucy gets a long with Merry but is usually being yelled at for goofing around during training.
