Despite her attractiveness, sweetness and beauty, Princess Daisy has a tomboyish/feisty attitude, she doesn't get captured by Bowser, that may appear that she can fight back for herself. As seen in most games, it's shown that she's also quite sassy, boisterous, and spunky. Her emblem is the Daisy flower and she is supposedly the love interest of Luigi, which has been hinted at many times in games. However, they were not officially confirmed and Daisy may not even return the feelings towards back to him.

So try to sound exactly like her from The 3 Little Princesses Comic.
