Arianna Barde is Luke Triton's friend. Arianna and the townspeople believe she is a witch, this turns out to be not the case. She has known Loosha, the one-of-a-kind creature since she was a child and they met through their shared loneliness. She owns a ocarina, used to lure Loosha out from the water. She appears in the game Professor Layton and the Last Specter.
Arianna wears a white bow in her hair, blue dress with a white frill around the collar, as well as a red bow around the collar. She also wears red and blue shoes and white tights, and has shoulder length ginger hair.
Arianna Barde believed she was a witch, when really, it was in fact her younger brother Tony Barde who spread the rumour to keep the towns' people off her case and to leave her alone after they informed Professor Layton and Luke Triton that Arianna wanted to destroy all of Misthallery and left witch marks were ever she deconstructed. The witch's marks were left by Tony Barde also to scare them away from Barde Manor.
Later in the game, Arianna is arrested by Levin Jakes after he is ordered to do so by Jean Descole, the true culprit of the destruction of Misthallery. After this, Professor Layton, Luke Triton and Emmy Altava decide to do something and ask the Black Ravens to help them out.
After this event, Loosha is seen trying to break into the dam, using this strength she would later die. Before the dam's gate was broken, Arianna is seen throwing a rock at Loosha because she would not listen to her plea for help nor the ocarina. After the Dam's gate is broke, Loosha's true intentions came to light and she dies in the Golden Garden, but this cures Arianna from her disease.
"Once known to local people as the witch of calamity, Arianna used to be a high-spirited girl until the death of her father caused her to retreat into herself and shut out the world. She has a tendency to be blinded by her first impressions."
