A beautiful princess of Caldea who is also a witch of immeasurable power, and the younger sister of Diana, Queen of Chess Pieces (the former princess of Caldia). She is the step-aunt of Snow and thus, she bears the responsibility to put a permanent rest to Diana's actions in accordance to the laws of their birthplace, the magic kingdom Caldea. She is first to appear walking up to Ginta. Since she saw the great strength of Ginta, she asked him to help her get ÄRM. When he refused, she offered up a Weapon ÄRM that was completely useless. Ginta agreed not knowing a thing about the ÄRM, so they enter the cave of where the ÄRM is sealed. Later, when they arrive at the ÄRM's location they have to face a powerful Guardian ÄRM, Brikkin. As Dorothy fights it with her Guardian ÄRM Flying Leo, Ginta gets the ÄRM who calls himself Babbo, then Flying Leo breaks, and so with Babbo he beats the Guardian Brikkin. Later they argue over Babbo to the point when Dorothy tried and failed to pick up Babbo because it was to heavy thus Ginta got Babbo. Disappointed she flew away on the Weapon ÄRM Zephiroth's Broom. Dorothy has an interest in stealing any uncommon ÄRMs she comes across (which is also her other duty on Kaldea's behalf), heaping up into a wide variety for her collection, but she seems to prefer Guardian ÄRMs and Wind-themed ÄRMs in battle. Dorothy's moods can vary from the sweet, kind-hearted girl to the pitiless, cruel fighter who could kill her enemies without any second thought. She also has a notably large crush on Ginta, leading her to smother him with attention, much to Princess Snow's chagrin.
