She is an orphan hush basset puppy who possesses the power of alchemy, as well as a love for chemistry and companionship. Before she met Lilac and Carol, Milla lived alone in the woods of the Valley Region, with her parents' whereabouts unknown. To cope with her loneliness, she carves a face into a tree stump and named it "Mr. Stumpy". One day, while playing with Mr. Stumpy near the ancient temple, Milla sees Lilac chasing after a Shang Mu truck, and follows her with the intent of meeting a dragon. Shortly after saving Carol, who was trapped in a cave following their fight with the Mantalith, she befriends her and Lilac, who invites her to live with them in their treehouse. Later that night, Milla overhears Lilac & Carol talking to Torque, offering to help him complete his mission, which was to prevent Lord Brevon from stealing the Kingdom Stone for his galactic conquest. Milla didn't know this at the time, but since she wanted to stay close to her newfound friends, she joins Lilac & Carol, and together, the newly formed Team Lilac set out to save Avalice from the brink of civil war. Following a 3-year time skip, Milla has grown more independent and lives in her own chemistry lab, where she trains her alchemy powers and makes potions to help her friends on their adventures. Soon, she will use her skills, old and new, in service of the Royal Magister, who has recruited Team Lilac to help defend Shang Tu from the remnants of Brevon's army, as well as discovering the origin of a new threat: Merga.
