Mim's Trust Master reward is the Fairy's Scrunchie.
3★ - No. 0913: A magical creature called a "sprite" that was known to dwell in the forests long ago. Although sprites like Mim are only ever seen in fairy-tales nowadays, even scholars who specialize in the subject have yet to agree on whether they ever existed in the first place. However, the personality of this particular sprite who reappeared as a vision of her former self closely resembles that of the lovable scatterbrains so often heard from in fables.4★ - No. 0914: A sprite from times past who dwelled in a small village within the forest with other magical creatures. Recent discoveries have found that Mim and many others like her lost their homes at the hands of humans, who sought to further expand their territories. Many believe that this traumatic experience is what caused her to return as a vision, but she doesn't seem to pay much mind to it as she flies around happily looking for someone dear to her.5★ - No. 0915: A sprite from ancient times who is a childhood friend of Timothy's, another sprite who fought to protect his village. Sprites such as Mim have been said to be blessed with amazing longevity, usually making them much older than what their youthful appearance tends to indicate, and their emotions that much more intense. Due to this her vision has been imprinted with a great desire to find her disoriented childhood friend in the forest, so now she makes quite the ruckus as she flies around looking for him.Entries for different versions of Wado.
