Alma Jinnai

She has overwhelming abilities and magical powers that can even rival Jewelina herself (it is later revealed that when Alma and Yuuma are together, Alma's powers actually exceed those of Jewelina despite Yuma being a completely normal and magic-less boy), but her magic has a terrible side effect as it drains away her life force and using it continuously would result in her death. It was revealed further that Alma was actually a girl after Opal used her Jewel Flash, letting Alma's black clothes change to a white dress.

She and Yuuma were once together but both of them were separated by Jewelina during childhood due to fear of awakening of the forbidden item, the Battest. Because she misunderstood the reason as to why she and Yuma were separated, Alma wants to use the item to take revenge on Jewelina, revive her mother, and let Yuma, Alma herself, and their mother live together again.

During the Grand Prix Arc, it is shown that both she and Diana survived and entered the Jewel Star Grand Prix under the Alias Laiya. In her new Identity, her black hair is now colored white after absorbing some of the Battest's powers and somehow defeated both Hilde and Topaz during the preliminaries of the competition. During the Semi-Finals, she defeated and injured both Leon and Dian, resulting to her win. The power of the Battest finally awakens inside her body during the finals as she plans on eliminating not just Jewelina, but also Akari as well. She finally redeemed herself after sealing the Battest and reviving Diana, Opal and Fealina.

By the OVA, she is now living alongside Fealina and Yuma in a family-run flower shop.
