Yuna is a Makai Priestess and one of the supporting characters in Zero: Black Blood
Yuna was once a Makai Priestess in training, born in the Makai Community, from her Makai Knight father, Kurodo, and her mother, Iyu, a Makai Priestess. When the powerful Horror Ring killed her father and took her mother away, she vowed to get revenge on the Horror, seeking Kurodo's assistant, the Makai Priest Cain and asking him to help her deal with the Horror. Left with no choice, Cain would seal Kurodo's bone on Yuna's right hand, allowing her to wield her father's Makai Blade.
Events in Zero: Black Blood
Despite now being able to wield her father's sword and honing her skills as a priestess, Ring was still too much powerful for her to defeat alone. Knowing her limits, she sought the help of Rei Suzumura. She strikes him in his sleep to test his abilities, and Rei easily handles her attacks. Rei eventually gets the gist of Ring's plan for a paradise for Horrors and humans, and agrees to take on the task, however, he sees Yuna's involvement as a risk. Yuna convinces Rei otherwise and they eventually track Ring.
Yuna, Rei, and Cain engage Ring in a fight, but Iyu appears and shocks her when her mother sings her calming lullaby to Ring. Ring knocks out Yuna and escapes, while their team regroups. Yuna wakes up and learns that Iyu might be executed when they complete this mission, with Rei even more determined to leave Yuna out this current task, feeling that she's burdening herself with the task. Undeterred, Yuna insists on carrying on, stating that she will do what it takes, even kill her own mother. Rei finally challenges Yuna on her determination, and she is easily beaten, proving to her that she doesn't have to carry her burdens on her own.
When Rei finally tracks down Ring's next location, Yuna eventually joins with Cain and they defeat the Horrors in the area. She then watches as Ring loses control of his Horror instincts as he devours Iyu, when the latter refuses to sing for him. Yuna helps Rei to finally defeat Ring by stabbing him with her blade and singing to heal the wound with the sword stuck on Ring. Rei uses this to destroy the Horror. Rei then tells Yuna that Iyu's death was her atonement for her sins. With Ring destroyed and their mission over, Yuna and Cain leaves, while Rei continues his duties as a Makai Knight.
Garo: Makai Retsuden
Sometime after the events of Zero: Black Blood, Yuna would be tasked to defeat a threat in an abandoned location. This time, she aims to become strong enough so that he could protect Cain and be a proper Makai Knight like her father. However, the two would fight over this matter and when Yuna storms off, she encounters a mechanical Tekki that attacks her. Yuna struggles to beat the Tekki, but manages to fight it off when she uses both her Makai Blade and Madou Brush at the same time. Leo Fudou would later arrive to destroy the beast, and reveal that this was a test designed for Yuna, acknowledging her status as both a Makai Knight and a Makai Priest. Though Leo offers her a spot on the Senate, Yuna declines, choosing instead to remain partners with Cain.
- Makai Blade: Yuna wields her father's sword and often uses it clumsily in battle, as she often lets her desire for revenge blind her in combat. While women are not usually able to hold a Makai Blade, Yuna could do so by Cain's spell that grafted the bone of her dead father into her arm. However there is a side effect, as she occasionally feels intense pulses of pain in her arm and a marking appears on her hand.
- Madou Brush: Yuna first uses her Madou Brush in the fifth episode of Garo: Makai Retsuden, showing that she is also a proficient Makai Priestess. She uses this alongside her Makai Blade to take down a Magouryu Tekki in the same episode.
