Description
Kinana is a member of the Fairy Tail Guild whose past is intertwined with the dark guild Oración Seis. Her background is unique, as she was originally a young girl transformed into a large, winged purple snake by a malevolent mage. For over a decade, she lived in this serpentine form under the name Cubellios, serving as the beloved pet and companion of Erik, a Dragon Slayer known as Cobra. During the events of the Oración Seis arc, Cubellios fought alongside her master, using her powerful venom to poison opponents like Erza Scarlet and her wings to provide aerial support. Following Cobra's defeat, the Fairy Tail Guild Master Makarov Dreyar discovered the snake was actually a cursed human and successfully broke the spell, restoring her to her original form.

Upon becoming human again, Kinana had no memories of her time as a snake. She told Makarov about a promise she had made with a special friend, that even if they were separated, he would ride a shooting star to return to her. Makarov allowed her to join Fairy Tail, primarily as an employee working as a waitress alongside Mirajane Strauss, partly to keep an eye on her in case her repressed memories resurfaced and caused her distress. Only a few members, including Makarov, Macao Conbolt, Wakaba Mine, and Mirajane, were aware of her secret past.

Kinana has a quiet, mild-mannered, and exceptionally kind personality. She is a diligent and hardworking individual, always eager to help around the guild. In her early days as a human, she had a verbal tic of adding kina to the end of her sentences, a habit she eventually dropped. Despite not initially being a fighter, she displays a courageous and selfless nature, once throwing rocks at enemies to protect her comrades, showing a willingness to risk her own safety even without proper combat magic. Over time, her memories as the snake Cubellios slowly begin to resurface, primarily in the form of a kind voice she hears in her head, which she later recognizes as Erik's.

Her connection to Erik is the central relationship of her life. Though she forgot him, the lingering promise drew her to seek him out after he escaped prison. Upon their reunion, Erik recognized her as his long-lost Cubellios, and the two reconnected. This relationship develops significantly, and by the year X793, they become a couple, with Kinana often visiting his home to help with chores. She is also good friends with fellow guild member Laki Olietta, who often accompanies and protects her.

Kinana's role in the story evolves from a background character and guild employee to a more active participant. During the seven-year gap following the Tenrou Island incident, she helps maintain the smaller, second Fairy Tail building, running its bar. When Fairy Tail disbands for a year of training, Kinana uses this time to learn magic, fulfilling her goal of becoming a full-fledged mage rather than just an employee. Upon the guild's revival, she takes a more active role in the final battle against the Alvarez Empire, fighting alongside her guildmates as a mage. Her development is marked by her transition from a cursed, amnesiac victim to a strong, independent woman who not only reclaims her past but also earns a place among Fairy Tail's magical ranks, eventually becoming one of the Twelve Starshield Knights.

Her notable abilities stem from her time as a serpent. As Cubellios, she could produce deadly poisons and transform her venom into a mist. After learning magic, Kinana regained this power, known as Poison Aroma, which allows her to generate and manipulate toxic gas in combat. She has also expressed a desire to learn Take Over magic, specifically the Animal Soul type, which would allow her to consciously transform into animals, perhaps even reclaiming her serpent form on her own terms.
