KeA has the appearance of a small young girl with amber eyes and light mint green hair.
Originally, she wears her hair down in wavy locks. She also wears a purple t-shirt, white jacket covered in badges, and orange skirt with a black hem, blue socks and leather shoes. Later, she ties her hair into two twin-tails and wears a yellow waistcoat type shirt with a black ruffle near the collar, a long purple jacket and white short shorts. She also wears yellow sneakers.
KeA has a bright an bubbly personality that makes almost everyone immediately fall in love with her and wish to protect her. This later accredited to her abilities, but she denies this is the case and it seems to be true even after losing her abilities. She is intuitively apt at everything she tries her hand at and volunteers her aid readily. She shows a great degree of selflessness, being willing to give up on her happiness to protect those she cares about if she believes that is the best path.
KeA is actually a homunculus cultivated as a reproduction of the Sept-Terrion of Mirage, Demiourgos, by the Crois family's lineage of alchemists. She was named KeA, derived from the idea that she would become the key to the origin of everything (all), "Key of A".
After creation, KeA has continuously slept for 500 years on the altar of the D∴G cult. The Cult, not knowing KeA's true purpose, was led into believing KeA was the daughter of the true Goddess, as opposed to Aidios. Following the Crois family's commands, however, Arios MacLaine was tasked with removing KeA from the altar and hiding her at the Schwarze Auction. It was KeA's decision as the Sept-Terrion of Zero that she wanted to be protected by Lloyd.
When KeA is found by Lloyd Bannings and the Special Support Section during the Schwarze Auction on Mishelam, which was organised and sponsored by politician Hartmann and mafia organisation Revache, she appears to have lost her memory. Her outspoken character and innocence makes her loved by everyone and she herself easily befriends all of the SSS's associates.
She turns out to be the centre of the D∴G cult's fanatical worship and they attempt to retake her by unleashing the full effects of the gnosis drugs, taking control over everyone that had taken it. The cult attacks the SSS to obtain KeA, so the SSS travel to their secret base to confront Joachim Guenter and put an end to the cult's designs.
After the cult incidents are resolved, KeA remains with the SSS and forms a lively part of their lives. One day she is taken and the SSS track her down to Mishelam where she had been taken by Arios, and several conspirators working for an independent Crossbell. It turns out the cult and all the major events in Crosbell's history had been engineered by the Crois Family as part of a thousand year long plan to resurrect their lost Sept-Terrion. KeA cooperates, seeing the situation as the best way to protect those she loves. She powers up three Aion units and Crossbell now has the power it needs to make a claim for its sovereignty under the leadership of Dieter Crois.
Upon KeA's completion as the Sept-Terrion of Zero, she had not only inherited governance over mirage, but the two other higher elements - time and space - as well. This means that KeA possessed a terrifying power that allowed her to read and overwrite past, present and future alike. Mariabell Crois reveals that KeA had already used this ability during the SSS's fight against Joachim Guenter in which the team was originally killed, as well as unconsciously causing every being she interacted with to love her, including the members of the SSS. The latter reveal caused KeA to merge with the Azure Tree and become the Azure Demiourgos.
After the Special Support Section beat the Azure Demiourgos and released KeA from the spell, she began to follow the footsteps of the original Demiourgos by wishing herself out of existence. Lloyd, however, broke into KeA's inner world and persuaded her to return to her family at the SSS. This resulted in KeA losing her powers and becoming an ordinary girl.
She assumed the surname Bannings during the imperial occupation of Crossbell. She is trapped with Lloyd Bannings in Operation Birdcage and isn't seen until the operation is lifted. Rean espies her waving as he leaves Crosbell on the Derfflinger.
After the Great Twilight, KeA joins Lloyd, Elie and Estelle, Joshua and Renne Bright in a mission to retrieve information on what happened in Erebonia from The Orchis Tower's Mystic core/Thaumaturgical sector's database. KeA helps Renne hack into it whilst the others hold off Mariabell, Black Alberich and Claire Rieveldt. Successful, they then flee.
KeA appears in the swamps with the others to come to the aid of new Class VII against the various forces set against them. Afterwards, KeA leaves Crossbell and Travels to Eryn where she remains until the operation to free Rean Schwarzer from the Black Workshop is underway.
KeA makes appearances at the multi-nation conference onboard the Pantagruel to discuss Mille Mirage, the mission to deactivate the barrier in Crossbell so they can get to the Stella Shrine, the Spirit world quest involving Elie's mother and the final night at Mishelam before the Great War. During the final battles, she accompanies the SSS to one of the fake Salt pales and provides support with her remote orders.
KeA is present at the SSS's efforts to liberate Crossbell from the remnants of Rufus's personal guard,and assists the SSS in their operations afterward in the lead up to the re-independence signing ceremony. During the takeover by Supreme Leader Rufus, KeA begins to get an inklin of what is going on. After everyone is split up, KeA is rescued from the Sun Fort where she was being held by Cao Lee, Garcia Rossi and Ilya Platiere.
KeA is present with Lloyd's group right up to the final battle with Elysium in Reverse Babel where she helps to shut the system down.
|(Former) Zero Child|
|A girl created to be the Sept-Terrion of Zero. Her divine powers have mostly vanished, but she can still see how everything is connected.|
Made by Crois alchemists in a similar way to Altina. While this shows what their foe is capable of, it also let the two girls bond.
KeA tried to predict how things will develop, but all she could say was that everything is riding on the outcome of this final battle.
