Haumea is a young woman with long pale-blonde hair that is usually tied into a bun, and some bangs falling to the side of her face. Most notably, she dons a golden crown-like visor around her face, obscuring all her facial features excluding her mouth. She has a tattoo on her left shoulder that resembles a reset button, inside of a sun. She wears a white and baggy onesie that is wrapped around her neck, and exposes the top of her arms and shoulders. She also wears a darkly coloured fabric under the white outer layer. She wears white sandal-like shoes that covers the majority of her feet, except her toes and heels. Just below her chest, is a red sun-like figure on the white robe.
While initially quiet and somewhat nonchalant, Haumea soon reveals herself to be playfully enthusiastic about her schemes and goals. Even though Shō is her superior, she is not afraid to treat him like a child and even use her abilities on him to get what she wants. She is also brimming with confidence, dismissing concerns that she has revealed too much about the Order's goals or she might be overwhelmed by multiple opponents. As shown when Arthur's plasma repelled her electric signal, Haumea can react very childishly, grunting and showing obvious annoyance.
Haumea has adapted to the Spontaneous Human Combustion and awakened her Ignition Ability as a Third Generation. She utilises her Third Generation as an Electric Shock User (電撃使う, Dengeki Tsukai). She can use these electric shocks to destroy electrical systems, and use electrical signals to manipulate people's nerves and control them, turning her opponents or random people into her puppets. She can also use these electrical signals to communicate with people from a distance, a technique she calls Radiohead, making her a valuable asset in missions where she is separated from her team as she is able to distribute information without being next to her accomplices. As the Second Pillar, Haumea also possesses Adolla Burst. She has demonstrated the ability to observe events normal humans cannot, including a battle happening at miraculous speeds and events happening within Adolla. She also seems to be able to control Demon Infernals to a degree. Both of these abilities appear to require a great amount of concentration. Haumea is able to land on the ground from a huge distance without doing harm to herself, which is questioned by Arthur to be accomplished by Haumea cushioning her fall will electric magnetism.
While her exact origins are unknown, Haumea has been shown have been by the Preacher's side for the majority of her life. 12 years ago, while Haumea was only 5 years old and accompanied by a 17 year old Charon, she was tasked by the Preacher with finding and abducting the new Adolla Burst host and Third Pillar, Shō Kusakabe. In order to successfully abduct their target, Haumea seemingly controls a newly created Demon Infernal to bring the infant Shō to them.
Netherworld arc Edit
Haumea startles Jonah in the Nether. The pair discuss that there are now three people with the Adolla Burst and that The Preacher would be happy. Haumea and Jonah are later seen observing the battle between Shinra and Shō. While the brothers clash at blistering speeds Jonah can't follow, Haumea is able to keep track of the tide of the battle. She also claims that the awakening of the Adolla Burst alongside an Adolla Link connected to the Preacher has created the Fourth Generation of Ignition Abilities.
As Shinra and Sho finally conclude their fight and embrace each other as family for the first time in 12 years, Sho suddenly stabs Shinra through the chest with his sword. However, Sho is shocked by what he has done and Shinra comforts him by telling that it isn't his fault. Sho turns to see Haumea, who claims that Sinra let his guard down.
Haumea tells Sho that Shinra's death would cause them problems so they must quickly leave in order to save his life. The exhausted Shinra asks her if she was the one how took Sho and why she wants the Adolla Burst. Haumea explains that the Great Disaster that occurred 250 years ago failed to achieve something and she plans to using the Adolla Burst to recreate the Disaster. Furthermore, the White Hoods have been using the Bugs to find people who have the Adolla Burst. Jonah chastises her for telling him so much, but she simply claims that nobody can stop her.
She then moves to take Shinra away, but Sho interferes and demands to know what happened 12 years ago. Haumea ignores his question and simply walks past him. Sho responds by attempting to activate Separate Universe, However, his ability doesn't activate and Haumea counters by using her own Ignition to force Sho under her control and he shambles away. Shinra once again demands answers, but Haumea responds by resting her foot on Sho's sword and pushing into further into Shinra's chest. Her sadism is interrupted by gunfire from Takehisa Hinawa and a sword-slash from Arthur, although Haumea is able to repel each attack.
Haumea attempts to use her power on Arthur, but it is ineffective against him. While Hinawa is surprised by this, she is more irritated by Arthur's use of plasma and that he's a boring foe. Before she can continue, she is attacked by Maki's Iron Owls, which she seemingly destroys by targeting their electronic components. Haumea attempts to control Hinawa, but her signal is blocked by Arthur's Excalibur, much to her displease. While she is distracted, Akitaru Ōbi almost crushes her with a column.
As Haumea stares down the whole of Company 8 an earthquake strikes, signalling to Haumea and Jonah that they have to leave. Haumea mockingly promises to meet Company 8 again, if they survive.
Special Fire Force Company 4 arc Edit
Haumea and Charon watch the events transparent within the Fire Force Training School from a rooftop. Haumea expresses glee as she controls members of Company 4 to provoke Shinra Kusakabe. Charon, unable to see what is occurring within the School relies on his partner to inform him about what is happening. The pair once again squabble, as Charon repeatedly asks for clarification about how Hitohashira Me is using the Adolla Link to control Shinra. Much to Haumea's fury.
After Arthur manages to break Shinra from Hitohashirame's grasp, the spectre tells him that another 'Pillar' will be born into the world. Haumea overhears this and loudly claims that the White Hoods will find the new, fifth user of the Adolla Burst, even if they have to battle against the Fire Force.
Fifth Pillar arc Edit
Using her eletric signals, Haumea is able to find Inka , the Fifth Pillar, and sends Charon's group to capture her. When Shinra interferes and attacks Charon, Haumea observes the conflict from a distant rooftop. She is eventually detected by Maki's rebuilt Iron Owls filying overhead. While commenting on the failure of the Fire Force, Haumea is interputed as Arthur attacks from above. While she is able to deflect his attacks, Arthur's plasma prevents Haumea's electricity from affecting him. Irritated, Haumea orders Charon to deal with Inka quickly so they can withdraw. As she engages Arthur, Haumea boasts that her side will be able to collect all 'Eight Pillars'.
