Haumea

is a member of the Ash Flame Chivalric Order.

Appearance
Haumea is a young woman with long hair that is usually tied. She has a tattoo on her left shoulder that resembles a sun and wears a crown-like visor that obscures her eyes. She wears a robe-like outfit that exposes her shoulders and a darkly coloured fabric under the lightly coloured outer layer.

Personality
While initially quiet and sombre, Haumea reveals herself to be childishly enthusiastic about her schemes and goals. In contrast to Sho's seriousness and pragmatic outlook, Haumea is both playful and sadistic. She is also brimming with confidence, dismissing concerns that she has revealed too much about the Ash Order's goals or she might be overwhelmed by multiple opponents. She also demonstrates this trait by refusing to answer Sho's questions because she is more powerful than him.

Abilities
Using her Ignition Ability, Haumea can create electric signals, which she can use to destroy electrical systems, as well as use it on people's nerves to subdue them. Haumea also possess Adolla Burst.

Background
When Sho was taken by the Preacher, Haumea is shown to already be by the Preacher's side.

Netherworld arc
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 a 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 responds saying that the Great Disaster that occurred 300 years ago failed to achieve something and that she plans on using the Adolla Burst to recreate the Disaster and that 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 Lieutenant 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, Captain 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.
