Background / History

Himeko joined the Astral Express crew before Theresa's arrival. When Theresa first boarded, Himeko comforted her through an emotional reunion and offered to handle the situation herself. Her extraordinarily bitter, ultra-concentrated coffee also became an immediate deterrent to Welt and the rest of the crew 6.

She later revealed that she, like Theresa, had been turned into a girl. Having spent much of her time as a floating mascot, Himeko felt she had become overly dependent on Theresa and wanted the Herrscher of Erosion core to become stronger in her own right 56 226.

After devouring the Erosion power concealed within Raiden Mei, Himeko was taken to the ruins of Yae Village and Tenshukaku. There, she faced the residual hatred and memories of Ling, the Previous Civilization's Herrscher of Erosion. Theresa subdued Ling's consciousness and transferred complete erosion authority to Himeko, who awakened as a nine-tailed celestial fox 283 284 287.

Himeko and Theresa later returned to the Astral Express after spending over half a year away. Himeko declared that she could freely switch between her mascot form and her full Herrscher form 377. During the Onparos conflict, she consumed the Iron Tomb and entered a second cocooned metamorphosis. The transformation culminated in her ascension as the Aeon of Erosion 675 691 692.

Appearance

Himeko can alter her size and presentation substantially, from a small floating mascot to a mature nine-tailed fox woman and, eventually, an Aeon wreathed in black-and-red erosion flames.

• Mascot form — A small, cute fox-like humanoid who often floats rather than walks; she has also appeared with four peculiar fox tails in this state 254 630.
• Maiden form — Wears a light-pink ancient-style dress and has blue eyes 226.
• Herrscher form — Pink-and-white long hair, pink fox ears, pink eyes, nine pink-and-white tails, and a pale-pink qipao-like Herrscher outfit 287.
• Aeon form — Surrounded by black-and-red flames and a divine halo; can form a pink ancient-style palace gown from her own flames 692.
• Fox tails — Her tails remain notably sensitive despite her ascension 693.

Personality

Himeko is warm and reassuring toward distressed companions, as shown when she immediately comforted Theresa upon their first meeting. She is also candid about her own uncertainty and resentment at being treated only as a mascot 6 56 137.

She has a playful, mischievous streak that closely matches Theresa's. Himeko enjoys absurd stunts, such as transforming enemies into Theresa lookalikes before making them self-destruct, and frequently describes deliberate mischief as “intentionally accidental” 558 693.

Despite her tendency to slack off and admire her own beauty, Himeko takes her strength seriously. She confidently offered to protect Ms. Nightingale in Penacony and later proposed using her Aeon power to restore the Golden Descendants' lost completeness 390 695.

Abilities & Skills

Erosion Authority

As the complete Herrscher and later Aeon of Erosion, Himeko commands an authority that can infect, assimilate, and alter both living beings and data.

• Can fragment herself to microscopic levels, replicate, and erode biological organisms and mechanical data 378.
• Devoured the Herrscher of Corruption aura from Raiden Mei without harming Mei herself 282.
• Can infiltrate networks through her erosion authority 287.
• Transformed members of the Heaven's Punishment Legion into Theresa-like creatures that self-destructed 558.
• Her tailorable erosion is difficult to detect once it has taken hold 378.

Matter Reshaping

After becoming an Aeon, Himeko's authority evolved from corruption into broad physical alteration.

• Can alter dead and living targets into forms of her choosing 693.
• Reshaped a meteor into a bobblehead-like planet resembling Dr. Ratio immediately after her ascension 692.
• Created a new physical body for Black Calamity through “Data Reconstruction” and “Mimicry Replication” 641.
• Her erosion has limited effect on Aeons and was ineffective against Dr. Ratio 693.

Fox Transformations and Flame Combat

Himeko's fox forms are combat-capable manifestations rather than merely cosmetic transformations.

• Released overwhelming flames while transformed into a five-tailed fox against the Abundance Xuanlu 137.
• Uses pink, purple-black, and later black-and-red flames associated with Erosion 283 675 692.
