is a survivor of the Great Cataclysm. Possessing an Adolla Burst, she powers Tokyo and is referred to as the.

Appearance
Amaterasu appears as a naked woman of slender yet curvy build with shoulder-length blonde hair, blue eyes who is regarded as resembling her counterpart Iris in appearance.

Personality
As shown when she took control of Shinra, Amaterasu showed very manipulative behavior. She used his resentment towards people branding him as a Devil, his anger at the Demon that destroyed his family and his confused emotions about the Infernal's true identity to control him. Amaterasu's palpable hatred of humanity is felt by Shinra and noted by Haumea. While she controlled Shinra, Amaterasu tried to provoke him into burning and killing everything and everyone in their path. It's implied her intense hatred of mankind is the result of being forcibly used for centuries as a power source to restart civilization and start the Tokyo Empire after her Adolla Burst was awakened by the Evangelist.

Background
Soon after the Great Cataclysm, Amaterasu was found by Yona. Intending to use her Adolla Burst to make civilization bloom again, he encased her in a container and delivered her to Raffles Smith's group, leading them to use her as nourishment for the people and generating power for the Eternity-Style Thermal Power Generation "Amaterasu".

Abilities
As the First Pillar, Amaterasu most likely possesses an Ignition Ability and an Adolla Burst. Shinra Kusakabe suspects and later confirms that she is indeed the power source of the Amaterasu that powers the entirety of the Tokyo Empire, further alluding to her immense power. Like the Woman in Black within the Tabernacle, she is able to appear before other Adolla Burst users through the Adolla Link.
