Angra Mainyu/CCC: All the World's Desire (この世全ての欲, Kono Yo Subete no Yoka?) is the anti-planetary Noble Phantasm of the demon-transformed Kiara Sessyoin. She was reborn into the earth mother, accepting all the desires of humanity, but also becoming a sacrifice to those desires. It is an Authority allowing her to gain the greatest of sensations and growth by offering her body to and embracing all life left on Earth from humans to animals and plants. This grants her the greatest possible mastery of the lifeforms' senses and carnality. It is the "most heinous" of Noble Phantasms, utilizing the Earth for masturbation.
The ability turns her into the floodgates of all the desires of humanity, allowing her to usher the souls of people into her body by utilizing the Code Cast Banshokuyuutai. She creates a vortex of pleasure that melts sapient beings, subliming their lives in a brief instant. It is the birth of an ephemeral but eternal Land of Bliss. It works on any sapient being without exception, no matter how different the structure of intelligence, making it a Noble Phantasm that is not limited to only the Earth. The performance, presentation, and scale of the attack are large due to Kiara being an existence close to Saver, a Bodhisattva. Her existence is similar to a certain man-made demon who had once been demonized and celebrated as a sacrifice to prove the evil of mankind. It has a special effect that deals more damage in certain conditions, increasing if used on a member of the opposite sex from the user and dealing more damage the higher the intelligence of the target. Archer would have taken the least damage of Hakuno Kishinami's Servants, while Gilgamesh would have taken the most.

All the World's Desire [Noble Phantasm]
This is the anti-planetary Noble Phantasm Kiara gains after her reincarnation.
Angra Mainyu is the most self-serving heinous Noble Phantasm of them all where Kiara uses the world to masturbate.
Kiara offers her body in a sexual manner to all living things on Earth, including humans, animals, and plants. By completely accepting all people as is she gains the greatest possible mastery over their senses and carnality.
This Noble Phantasm is derided for being demonic and it’s similar to the living sacrifices used for certain artificial magic ceremonies used the past in order to prove the evil of humans.
It is a vortex of pleasure that melts all sentient beings, and digests their “life” in an instant. While in reality it all happens in an instant, but it feels like an eternity of pleasure.
Regardless of how different the structure of a beings intelligence may be, this vortex affects all without exception. It is not a Noble Phantasm that is limited to affect only those on Earth.
The damage increases if certain conditions are met.
If the target is of the opposite sex, the damage increases.
The more intelligent a being is, the more damage it does.
As far as the setting and lore are concerned, the Servant who would be hit with the least damage would be Archer, and Gilgamesh would be damaged the most.
The reason why this attack’s power, visuals, and scale are so huge is because reincarnated Kiara is a being similar to Saver.
People who devote their life to bringing salvation to Sattvas (living things) are referred to as Bodhisattvas. People who have attained moksha (libertation/release) and become Buddhas are also Bodhisattvas. A Bodhisattva is a god of universe scale and power, and can easily manage things on the scale of the Solar System.
Buddhism has a sense of scale of the universe that stands out from that of other religions. There are concepts like Nayuta (1060) and “The Infinitely Vast Number” (1068) which were created to represent the scale and size of a Buddha.
The entire universe is the domain of a Buddha. In Buddhism the universe in considered to be made up of three billion solar systems (a great trichiliocosm). A galaxy comprises of 3000 solar systems (a small trichiliocosm), and 1000 small trichiliocosms make up a trichiliocosm.
This actually aligns with the real scale of galaxies, galaxy clusters, and super clusters.
India had this stuff figured out over 2000 years ago? Holy crap!
In the initial design phase of the game I submitted some paperwork describing this Noble Phantasm. I thought there would be no way that this gets by CERO untouched, but surprisingly enough it did.
I still have no idea how this was able to make it past them.

Fate/Extra CCC encyclopedia - All the World's Desire (Angra Mainu)/CCC
The Noble Phantasm of the demon-transformed Sesshouin Kiara.
Sesshouin Kiara absorbed two Alter Egos and transformed into a demon through the mooncell.
While she was reborn into the earth mother, accepting all the desires of humanity, she was also at the same time a sacrifice to all the desires of humanity.
Her existence is similar to a certain man-made demon who had once been demonized and celebrated as a sacrifice to prove the evil of mankind.
Turning into the floodgates of all the desires of humanity, she ushers the souls of people into her body by Code Cast Banshokuyuutai and creates a whirl of billions of pleasure.
The whirl of pleasure melts sapient beings and transforms their lives into the sublime in the twinkling of an eye.
It is the birth of an ephemeral but eternal Land of Bliss.
This whirl of pleasure works on any sapient being without exception, no matter how different the structure of their intelligence is.
This is not a noble phantasm limited to the Earth.
