Mastema

The God of Law started a Conception event that began from Tokyo as Lucifer led an army of demons to stop him. The fallen angel succeeded in slaying the God of Law, stopping the Conception. All of the Amatsu deities, with the exception of Tsukuyomi, were annihilated in the war. The war left Tokyo as a barren wasteland—Da'at—and leaves the Throne of Creation empty, with gods and demons alike competing to take it. The God of Law cast a miracle known as the Shekinah Glory with his dying breath. Mastema fought on the God of Law's side during this conflict.

Bethel is a special worldwide organization that fights against demons that appear in the real world. They seek to stop the Qadištu from murdering innocents and resurrecting their goddess, Tiamat. Bethel has various branches, one of them located in Japan. That branch is headed by Hayao Koshimizu, the country's Prime Minister.

A plane of existence also known as the Netherworld and was once known as Tokyo, but has been named "Da'at" by demons. It became a wasteland courtesy of a war between the God of Law and Lucifer that ended with the fallen angel's victory 18 years ago. In his dying breath, the God of Law created the Shekinah Glory, a miracle that makes Tokyo appear as if it were normal.

The manifestation of God's dignity. Can strengthen Nahobino.

Magatsuhi affects the summoning, strength, and sustenance of demons, serving as a power medium. It's visualized as flowing red strands of energy, or a shining red liquid, if allowed to pool. It can be absorbed or gathered from the environment, but can be, and is often, harvested in greater quantities from humans—at the cost of their health or life.

A Nahobino is a demon who has regained their Knowledge of good and evil—typically though finding it in a human—and through that, their true godlike power.

"The Goddesses of Vengeance;" a group of female demons named after the Akkadian form of a feminine noun derived from a Semitic root meaning "holy" or "set apart." Their goal is to revive the primordial goddess of chaos, Tiamat, who was slain by the horned god.

After the war between the God of Law and Lucifer that took place eighteen years ago destroyed Tokyo, God's final act was this miracle, which makes Tokyo appear as if it were normal. It is not perfect, as demons often slip through the cracks into this plane of being.

A large, government funded university located in Shinagawa. Its medical research lab hosts Bethel Japan's headquarters. Due to its proximity to a rift occurring between the Shekinah Glory and Da'at, students who survived to return back to the false Tokyo were recruited by Bethel.

A Jōdo-shū Buddhist temple in Tokyo, Japan. It is the main temple of the Jōdo-shū ("Pure Land") Chinzei sect of Buddhism in the Kantō region. It is located in the Shiba neighborhood of Minato.

A high-ranking angel that is devoted to God and the is archangel that leads the forces of Bethel, as well as the angels' commander. Of the angels who followed Satan, Abdiel was the only one to reject the temptation to rebel against God, and instead received praise for returning to His side. Unlike her soldiers, she is suspicious of the concept of free will, though she respects humans and believes that God's law is ideal for them. Mastema distrusts her.

A queen of demons, she is called "the demon who dances on the roof," and is one of the four members of the Qadištu. Daughter of Lilith. Soft-spoken, and the least destructive of her sisters, though this stems out of a sense of pride in her skill rather than any actual sympathy for humanity. Has a dark sense of humor. Her skin is stark white, her sclera are bloodshot, and her irises are blood red. Her silver hair is curly and well-styled, with a small braid on either side of her temples. Her hands and feet are skeletal, and her joints like those of a ball-jointed doll. She wears a form-fitting, ankle-length evening dress with gold accents. The bodice of her dress is black, save for cutout diamonds in a chain running from the neckline to her waist, also edged in gold. She has an enormous pair of black wings, and seldom walks anywhere. Always has a parasol with a dizzying black and white pattern on its underside with her.

Princess of the Qlippoth and one of the four female demons that comprise the Qadištu. She is a personification of sin that eats the souls of the damned. Has the least regard for human life of any of her sisters. Takes the form of a humanoid woman with a white body covered in patterns of circles that flakes away from her hands, feet, and face from the mouth up which are instead black skin, and her hair is braided into sets of three over each side of her face and down her back. Her fingers and toes have long thin claws, there are a golden spiral on the back of each of her hands and top of her feet, and her eyes are black with shining white irises.

Khonsu strives to create a world of gladness, where everyone is treated equally.

Lilith is the leader of the Qadištu and first consort of Samael. Has a longstanding hatred of humanity, but hates the most recent Creator to take the Throne of Creation even more as the source of the world's flaws. She aims to revive Tiamat at any cost and establish a new order, hence the reason why she and the other members of the Qadištu have been indiscriminately attacking humans in Tokyo for their magatsuhi, gathering enough energy to accomplish this. Appears as a pale gray-skinned woman with waist-length, wavy, carnation pink hair, holding a lily in her left hand. Has the same functioning, downward-articulated, black feathered wings sprouting from her waist as her sisters do. Accompanied by a massive coral snake that is as long as she is tall, that serves as a familiar.

Naamah is an ancient and powerful demon, and one of the four female demons who make up the Qadištu. Charming, manipulative, lascivious, cruel, and self-interested. Good at justifying her actions, even if they are indisputably evil. Delights in mortal suffering. She appears as a vaguely humanoid composite of unnatural beauty and monstrousness, her left arm and right leg are sleek and unnaturally thin, her left shoulder and elbow tipped with sharp spikes that jut several inches out from her frame, covered in gilt. Her right leg ends in a slender spike rather than a foot. The right side of her face possesses the features of an incredibly attractive blonde woman with blue eyes and wearing red lipstick, while the left side is a grinning rictus of blackened skull, with whorls of gold and black arising from her brow, and the eye on that side of her face completely lidless, exposed, glowing with brilliant red light. A pair of black, feathered wings protrude from her shoulders and articulate downward, causing them to surround her waist.
