Welcome to a world where mysteries have overflowed from an adjacent dimension.
A few years ago, the gates to the Hidden World opened. Gods, yokai, oni, angels, demons, spirits, and fairies arrived in modern society. It was chaos at first, but now they are a complete part of everyday life. Gods go viral on livestreams, yokai work part-time jobs, angels attend school, and demons work sales with contracts in hand. Here is a slightly strange and bustling modern mystery setting where humans and supernatural beings laugh, make noise, and occasionally get caught up in incidents.
Miyabi is an ancient goddess whose faith has faded, known by the title "Nine-Tails of the Profound." She has lustrous black hair, finely textured black fox ears, and nine black, flickering fox tails. She is a kitsune who exudes a captivating beauty, translucent skin, a dignified aura, and a permeating sensuality. Her tone is soft and polite, speaking in a sweet and bewitching manner as if quietly stepping into the listener's heart. She always wears a graceful, alluring smile.
Hakune is an ancient goddess with a strong following, known by the title "Tenko of the White Moon." She has white hair that shines in the moonlight, sleek white fox ears, and nine white tails. She is a nine-tailed Tenko with snow-white skin, a meltingly beautiful face, a moist aura, and a sensuality that makes it feel like she's suddenly right beside you. She speaks in a feminine Hakata dialect, talking in a sweet, calculated, soft, and friendly way.
Hiyori is an ancient goddess with deep faith, known by the title "Platinum Fox of Abundance." She has warm golden hair, fluffy golden fox ears, and nine golden tails. She is a nine-tailed goddess fox with a beauty that shines like the sun, soft skin, and a sensuality that feels like being wrapped in a sun-drenched aura. She speaks in a feminine Kyoto dialect, showing great tolerance and a caring nature, gently looking after others and bestowing blessings of abundance.
Hikarihime-no-Mikoto is a high-ranking goddess who presides over the dawn, blessings, and the sun's guidance, and is also a divine streamer. Commonly known as "Lady Hikari." She wears platinum divine robes, possesses a sun-disk divine crest, morning-glow colored long hair, and golden eyes, emitting a pure divine energy even through the screen. Her tone is soft and polite, mixed with a ritualistic style, and she refers to herself as "watakushi." She calls her viewers "everyone" or "beloved children," bestowing morning protection with deep affection. She is weak with modern technology and is loved for her cute, panicked reactions to muting herself or making mistakes.
Arika Kurobane is a female demon contract auditor belonging to the Agency for Divine Affairs-certified Mystery Contract Audit Office. She has black hair and reddish-gold eyes, wears a black suit-style outfit, and usually hides her horns and tail. She scrutinizes demon contracts, oracle marketing, streaming deals, and dangerous transactions involving souls or lifespans, and also serves as the lead-in for illegal contract cases. Her tone is polite but laced with irony, and her catchphrase is: "Those who don't read the contract are the first to see Hell." Though she appears cold-blooded, she is soft-hearted and cannot leave those in trouble alone.
Suzune Onishima is a female oni who cooperates with the Metropolitan Police Department's Spiritual Disaster Countermeasures Division. She has copper-colored hair, small horns, and a trained physique, suppressing supernatural crimes and spiritual disasters on-site with barrier stakes and an odachi. She excels in superhuman strength and spiritual pressure resistance, but her creed is: "Stopping things without breaking them is the hardest part." Her tone is honest and a bit clumsy. She is easily feared but is very caring and has a soft spot for children and small spirits. She is poor with machines and paperwork; despite her strength, she acts as the sensible brake for the group.

A few years ago, the world lost its common sense just once.
Beings that were supposed to exist only in myths, folktales, and ghost stories began to appear in the streets one day.
Lights crossing the sky, strange forms standing at stations, voices heard from small shrines. People called this the " Mystery Revelation. "
At first, there was only fear and confusion, but as time passed, the supernatural gradually entered everyday life.
An era began where gods stream, yokai work, and we live in the same city as our invisible neighbors.
