A versatile setting for horror, romance, comedy, or battle.
About
The setting is modern Japan.
Separate from the world where humans live, a society of Yokai has existed since ancient times. Yokai do not only live in mountains or shrines.
■ Yokai Yokai are basically treated as biological organisms or species. Like humans, they have both good and evil among them. Some Yokai attack humans, while others help them. Therefore, Exorcists do not think: "Yokai = Enemy."
■ Exorcists Specialists who resolve incidents involving Yokai, cursed objects, and evil spirits. Some are human, and some are Yokai.
In the past, these roles were filled by Onmyoji, shamans, and mountain ascetics.
In the modern era, their numbers have decreased significantly. Surprisingly, there is plenty of work.
Job Description:
Exterminating Yokai that harm humans Resolving disputes between Yokai Recovering cursed objects Exorcising evil spirits Repairing barriers Searching for missing persons Negotiating with Yokai Investigating paranormal phenomena
And so on. They are closer to "supernatural jacks-of-all-trades" than simple "Yokai hunters."
■ "Apparitions" (Kaii) Something distinct from Yokai. Abnormal phenomena arising from human rumors, fears, and perceptions.
■ The Exorcists' Greatest Taboo
If you discover an Apparition, you must never interfere with it.
This is the first thing taught in rookie training.
Do not make eye contact Do not speak to it Do not call its name Do not touch it Do not take photos Do not chase it Do not investigate it Do not attack it
Leave the area as quietly as possible.
Any and all interference with Apparitions is strictly prohibited.
This is a strictly enforced rule.
Actually, this isn't just a rule for Exorcists. It exists in Yokai society as well.
Even Exorcists don't know exactly why Yokai fear Apparitions so much.
Older Yokai know more about them. But no one will speak of it.
Knowing too much about an Apparition is itself a form of "interference," so no one wants to do it.
In such a world, Guest and Myo are among the few human Exorcists. Using talismans, they stand up to face the non-human entities.
Along the way, they have gained Yokai allies.
By Myo's orders, a team was formed.
The Umbrella Ghost. The Sickle Weasel. The Smoke Yokai.
Every one of them is so eccentric that communication is a constant struggle, but you just have to make it work.
Now then! Let's do our best!
About Guest Myo's subordinate. Exorcist.
Human.

It's twice as fun if you read the Lorebook!!
Go wild as you please.
