#Yoma Scenes and d100 Tools

Contents

A kaidan scene begins not with "what comes out" but with "what turns strange first."

#Opening Fragment - The Black Table

The children of the village school made a table on every rainy day.

In the first column they wrote a place. Well, bridge, storehouse, grave, castle gate, mountain path. In the second column they wrote a sound. Weeping, laughter, drum, bell, water sound, footsteps that should not be there. In the third column they wrote a thing not to do. Do not look back, do not count, do not answer, do not say a name.

It was a game.

But one day, after a child filled in all three columns, he did not come home. On the table it was written:

Storehouse. Laughter. Do not count.

After that the adults could not burn the table. Each time they tried to burn it, one more child's laughter rose inside the storehouse.

#Scent - Three Columns Are Enough to Raise a Kaidan

A kaidan works even without a complicated setup. With only a place, a sign, and a taboo, you can begin the first scene. Then add the yoma's name, the Gate of the Spirit Realm, and a faction's involvement, and it becomes a campaign hook.

#Law - Quick Assembly Procedure

Decide the place.
Decide the strange sign.
Decide the taboo.
Decide the yoma's food.
Decide the relationship with the gate.
Decide one faction that will intervene.

01-05	From inside the well comes the name of a living person, not a dead one.
06-10	The armor in a ruined castle turns to a different direction each night.
11-15	A waymark on the mountain path points to the same spot three times.
16-20	A name tag floated down the river burns without getting wet.
21-25	The old vessels in the storehouse are set out one more than the number of guests.
26-30	The shadow under the bridge greets you before the person does.
31-35	A drum sounds from a battlefield grave, but there is no drum.
36-40	The last verse of the song the children sing changes every day.
41-45	Each time the temple bell rings, one of the village dogs loses its voice.
46-50	Count the footwear before the mountain gate and one is always missing.
51-55	In every house that bought a fox mask from the market, they have the same dream.
56-60	On a rainy night, knock the door handle three times and the answer comes not from inside but from behind you.
61-65	The procession inside the old folding screen steps forward one pace a day.
66-70	A headless horse outside the castle gate searches for its master.

76-80	A discarded doll grows larger in proportion to its owner's age.
81-85	At the end of the tunnel there is the same village once more.
86-90	Writing erased from the notice board is pasted on the door like a talisman the next day.
91-95	A corridor inside a video erases one room of the actual house.
96-00	A kaidan no one has ever made is already in everyone's memory.

#Operation - The Truth Level of Clues

Truth Level	Use
True	Points to the yoma's weakness or taboo.
Half True	The direction is right but the details are wrong.
False	Someone spread it. It may be the trace of a human faction rather than the yoma.
Dangerous Truth	A correct statement, but following it as is carries a heavy cost.

Not all kaidan clues need to be real. But if every clue is false, the incident becomes unfair. Of three clues, always keep one true.
