#107: The Ink-Stained Estate of Oiwa | The Walls Remember a Murder | A 5e Feudal Japanese Horror One-Shot for Small Groups
The house is beautiful before it is deadly. Three months ago the lord of the Estate of Black Birch murdered his wife and hid her beneath the floor. Her spirit has been redecorating in ink and hair ever since — and she can smell a lie.
Lord Ashida told the world that Oiwa ran away. The estate believed him. The walls did not. Her vengeful spirit has rewritten the manor into a living ghost story: ink seeps through the paper screens, corridors shift when no one is watching, and her hair fills the koi pond like black silk.

Now the steward has hired your table — masterless wanderers with no stake in the family's shame — to descend into the estate and recover the ancestral blade before the house sinks into the underworld. But that blade is the weapon that killed her. Oiwa knows exactly why you have come, and she is done being lied to.
A complete fifth-edition adventure you can run tonight, cold, with zero preparation.
What's Inside
- A full 2–3 hour one-shot for 2–3 players at levels 2–3 — zero prep, ever
- Twenty named scenes across four acts, with a branching second act: creep through the lord's study or fight through the burning servants' quarters, both leading down to the Cellar of Faces
- The Grudge Track — a visible 0–10 measure of the ghost's rage that climbs no matter how carefully your table plays, reshapes the house around you, and empowers Oiwa's final form
- Five paper talismans and one broken comb: a tight resource economy where every ward you burn is a real decision
- A three-phase boss with a weak point, a secret, and a mercy — tuned so it never one-shots a hero and stays winnable by any two of the pregens, even an all-martial pair
- Twenty-three read-aloud blocks, written to be read cold at the table
- Six SRD 5.1 stat blocks and fully written NPCs, from paper shikigami to the onryo herself
- Four ready-made characters — any two form a viable party, no filler seats
- Five battle maps, six opening hooks, six off-script contingencies, and five campaign seeds
Three endings. No right one.
When Oiwa's anger finally breaks, the choice belongs to your table: shatter her comb and lay her to rest, bind her spirit into the blade and carry her power at a cost, or kneel and give her the apology she was owed in life. Each ending is fully written, with consequences, an epilogue, and a hook into whatever you run next. Groups argue about this one on the drive home.
A ghost worth pitying.
Oiwa is not a monster to be cleared off a map. She is a murdered woman, and the house is not so much haunted as grieving. This is culturally rooted kaidan horror in the tradition of the classic Japanese ghost story — restrained, atmospheric, and human. The estate is lovely before it is lethal, and it is always, quietly, keeping score of how your party behaves.
Built for the table you actually have
Most published adventures assume four to six players and a Game Master with a free weekend. This one is built for two or three friends and one evening. Every fight is tuned for a small party, every revelation has three separate ways in, and every scene has a written fallback for the moment your players do something nobody planned for.
The maps are a suggestion, not a requirement. Run it on a grid, a whiteboard, or entirely in the theatre of the mind.
What you need
The core fifth-edition rules and two to three friends. Everything else — characters, creatures, maps, and the whole haunted night — is in this book.
Perfect For
- Game Masters who want a complete horror session without a week of prep
- Small tables — two or three players, no need to fill empty chairs
- Anyone who loves a tragic villain and a choice with no clean answer
The walls remember. The ink never dries.
