#Opening Words
This book is a book for those who have never lived through the Sengoku era.
At the Konsei Reiyotan (混世霊妖譚) session table, while dice roll and swords clash, someone asks — just what kind of era was that, anyway? How did a samurai's day pass? An ashigaru (足軽) came from the fields — where did he return? What did the old woman do when a yoma entered the village in the night?
This volume does not answer these questions with numbers. What answers is the scene. The light falling on a samurai's tatami floor at dawn, the count of breaths an ashigaru takes as he grips his spear, the peach branch gripped in the hand of someone who has come face to face with a yoma — things like that.
Because this is a book to be read, do not consult it for checks. The rules are in the main co and ex volumes. This volume is writing to layer the world one stratum deeper behind those rules.

#Closing Words
#How to Read (Recommended)
- Read before session preparation, a little at a time — one or two chapters (章) at once. No need to read cover to cover.
- Do not consult during the session — it is not a check table. It breaks the flow.
- Read immediately after the session — good for extending the lingering mood of the scene just finished.
- No need to memorize after reading — if an impression remains, that is enough.
#Relationship with the co Main Edition
This volume is a supplement to co-02-lore (world-building). It is not duplication or replacement.
co-02-lore | fc02 this volume | |

| Style | Explanation | Narration · perspective |
| Scent · Law | Scent + Law together | Scent only |
