#Kageyama Castle 4-Mode Usage — One Castle, Four Times

Contents

Campaign Module. This is the usage guide for reusing the one stage fixed by 07-01 Kageyama Castle as four faces: siege, defense, Infiltration, and ruins. It creates no new maps or new rules; it repositions the same structures and zone properties by mode (which 3~7 zones are drawn today) and reinterprets them (what the same structure becomes in each mode). It only cites the 03~06 guides and 02-01·02-02, and does not redefine them — this is the demonstration of this volume's "one castle, four times."

#Scent — Same Gate, Four Gazes

Four people look at one otemon with different eyes.

• The attacker sees — a wall to break.
• The defender sees — the last line closed shut.
• The infiltrator sees — a shadow to slip around.
• The explorer sees — a collapsed tomb.

Same stone, four names. Kageyama Castle lives four times as one stage.

#§0 — How to Read This Document: Repositioning vs Reinterpretation

Scene Tool. This document only uses the stage from 07-01; it does not redefine it. No new numbers — only existing zone rules.

Two axes:

• Repositioning — choose the 3~7 zones to draw for today's scene from the full zone set in 07-01 (02-01 §Law 4 compression rule). Do not draw one castle on one map.
• Reinterpretation — turn on different zone properties and scene pressures for the same structure by mode (02-01 §Law 2·3). In siege, does the otemon block? In Infiltration, does it hide?

All four mode sections below use the same 4-slot frame (stage repositioning → structure reinterpretation → scenes/checks → mode shift).

---

#§1 — Structure ↔ 4-Mode Reinterpretation Master Table

Scene Tool. This unfolds the "GM hook (4 modes)" field from the 02-02 structure cards into one table (if a cell conflicts with the card, the card takes precedence).

---

#§2 — Mode 1: Siege — "How Do We Open It?"

• Stage repositioning. Narrow uphill path + otemon + wall-top watchtower + ninomaru yard + honmaru entrance. Example maps: co-05-06 03 castle gate pressure battle, 19 mountain temple defense, 21 fortress counterattack.
• Structure reinterpretation. otemon = narrow path Blockade Breakthrough (2d10+Courage ≥ 15) target / watchtower = high ground enemy firing position / honmaru = Core Zone boss lair. Fortress Defense = stone castle 15.
• Scenes/checks. Substitute the reconnaissance → pressure → Breakthrough → honmaru scenes from 03-01 and 03-02. Odd Target Numbers (reconnaissance Perception 11/13, Blockade Breakthrough fixed 15, negotiation 13).
• Mode shift. If stalled → Infiltration (secret passage bypass) / after occupation → defense (offense and defense reverse; now I defend it).

---

#§3 — Mode 2: Defense and Holdout — "How Many More Days Can It Hold?"

• Stage repositioning. Draw the same zones as §2, inverted into the defender's view — otemon=gate to close, watchtower=allied shooting/signals, mountain well and powder storehouse=supplies to defend, secret passage=double risk of collusion/escape.
• Structure reinterpretation. The same otemon shifts from siege's "Breakthrough target" into defense's Blockade point (assign Blockader, Defense +1) (02-02 otemon). Well=supply depot/contamination, storehouse=fire attack hazard.
• Scenes/checks. Substitute the closure, supply, reinforcement, sortie, search, public sentiment, and holdout-limit scenes from 04-01, plus the 04-02 holdout clock (tick=scene). co-03-10: public sentiment ≥7 militia +1(cohesion 4), ≤2 cohesion -1 — numbers as written in co.
• Mode shift. If the clock expires from a dry well or absent reinforcements → fall (siege side wins) / escape (leave by the Infiltration route).

§2 and §3 share the same map — this is the clearest proof of "repositioning."

---

#§4 — Mode 3: Infiltration — "What Do We Rescue Without Opening the Gate?"

• Stage repositioning. Use Outside Zone routes (secret passage, sewer, cliff, roof) + castle town (information zone) instead of frontal zones. Outside Zone entry uses co as written (shinobi 0 Energy, Infiltration Master 4 points 2 Energy, Lightness Skill Saint 5 points).
• Structure reinterpretation. The same watchtower becomes "surveillance route and guard-shift time"; well/kitchen become "infiltration route"; shrine becomes "Barrier evasion target." Cite forest/brush, narrow interior, and trap gimmicks.
• Scenes/checks. Substitute rumor → disguise → route → guard shift → Core Zone from 05-01, plus the 05-02 Infiltration maps. Among the 36 skills, only Infiltration, Perception, Negotiation, and Archery (if needed) — ranged action is Archery (not a separate gun skill), odd Target Numbers.
• Mode shift. On discovery, immediately shift to a siege/defense scene (reuse the maps from §2 and §3). If the seal was already broken → foreshadow ruins.

---

#§5 — Mode 4: Ruin Exploration — "What Remains After Collapse?"

• Stage repositioning. Change only the state of the same zones to ruins — otemon=blocked/collapsed gate, watchtower=collapse hazard, storehouse=yoma-tainted/abandoned masterwork, shadow gate below shrine=weakened seal. Demonstration of 07-01 "current state: ruins."
• Structure reinterpretation. Reposition as rockfall/collapse, Spiritual Taint (Fear Courage ≥ 11), spiritual vein, and Barrier. Spiritual elements reference fc08, but if absent, they are self-contained with co gimmicks + GM discretion.
• Scenes/checks. Substitute approach, search, blocked gate, earthbound spirit, yoma-tainted storehouse, forgotten passage from 06-01, plus 06-02 ruin d100. Exorcism and Perception odd Target Numbers, cleansing Exorcism ≥ 15.
• Mode shift. On seal collapse → yoma suppression battle (Core Zone=lord-grade lair) / on survivor or descendant discovery → escort/negotiation scene.

#§6 — Connecting 4 Modes in One Campaign

The four modes are not separate scenarios; they are one castle's timeline. Example route where one campaign visits Kageyama Castle four times:

1. Infiltration reconnaissance — border intelligence confirms the castle's weak points (dry well, secret passage). (On discovery → forced siege.)
2. Siege — attack the castle using the discovered weakness. (On stalemate → holdout reversal.)
3. Defense after occupation — defend the castle you seized against the counterattack. (If the clock expires → fall/escape.)
4. Ruin revisit years later — return to the collapsed castle to face the sealed shadow gate.

The same stones become a stage four times — that is how this volume's 18 documents create depth from a compact page count.

#§7 — Quick Reference Links

• Master table 1-line summary = "same structure, four meanings" (§1).
• 4-mode central questions: siege=how do we open it / defense=how many days can it hold / Infiltration=what do we rescue / ruins=what remains.
• The entry point to open during play is 99-01 quick reference.
