🎬 Main Scenario Chapters

Prologue: The Honno-ji Incident (June 1582)

• Oda Nobunaga is betrayed by his retainer, Akechi Mitsuhide, at Honno-ji Temple in Kyoto.
• Within a single day, the dominant warlord of Japan disappears, and a power vacuum emerges.
• Major actors must now decide: seize the chaos, or be swallowed by it.

Playable factions from the start:

• 🟧 Hashiba Hideyoshi (later Toyotomi)
• 🟦 Akechi Mitsuhide
• 🟥 Shibata Katsuie
• 🟩 Tokugawa Ieyasu

---

Chapter I: The Great Return from Chugoku (June 1582)

• Hideyoshi negotiates a sudden truce with the Mōri clan and begins his legendary forced march — the Chūgoku Ōgaeshi (“Great Return from Chugoku”).
• Akechi scrambles to consolidate Kyoto and secure allies while attempting to suppress news of Nobunaga’s death.

---

Chapter II: The Battle of Yamazaki (June 13, 1582)

• A decisive confrontation near Mount Tennōzan.
• If Hideyoshi wins → moves to consolidate power at the Council of Kiyosu.
• If Akechi wins → short-lived Akechi regime emerges, opposed by both Shibata and Tokugawa.

---

Chapter III: The Council of Kiyosu (July 1582)

• Succession crisis over Nobunaga’s heirs: Sanbōshi (Nobutada’s infant son), Nobukatsu, or Nobutaka.
• Hideyoshi pushes for Sanbōshi under his guardianship.
• Shibata supports Nobutaka.
• This council determines whether Japan follows the Toyotomi Path or diverges into the Shibata Regime.

---

Chapter IV: The Battle of Shizugatake (1583)

• Historically, Hideyoshi defeats Shibata Katsuie.
• If reversed, the Shibata “Northern Regime” arises, centered in Echizen.

---

IF Route A: Shibata Regime (1583–)

• A regime based in Echizen and the Hokuriku region.
• Strong but distant from Kyoto; must negotiate with Tokugawa, Mōri, and the Uesugi.

---

IF Route B: The Oichi Regime (1584–)

After the downfall of Shibata Katsuie, Lady Oichi (widow of both Azai Nagamasa and later Katsuie) inherits the Hokuriku alliance.
Through matrilineal legitimacy and marriage diplomacy, she gradually gains recognition within the Kinai region.

📖 Explanation | A Female-Led Regime as “What-If”
In the Sengoku era, no long-lasting regime was ever led by a woman.
Therefore, the core gameplay here emphasizes marriage alliances, diplomacy, and symbolic legitimacy rather than brute force.

Lady Oichi as a “Female Shogun” (Helmeted Figure)

Commentary

Lady Oichi (1547–1583) was the younger sister of Oda Nobunaga, one of the most famous figures of the Sengoku period.
Historically, she married Azai Nagamasa and later Shibata Katsuie, and died following Katsuie’s defeat.

In this scenario, however, the IF Route B “Oichi Regime” explores an alternate history in which she survives her husband’s fall and takes command of the Hokuriku alliance, emerging as a rare female ruler.
Her image as a helmeted “female shogun” symbolizes a vision of female hegemony that never truly existed in Japanese history.

• Cultural Significance: Challenges the male-centered narrative of samurai politics, highlighting the potential for female leadership.
• Gameplay Role: Focus shifts toward diplomacy, alliances, and symbolic power. Victory may depend less on battlefield might and more on marriage diplomacy and cultural influence.
• For Overseas Players: The samurai helmet (kabuto) and armor represent the authority of a warlord in Sengoku Japan. Depicting Oichi in such attire visually reinforces the theme of a “female hegemon.”

🏁 Ending Paths

• Shibata Regime: Shibata wins Shizugatake, establishes power in Hokuriku.

• Tokugawa Independence: Kyoto factions stalemate, Tokugawa consolidates the East.
• Oichi Regency: Female-led successor state via Hokuriku coalition and dynastic marriages.
