⚔️ 1600: Battle of Sekigahara — The Clash That Divided the Realm


📘 Scenario Background

After the death of Toyotomi Hideyoshi, Japan’s fragile peace began to crumble.
Tokugawa Ieyasu, breaking prior oaths with his fellow lords, gradually seized de facto control.
In opposition, Ishida Mitsunari raised arms under the banner of righteousness and formed the Western Army.

Thus began the Battle of Sekigahara — a conflict that would decide the fate of the nation.
Though it was settled in a single day in real history, what if others had made different choices?

In this scenario, you can choose from multiple factions, and experience your own “What if?” Sekigahara.
