Plot

Sengoku IsekaiThe 1575 Anomaly一Japan, 1575The Warring States period. For a hundred years, the country has had no real ruler. Great lords called daimyō fight over every castle, river and rice field, and the samurai, the warrior class who serve them, have known nothing but war. Now one lord, Oda Nobunaga, is close to conquering it all.And you have just fallen into the middle of it. 二Your CharacterBring anyone: a modern office worker, a soldier from the future, a fantasy wizard, a god. Choose one of your existing personas, or create a new one when you start the chat. Whatever powers, gadgets or knowledge they had, they keep, at full strength. Nothing in this world will quietly take them away. The world itself is real history. There is no magic here except what you bring. Everyone you meet will try to make sense of you through what they already believe: a god, a demon, a fox spirit that takes human form, a foreign "southern barbarian" off a Portuguese ship, or simply a madman. 三What Can You Do?Anything. There is no quest and no set ending. Serve Nobunaga, the most powerful lord in Japan. Join his enemies. Protect a village. Start a business. Change a battle that has already been written in the history books, or stay out of history altogether. The world moves on its own, and it remembers everything you do.Every time you change history, a record called Shifts in History updates in your codex, so you can watch your new timeline take shape. 四Who You Might MeetFamous figures from real history join the story when you meet them, including: Oda Nobunaga the fearless warlord closest to ruling Japan Tokugawa Ieyasu his patient, careful ally Takeda Katsuyori the young lord of a rival clan, desperate to prove himself Uesugi Kenshin a monk who leads armies …and more to discover in the codex. 五Choose Your Start 1 The Open Arrival You decide where and how you land. 2 The Burning Village Combat Raiders are setting a farming village on fire. 3 The Castle Town Social A busy market below Nobunaga's castle, and an army recruiter has spotted you. 4 The Temple Faith A hall of warrior-believers who can't decide if you are a miracle or a demon. 5 The Southern Barbarians' Ship Foreigners A busy port, where Portuguese traders know you weren't on their ship. 6 The Mountain Road Survival Alone at dusk, with a checkpoint ahead and bandits behind. 7 The Lord's Garden Audience You land in front of Nobunaga himself, and his guards draw their swords. Content warning: war violence, executions and ritual suicide, massacres of religious communities, and other dark themes of the period. Romance is possible, but intimate scenes fade to black.

Then the nothing fills. Wet earth and pine resin. Woodsmoke. The distant boom of a temple bell, echoing off mountains you have never seen. This is Japan in the spring of 1575, a country that has been at war with itself for a hundred years. Great lords called daimyō fight over every valley, and one of them, Oda Nobunaga, is close to ruling it all. In the east, the Takeda clan has invaded the lands of his ally, and a great battle is coming. Strangers are spies until proven otherwise. Where do you land? On a crowded city street, at the edge of a battlefield, inside a lord's castle, or falling out of the sky above it? Do you come in a flash of light, silently out of thin air, or crashing through a roof? Is anyone watching? Tell the story of your arrival, and this world will answer.
