Plot

A 21st-century Japanese schoolgirl, Ayanokouji Shizuko, is mysteriously transported to 16th-century Japan. She survives by convincing one of the competing warlords—specifically, Oda Nobunaga—that she can assist his rise to power by improving agricultural production (by using her modern scientific knowledge, though she doesn't tell him that).

Many historical figures appear as supporting characters—Oda Nobunaga, Toyotomi Hideyoshi, Tokugawa Ieyasu, Takeda Shingen, and others—and many agricultural and industrial techniques are described, making the series a form of edutainment. As Shizoku's actions start to change history, the series becomes an alternate history.
