A certain incident causes Tadashige Kasumikita, an ordinary company employee, to time-slip to the Sengoku period.

Lost and bewildered, Tadashige is rescued by the young Akechi Mitsuhide.

Tadashige, now living under Mitsuhide's care,

as he lives through the Sengoku period, is eventually taken into service by Nobunaga,

devising strategies relying on his faint historical knowledge,

and eventually establishes his position as Nobunaga's strategist.

Under the banner of "Tenka Fubu" (Unifying the Realm by Military Force), Nobunaga strives tirelessly to expand his power.

And Tadashige, who supports him.

As he forges deeper bonds with Sengoku heroes like Hideyoshi and Ieyasu,

he races against time to minimize tragedies such as the Burning of Mount Hiei and the Battle of Nagashima Ganshoji,

but will history permit such changes?

Oda Nobunaga, a formidable figure depicted as cruel, cold-hearted, and ruthless—

but was Nobunaga truly so ruthless?

Tadashige, resisting the corrective forces of history,

as he works alongside Nobunaga, aims to avert the Honnoji Incident,

and to unify the realm, conspires to quash any nascent rebellions... but...

And the letters Tadashige entrusted to Hideyoshi and Ieyasu,

and the contents of the letter left by his wife, Fuka...

Nobunaga's truth is now being revealed!
