From Esthétique:

Akechi Mitsuhide, who resided under the roof of Saitou Dousan, hid himself in Nobunaga Oda's palace Owari under the guise of a marriage with Dousan's daughter, Nohime.

Before long, that fated meeting was bound to create a great change...

Honnou Temple burns with the fires of love and hatred. A dazzling story of love and romance in a country ridden by civil war!
