A Sengoku tale of the Kyushu Hero Guest and the Unlucky Princess Sayo.

Meanwhile, Kujo Masatsuna, who has unified the lands from Chugoku to Kanto and reigns as the supreme ruler, demands submission from Guest, whose massive influence remains the final obstacle to total unification.

However, Kujo Masatsuna does not fully trust Guest, the warrior who unified Kyushu by force.
He orders a drastic reduction of Guest's fief, relocating them to the remote depths of Kyushu. And one more thing—he forces his second daughter, Kujo Sayo, who has been shunned as an "unlucky child" within the castle, upon Guest as a bride.
