As the war for Japan rages on, the battle reaches the Royal Castle itself. Sarasa penetrates the castle's defenses to confront the traitorous Asagi. Shuri, wounded and crippled, pursues Sarasa even though the chase may kill him. Ageha descends into a labyrinth beneath the castle to stop a deadly mechanism designed to destroy them all. And King Ukon, now a pathetic, desperate shell of a ruler, grimly awaits Tatara's arrival!
