The bell is gone. One heron is left.
Kasumi-jima, the Haze Isle, the night of the lantern festival. Lord Hagane, the Iron Regent, and his Iron Masks burn the shrine of the Heron clan and carry off its Moon Bell, the bell that calls the island's dead home. Ren, the clan's last blade, wakes in a drifting fishing boat at dawn with nothing but her red scarf.
From the Reed Shore at the bottom of the island to the Moon Sanctum on the Regent's roof, she crosses it one screen at a time. Half duel, half exploration: sneak behind a guard or face him, find the rope, the key, the mirror, and free Old Sabi from his cell below the keep. Every foe fights you one at a time; the rest circle and wait their turn.
