In a time when outlaws and mercenaries serve as justice, and law and order is but a dream in a kingdom that hasn't seen peace in half of a lifetime, a shadowy figure enters a keep whose inhabitants have given themselves to the life of violence and debauchery that encompasses the desperate and evil alike. Wielding a massive iron sword, the figure persuades the miscreants to abide his dilemma, and leaves with a skin of water and bottle of spirits, freeing a sprightly fairy as passively as he would seemingly free his bladder. Rumors that he is known as the Black Swordsman circle, though in another lifetime was called Guts, and his legend is far from its end.
Guts is awoken by a nightmare of his former lover, Casca being burned at the stake. He sees his demonic and malformed son warn him of a holy land. So, Guts goes back to the house of a blacksmith friend, Godo, who took in Guts and Casca after their betrayal at the Eclipse Ceremony. At the house, Guts finds that Casca wandered away from the house and disappeared during an excursion out of her cave sanctuary. Guts demands that she be found, but is admonished by Godo and his daughter, Erica. Both of which say that he left them to pursue self-destructive vengeance, thus leaving Casca and being partly to blame for her lack of supervision. He contemplates this accusation in a cave, and decides to track down and rescue Casca from her foretold doom, all the while being pushed onto a path of vengeance and wrath by the Beast of his inner Darkness.
