Berserk: Golden Age Arc III – The Advent (ベルセルク 黄金時代篇III 降臨 Beruseruku Ōgon Jidai-hen Surī Kōrin) was released on February 1, 2013 in Japan.
It has now been a year after Guts dueled Griffith to leave The Band of the Hawk. Upon learning the Hawks have been labeled outlaws in Midland, Guts returns to aid them in freeing Griffith from the Tower of Rebirth. However, they find out that Griffith is a broken man-barely alive and rendered a mute cripple after months of physical and mental torture. When Griffith tries to end his life upon realizing what he has reduced to, a solar eclipse occurs that draws him, Guts, Casca and their comrades into another dimension where they encounter the archdemons known as the God Hand. Told that his tribulations have been leading to this moment, Griffith is given a choice to be reborn as the final member of the God Hand and accepts while knowing his transition requires his allies being offered as sacrifices. In this hopeless battle with the God Hand’s monstrous horde of Apostles-former humans like Nosferatu Zodd-Guts’s attempt to rescue Griffith fails as the latter accepts the deal to make his dreams a reality. The result finds Guts and Casca escaping the sacrificial slaughter, while Griffith is reborn as Femto. Guts and Casca are spirited back to their world by the mysterious Skull Knight, but not without repercussions: Casca loses her sanity from the nightmarish ordeal she endured after being raped by Femto; and Guts losing his left forearm and right eye. A post-credits scene shows Guts beginning his journey to hunt down the Apostles and the God Hand so he can kill Griffith, setting the events of the 2016 Berserk anime.
