Kenpuu Denki Berserk - episode 24 - 24 Mar, 1998

The four archdemons of the God Hand awake and inform Griffith that he has been chosen to be their final member. For his baptism, Griffith must offer his friends as a sacrifice to the God Hand's Apostles. Griffith is shown visions of his past to convince him that the lives of his men are trivial in regard to the fulfillment of his dream. Guts climbs a mountain of flesh to try and stop Griffith from becoming a demon, but Griffith accepts the God Hand's offer. The entire Band of Hawk are branded as sacrificial offerings for the unborn child of darkness, Griffith. (Source: Wikipedia)
