Kenpuu Denki Berserk - episode 12 - 23 Dec, 1997

Guts tends to Casca but she still resents him. She tells her story of how Griffith helped her save herself from being raped, and give her a choice in life so she followed him. She watched him pragmatically go with a pederast lord to earn money to create his army and fulfill his dream. When Guts came, she knew that she would not be Griffith's chosen friend.
