Kenpuu Denki Berserk - episode 23 - 17 Mar, 1998

Back at the camp, everyone is forlorn because of Griffith's terrible condition. The Raiders ask Guts to take them along with him. Casca feels she must take care of Griffith, and tells Guts to leave. Delirious and horrified at what he has been reduced to, Griffith takes off in a wagon and crashes into the river. He finds his Behelit and unintentionally activates it, taking everyone present to the Astral Realm. (Source: Wikipedia)
