Cliffhangers In Anime/manga

The very first scene of the anime takes place a few weeks after the events of the Eclipse with Guts waiting for Godo to prepare the Dragonslayer. After the opening credits, the scene flashes two years later when Guts has a well-established reputation as the Black Swordsman. After defeating an apostle, the rest of the series reveals how Guts became the way he is in the present, starting with his first encounter with soon-to-be Big Bad Griffith. In the last episode, during the climax of the Eclipse, we see Guts screaming in rage and agony at the sight of the demon lord Femto raping Casca just as the credits role in. Although the very last scene reverts back to the very first scene, it is still left unclear as to how Guts managed to make it back from the hell dimension alive or whether Casca survived her ordeal and the viewers are still Left Hanging on this detail as Guts walks into the distance as the Black Swordsman, which is where the anime ends.
