Well, start by having a clear beginning, middle, and end in mind. Build up tension and conflicts gradually and make sure there's a satisfying resolution.
Not necessarily. There might have been earlier shows that incorporated story arcs, but Babylon 5 is often recognized as one of the pioneers in this aspect.
The season has multiple arcs. One major one involves the ongoing battle against various supernatural threats and the search for a way to prevent the apocalypse. Another arc focuses on the characters' personal growth and relationships.
One main arc is Geralt's search for Ciri. Ciri is a key figure with special abilities, and Geralt is determined to find her. Another arc involves the political unrest in the different kingdoms. Geralt gets caught up in the power struggles between rulers and different factions. And then there's the arc related to the Witchers themselves, their origin, and their role in the world.
To turn arcs into an anime story, think about the setting. A great setting can enhance the arcs. If the arc is set in a magical world, you can describe the unique landscapes, the strange creatures, and the magic system in detail. Also, consider the pacing. Don't rush through the arcs. Let the story unfold gradually, with moments of tension and relaxation to keep the viewers engaged.
Character development is key. Characters should grow and change throughout the arcs. For example, a shy character might become more confident. Another important element is the plot twists. They keep the story interesting. Like in an arc where a character thought they were fighting for a good cause, but then discovers it was all a lie.
