One idea is that Yuma and Dark Mist accidentally swap bodies. This comical yet interesting situation could lead to a lot of chaos. Yuma has to deal with Dark Mist's powers and reputation while Dark Mist has to navigate Yuma's normal life. They both learn valuable lessons about each other and themselves as they try to find a way to swap back.
A plot could be where Dark Mist has a premonition about a future danger to Yuma. He tries to warn Yuma, but Yuma is initially skeptical. As events unfold, Yuma realizes that Dark Mist was right all along and they must team up to prevent the disaster. This could involve battles against new and powerful foes.
One possible fanfiction could be about Yuma and Dark Mist forming an unexpected alliance. Maybe Dark Mist has some hidden motives that initially seem malicious but as the story progresses, it turns out he's actually trying to protect Yuma from a greater evil in the Zexal world.
One idea could be exploring the backstories of the minor characters more in - depth. For example, what led them to become duelists in the first place. Another could be a time - travel plot where a character goes back to a crucial moment in the Zexal universe's history and changes something, leading to a whole new set of events and challenges. A third idea is to create a fanfiction where the main characters have to face a new, unknown type of duel that tests their skills and relationships in ways they haven't experienced before.
Maybe the reason for Yuma's kidnapping is not what it seems at first. Instead of being for his dueling abilities, it's because he has a hidden power that he's not even aware of. This power could be the key to saving or destroying the world of Zexal, and the kidnappers want to control it.
First, focus on their unique relationship. Astral is an otherworldly being and Yuma is a passionate duelist. Show how they learn from each other. For example, Yuma can teach Astral about human emotions, while Astral can teach Yuma advanced dueling strategies. Second, create exciting duels. Describe the cards in detail, the strategies used, and the tense moments during the duel. Third, introduce new elements like a mysterious new card set or a hidden dueling technique.
A simple plot could be that Yuma and Tori are exploring an ancient temple together. As they are about to be attacked by some sort of trap, Yuma quickly kisses Tori, believing it might be his last chance. This kiss then gives them a sudden burst of energy or a new power that allows them to escape the danger.
They could start as childhood friends who slowly fall in love. For instance, as they grow up in Heartland City, they share many experiences like going to school together and learning about dueling. One day, Yuma might get into a really tough duel and is on the verge of losing. Tori's unwavering belief in him gives him the strength to turn the duel around. This moment could be the spark that makes them realize their love for each other.
One good fanfiction could be 'The Encounter with Dark Mist in Yu - Gi - Oh Zexal'. It might explore a new duel where the protagonist has an unexpected encounter with Dark Mist and has to use unique strategies. Another could be 'Dark Mist's Origins in Zexal' which delves into the backstory of Dark Mist within the Zexal universe.
Well, in some fanfictions, their kiss might be a more impulsive act. For example, Yuma could be trying to prove a point to someone else, like a rival who doubts his feelings for Tori. So, he just goes for it and kisses her right there, which then leads to a whole new set of emotions and relationship developments for them both.
One possible fanfiction could involve Yuma being kidnapped by an unknown group who are after his powerful Xyz Monsters. They might hold him captive in an abandoned warehouse and try to force him to give up his deck. But Yuma, being the brave duelist he is, uses his wits and the bond with his Astral to find a way to escape and turn the tables on his captors.
First, you need to research about Yu - Gi - Oh Zexal and the character of Dark Mist. Know their traits, abilities, and the world they exist in. Then, come up with an interesting plot. For example, you could have a story where a new character is possessed by Dark Mist and the heroes have to save them. Keep the dueling rules in mind if you include duels in your fanfiction.
