One common theme is the growth of their relationship. Since in the original story their relationship has potential for development, fanfics often explore how they get closer over time. For example, through shared adventures or moments of mutual understanding.
Growth is also a theme. Noelle crying might be a turning point for her character. It could be the moment she decides to be more open about her feelings, both to Asta and to herself. This can lead to her personal growth in the fanfic.
Perhaps in the fanfic, there is a misunderstanding. Asta might accidentally say something that makes Noelle think he doesn't care about her. This could lead to Noelle crying, and Asta then has to figure out what he said wrong and make it up to her. It could be a story about miscommunication and making amends.
One possible plot could be that they are in a spooky dungeon during a mission. Noelle is scared of the dark and the unknown creatures lurking. Asta, being his brave self, tries to comfort her and protect her. As they face different challenges, their relationship deepens.
Romance is also a common theme. Since they are two main characters in the series, many fanfics explore the budding relationship between Asta and Noelle. This can range from a slow - burn romance where they gradually realize their feelings for each other, to more fast - paced stories where their love is more immediate. It adds an interesting dynamic to the stories.
Well, another place could be some dedicated anime fan communities. For example, Reddit has some subreddits related to the anime that Asta and Noelle are from. Sometimes fans share their fanfictions there or can point you in the right direction. Just make sure to follow the rules of the community.
In asta and noelle fanfiction, a common theme is power - related. Since they both have different powers in the original story, writers might explore how their powers interact or complement each other. There's also the theme of family acceptance. Noelle has her family issues, and Asta is from a different background, so stories might revolve around how they deal with family - related matters together. Also, the theme of friendship turning into love is quite popular. They start as comrades and then gradually develop deeper feelings for each other.
In the manga, Asta and Noelle's relationship progresses gradually. They face many challenges together, and eventually, their feelings for each other blossom into a romantic connection.
As of the latest manga chapters, Asta and Noelle haven't gotten together. Their relationship is still evolving and it's unclear if they will end up as a couple in the future.
