Since lemon fanfics are inappropriate, we should focus on their general characteristics from the official story. Asta is highly determined and energetic, always striving hard despite his lack of magic initially. Yuno, on the other hand, is more calm and has a natural talent for magic. They both have a strong bond as rivals and friends.
Noelle could be a great addition. Her water magic is quite powerful and she has a complex relationship with both Asta and Yuno. She could be a source of both support and conflict in the fanfic. Another good character is Luck. His lightning magic and his rather unpredictable nature can add a lot of action and excitement to the story.
Asta would likely bring a new level of determination to the Crimson Lions. His never - give - up attitude could inspire the team members during tough battles.
Asta in an elf fanfic might be the protagonist. He could be on a quest, perhaps to save the elves from some great danger or to discover a hidden secret within the elven realm. He might form alliances with different elven clans and face many challenges along the way, like fighting against dark magic or evil creatures that threaten the elven way of life.
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.
I'm not sure specifically what 'asta has magic fanfic' is about as there could be many interpretations.

Maybe it's related to a particular anime or book series where fans have written their own stories about Asta's magical abilities.
A common theme is Asta's growth. In these fanfics, he often starts as a novice in the game world and gradually becomes stronger. For example, he might learn new skills or unlock hidden abilities.
One appropriate theme could be Asta's training journey. It can detail how he overcomes difficulties in his training, like pushing his physical limits and mastering new magic techniques.
One common theme is the growth of their relationship. It often shows how their feelings develop over time, from being just comrades to something more romantic.
