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 is still alive in the manga. The story keeps evolving with him at the center of the action. There have been many difficult situations, but he manages to overcome them without dying.
I have no idea who the author of the 'first to fight novel' is. There are so many novels out there, and without more information, it's impossible to determine the author.
Well, without more context, it's difficult to say exactly. If it's a military - themed 'first to fight novel', it could focus on the experiences, courage, and challenges of the front - line soldiers who are the first to enter combat. It may detail their training, their relationships with comrades, and how they deal with the horrors of war. It could also explore themes like heroism and sacrifice.
