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'm not sure specifically as there could be various themes in an 'Amagi English Light Novel'. It might be about adventure, fantasy, or relationships, just like many other light novels.
Well, in the 'amagi brilliant park novel', we can expect it to be full of interesting scenarios. It may focus on the charm of the park itself, with detailed descriptions of its architecture, scenery, and the different areas within it. There could be a group of main characters who have to deal with different challenges like low attendance, or some strange occurrences that are specific to the park. The novel might also explore the backstories of the characters, how they came to be associated with the park, and their personal goals and dreams that are intertwined with the fate of Amagi Brilliant Park.
