One idea could be a story where the female protagonist and Morgana go on a solo adventure in the Metaverse. They discover a new Palace that no one else has found yet and have to figure out how to take it down together. Another plot could involve Morgana getting lost in the real world and the female character has to find him using her wits and knowledge of his habits. A third idea might be a story where Morgana and the female character share their dreams and aspirations over a late - night conversation in Leblanc.
To write a good relationship, show mutual respect. For example, the female protagonist could always listen to Morgana's advice and Morgana could respect her decisions. They could also have inside jokes, like a special code word for when they're in a tough situation in the Metaverse.
In 'Persona 4 Visual Novel', the gay persona might represent the diversity of the game's character creation and the exploration of different sexual orientations within the game's fictional world. It could add more depth to the relationships and storylines.
Perhaps the fanfiction focuses on the cultural clash between the two groups. The Persona 4 characters are from a small town, while the Persona 5 crew is from the big city. Their different ways of handling things and their unique Personas could lead to some interesting interactions. For example, Yu and Joker might have different leadership styles that they have to reconcile in order to succeed against the shadows.
She could be shocked at first. After all, Merlin has been hiding his magic for so long. Maybe she feels a sense of betrayal initially, but then she might see an opportunity to have an ally in the world of magic.
He wasn't sure. The information I know about the source and background of the Ao Ao awaiting arrest comic is very limited. It could be adapted from a novel or an original. If you can provide more information about the manga, I will try my best to answer your questions.
One possibility is that there would be a great deal of tension. Old Merlin has seen so much and has his own wisdom, while Morgana has her own powers and motives. Maybe Merlin would try to persuade Morgana to abandon her dark path. He could use his experience and the bond they once had to appeal to her better nature.
Their relationship could develop in a complex way. If Morgana ties up Merlin out of anger or suspicion initially, but then realizes she was wrong, it could lead to her feeling guilty. This might make her more open to Merlin's friendship in the future, and they could gradually build trust.
A great plot could be that a new threat emerges that has the power to erase the memories of people in both Persona 4 and Persona 5's worlds. The characters from both games must work together to find the source of this threat. The Phantom Thieves could use their infiltration skills, while the Investigation Team could use their detective - like skills to gather clues. As they progress, they discover that the root of the problem lies in an ancient evil that was once sealed away but has now been awakened due to some modern - day events.
