There could be more serious consequences too. Maybe she is even punished by some authority figure in the fanfiction. For example, she could be banned from certain places or activities, all because she was wrongly framed for hurting Lisanna. This would not only affect her socially but also limit her opportunities within the story's setting.
Lucy could face isolation. People in the fanfiction world might avoid her, and she could be left all alone. This could also lead to her losing confidence in herself as she is constantly being blamed for something she didn't do.
In the fanfiction world, it might be part of a bigger plot against Lucy. There could be a character who is jealous of Lucy's relationship with other characters. So, they decide to frame her for hurting Lisanna as a way to get her in trouble and drive a wedge between her and her friends.
Well, first of all, Lucy can try to have an open and honest conversation with Lisanna. By expressing her feelings and asking Lisanna why she is acting this way, she might be able to resolve the conflict. If that doesn't work, she can choose to rise above it. She can pour her energy into her magic training, become stronger, and show that she is not going to be brought down by Lisanna's actions. She can also look for new friendships outside of the group that may give her more positive energy and support. Another option is for Lucy to take a break from the situation. She can go on a solo adventure, clear her head, and come back with a new perspective on how to deal with Lisanna.
The plot could involve jealousy. Lucy might become jealous of Lisanna as she takes over her position in the guild. This could drive Lucy to train harder and become more independent. Maybe she'll find a new group of friends or allies who see her value outside of the guild.
In a fanfiction of Lucy being replaced by Lisanna, it might explore the emotional turmoil of Lucy. She could be heartbroken seeing how easily she was seemingly replaced. Meanwhile, Lisanna might not be fully aware of the situation or might be caught up in the sudden popularity. This could create a rift not only between Lucy and Lisanna but also within the guild as a whole. Some members might side with Lucy, feeling that she was unjustly pushed aside, while others might be excited about Lisanna's presence and not understand Lucy's pain.
Lisanna might face a lot of backlash from the guild. Her friends could be disappointed in her and might not trust her as much. She could lose her standing in the guild and have to work hard to regain people's respect.
One common theme could be jealousy. Maybe Lisanna is jealous of Lucy's relationship with Natsu and tries to come between them in the fanfiction. Another theme might be misunderstanding. Lisanna could misunderstand Lucy's intentions towards Natsu and act in a way that hurts Lucy. It could also be about competition for Natsu's affection, with Lisanna seeing Lucy as a rival and using underhanded tactics to make Lucy look bad in Natsu's eyes.
One popular plotline could be a love triangle between Natsu, Lucy, and Lisanna. For example, Natsu might be unknowingly caught between his long - standing friendship with Lisanna and his growing feelings for Lucy. Another plotline could involve the three of them on a dangerous adventure together, where they have to rely on each other's unique magical abilities to survive. Maybe they encounter a powerful dark wizard and have to work as a team to defeat him.
Perhaps Natsu is under the influence of a powerful and dark magic that makes him lose control of himself and accidentally hurt Lucy. It could also be that Natsu is trying to protect Lucy from something but his actions end up causing her harm instead. Like if he tries to keep her away from a dangerous situation by pushing her too hard and she gets injured.
One plot idea could be that Lucy and Lisanna team up for a special S - class mission. They face a powerful dark wizard who has the ability to control time. Along the way, they discover new magic spells and also learn more about each other's pasts. This would create a lot of action and character development.
One possible motive could be revenge. Another character might have a grudge against Lucy for something she did in the fictional world, like betraying a group or stealing something precious.
