Well, perhaps a fanfiction where Mavis and Larcade get transported to a different dimension. In this dimension, they lose their magic at first and have to learn to survive and work together without it. This would test their characters and also allow for a lot of character development. Or maybe they find a young mage in this dimension who is in great danger, and they have to protect this mage while also finding a way back home. Another option is that Larcade discovers a secret about Mavis that could change the course of the Fairy Tail guild's future, and they have to deal with this secret together.
One idea could be that Mavis and Larcade discover a long - lost magic that has the power to either save or destroy the Fairy Tail guild. They have to decide what to do with it together. Another could be that Larcade is somehow related to Mavis's past in a way she never expected, like they share a common ancestor who was a great mage. A third idea is that they team up to fight a new, powerful dark guild that threatens not just Fairy Tail but the whole magical world.
A possible plot for a Mavis and Larcade fanfiction could be centered around a magical artifact. Let's say there's an ancient artifact that is said to grant unlimited power.

So they decide to join forces to either find and protect it or destroy it if necessary. Along the way, they face many challenges and learn more about each other's strengths and weaknesses. This could also lead to a deeper friendship or something more between them as they go through these trials together.
One idea could be that the OC has a special power that Mavis senses and they form a connection through it.

For example, Naruto could use his shadow clone jutsu to confuse enemies while Mavis uses her Fairy Magic to attack from another angle.
