One possible plot idea could be Gajeel's family dealing with a new threat in the Fairy Tail world. Maybe they have to protect a powerful magical artifact that is being targeted by an evil guild. Another idea is exploring the family dynamics within Gajeel's family, like how they support each other during tough times or how they celebrate special occasions together.
A plot could involve Gajeel's family members each having their own personal growth journey. For instance, one of his family members discovers a new magical ability and has to learn to control it. This could lead to them facing various challenges and making new friends or enemies along the way. It could also be about how Gajeel's family heritage plays a role in their present - perhaps there are ancient family secrets that start to surface.
Lily could be a main character. He's Gajeel's loyal Exceed companion and has his own set of skills and a unique personality. Another could be Gajeel's family members like his parents if they are introduced in the fanfiction. They would bring in new perspectives and storylines related to Gajeel's past and family history.
A plot idea could be that their family goes on a journey to find a long - lost magical tome that Levy has always dreamed of reading. Along the way, they face various challenges like bandits and magical traps. Gajeel uses his combat skills to fend off threats, and Levy uses her knowledge to solve the puzzles.
In a Gajeel and Levy family fanfiction, it could be about how they handle family traditions. Levy might be from a family with a strong tradition of book - keeping magic knowledge. She could be trying to pass this on to their children, while Gajeel, with his more rough - around - the - edges background, has to adjust to these new family values.
One idea could be that the new generation has to face a powerful dark guild that is threatening the academy. They might discover new magic types along the way. For example, a character could find a lost ancient magic within the academy's hidden chambers.
Perhaps a fanfiction where Gajeel is cursed with a blue mark that slowly drains his energy. Levy, being the studious mage she is, devotes all her time to finding a cure. Along the way, they have to face many enemies who are after Gajeel's power. Their love and friendship are put to the test as they struggle to break the curse.
One idea could be that the children of the original Fairy Tail members have to form teams in high school to compete in magical battles, just like their parents did in the guild. This would create a lot of interesting rivalries and friendships.
Well, here's another plot. Levy starts training with a very skilled mage who is known for his gentle teaching methods. Gajeel is jealous because he feels like he should be the one teaching Levy. So, he challenges the other mage to a friendly duel. Levy is angry at Gajeel at first for being so possessive, but later she understands that it's his way of showing his care for her. During the duel, Gajeel realizes that the other mage is not a threat to his relationship with Levy and they all become friends in the end.
A possible plot could be that Gajeel and Levy go on a journey to find a special place to raise their child. Along the way, they encounter old enemies who now see the pregnant Levy as an easy target. But they fight together, with Gajeel being extra protective. Also, they could have different ideas about parenting. Levy might want a more studious and peaceful upbringing for the baby, while Gajeel wants to train the baby to be tough from a young age. They then have to find a middle ground.
One idea could be that Levy discovers she's pregnant during a big guild mission. This could add a whole new layer of tension as Gajeel becomes overly protective. Maybe they have to face an enemy who specifically targets Levy because of her pregnancy. Another plot could involve Levy struggling with the changes in her body and magic while pregnant, and Gajeel having to learn how to support her in ways he never thought possible.
Perhaps there's a fanfiction where Levy is praised for her intelligence in front of the whole guild by an elder mage. Gajeel, feeling a bit inferior in that aspect, gets jealous. He starts to study more magic theory secretly to impress Levy. Along the way, there are cute moments where he tries to ask Levy for help without admitting his real motive, and it all builds up to a heartwarming moment between them.
