I think most of the guild would be overjoyed. Mirajane would be all smiles and start planning a baby shower right away. Elfman would probably give Gajeel some man - to - man advice on fatherhood. Cana might bet on whether the baby will be a boy or a girl. And Wendy would be eager to use her healing magic to make sure Levy has a healthy pregnancy.
The other members of Fairy Tail would likely be very excited. Natsu might be a bit clueless at first but would soon be happy for them. Lucy would probably be super excited and offer to help Levy with anything she needs. Erza would be more reserved in her excitement but would offer her protection. Gray would probably make some teasing remarks to Gajeel about becoming a father.
Well, their friends' reactions would be quite diverse. Some like Happy would be constantly bringing small gifts for the baby. Makarov, as the guild master, would be proud and offer his wisdom and support. Jet and Droy, being Levy's old friends, would be a bit overprotective at first. But overall, the guild would come together to support Levy and Gajeel during this new chapter of their lives, with everyone adding their own unique touch to the celebration and support.
Their friends would probably be very excited. The other Fairy Tail members might throw a big celebration for them. Some of the female members, like Lucy, would be super helpful to Levy, giving her advice on pregnancy and helping her with things like shopping for baby clothes.
Their marriage could also lead to more diplomatic relations within the guild. Levy is friendly with most members, and Gajeel has his own group of comrades. Their union could bridge any gaps between different cliques in the guild. For instance, if there were disputes between the more bookish members and the combat - focused ones, Gajeel and Levy could step in and mediate, using their combined influence.
Their relationship would likely become more protective. Gajeel would be constantly on guard to keep Levy and the unborn baby safe. He'd be more gentle and caring towards her.
He'd probably be stunned at first. Just stand there with his mouth open a bit. Then, he'd break into a big grin and hug Levy tightly.
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.
Their friends in Fairy Tail would likely be very excited. Erza, for example, would probably be super supportive and offer practical advice on things like baby - proofing a home. Natsu might be a bit clueless at first but would be really happy for them. Lucy would be thrilled and might start knitting baby clothes. Happy would be flying around them, chirping happily. Overall, their friends would form a great support system for Gray and Juvia during this time.
Their friends would likely be very excited. Lucy would probably be overjoyed and offer to help with things like baby clothes shopping. Gray might act a bit gruff on the outside but secretly be happy for them. Erza would be very protective, making sure that Lisanna has everything she needs and that the guild is a safe environment for the baby. Happy, Natsu's Exceed friend, would be constantly around, making cute comments about the baby and offering his own unique brand of support.
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.
I recommend 'Gajeel and Levy: A New Chapter'. This fanfiction takes place after a big event in the Fairy Tail world. It shows how they start a new phase in their relationship, like moving in together or starting a joint project within the guild. 'The Levy - Gajeel Love Story' is also quite good. It's a more traditional love story - type of fanfiction that details their courtship and how they deal with the opinions of their friends in the guild. And 'Gajeel's Protection of Levy' is a fanfiction that emphasizes Gajeel's protective side towards Levy. It has some exciting plot twists where Gajeel has to save Levy from various threats.
