Gray would be in shock at first. He has always had Juvia by his side, and her sudden death would be like a part of him being ripped away. He would likely start to question his own actions and decisions that led up to her death. In his grief, he might become reckless in his battles, not caring about his own safety as much. He would also carry a deep sense of guilt, thinking that he didn't value Juvia enough when she was alive. As time passes, he would become more withdrawn and the once - cold - hearted Gray would seem even colder, but it's really just his way of hiding the pain of losing Juvia.
Gray would be devastated. He might go into a state of deep depression, isolating himself from the rest of the Fairy Tail guild. He would blame himself for not being able to protect her, especially if her death was related to her love for him. Gray would probably be filled with anger as well, and he would vow to take revenge on whoever was responsible for her death.
Well, it could make Gray feel an extreme sense of guilt. He might blame himself for not being able to protect her. And this could lead to him becoming more withdrawn and brooding, perhaps even pushing away his friends as he grapples with the loss.
In some Fairy Tail fanfictions where Juvia dies, it could be a very emotional and impactful scenario. It might be due to a powerful enemy she couldn't defeat, sacrificing herself to save Gray or her friends. Her death could lead to Gray's character development, making him more determined to fight against the forces that took Juvia from him.
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.
In many fanfictions where Gray confesses to Juvia, it's often a very emotional moment. It might happen after a big battle where they realize how much they mean to each other. Gray could finally admit his feelings that he has been suppressing for a long time. Maybe he sees Juvia in danger and that makes him realize he can't hide his love anymore.
One possible reason could be self - sacrifice. Juvia might give up her life to protect Gray from a deadly attack. She loves Gray deeply, so sacrificing herself for him would be in character.
Juvia might become very sad and withdrawn. She could start to doubt herself and her worthiness of love. In some fanfictions, she might cry a lot and isolate herself from others in the guild, thinking that she has done something wrong to make Gray reject her.
Well, in some fanfictions, Gray's love for Juvia is shown through his jealousy. When other guys get too close to Juvia, Gray gets this possessive feeling that he doesn't quite understand at first. It's a sign that his feelings for her are deeper than he thought.
In fanfiction, Gray's love for Juvia can be portrayed in many ways. Sometimes it's a slow - burn kind of love. Gray, who is initially cold towards Juvia, gradually realizes her importance in his life as she is always there for him, through battles and difficult times.
One possible scenario could be Juvia sacrificing herself to save Gray. In the heat of a battle against a powerful enemy, Juvia might use her water magic to shield Gray from a fatal attack, but at the cost of her own life. Another could be that she succumbs to a dark magic that she was trying to fight off alone, not wanting to endanger her friends. Maybe she gets caught in a cross - fire between two extremely powerful magic users and her body is too weak to withstand the impact.
Another great author is 'RainbowMageFan'. This author likes to create unique and exciting plotlines. For example, they might write a story where Juvia and Gray get transported to a magical realm full of strange creatures and they have to find their way back while also dealing with their growing feelings for each other. Their writing style is very engaging.
