It would probably bring a new kind of warmth to the guild. Everyone in Fairy Tail loves family - like relationships, and Lucy and Mira being sisters would be a really cute addition. The other guild members would likely be very protective of their new 'sisterly' bond.", "Answer2":: "This new relationship could also change how missions are assigned. Maybe the guild master would send them on more sister - duo missions. And when they are on these missions, they could use their combined skills to gain more fame for the guild. For example, Mira could use her transformation magic to distract enemies while Lucy summons her spirits for the attack. This would make the guild seem even more united and strong.
Also, in terms of the social aspect within the guild, there would be more parties and celebrations centered around their sisterhood. It could inspire other guild members to form closer bonds as well. For instance, Natsu and Gray might be inspired to be more like brothers instead of just rivals. And the younger members of the guild would look up to Lucy and Mira's sisterly relationship as something to aspire to.
Well, it could be a story full of sisterly love and adventures. Maybe Lucy and Mira would go on quests together, with Lucy's celestial spirit magic and Mira's take - over magic complementing each other. They could face powerful enemies and protect their guild mates as sisters.
She would fit in very well. The Fairy Tail guild is all about family and acceptance. Given her parents are Lucy and Natsu, she'd be welcomed with open arms. She could learn from the older members like Makarov and Mirajane, and bond with the younger ones like Romeo. Her magic skills would also contribute to the guild's strength during battles or when helping the town.
The guild as a whole would likely mobilize. Erza would start formulating a strategic plan. She'd consider the strengths and weaknesses of Acnologia and figure out the best way to approach the situation. Gray would also be ready to fight, using his ice - make magic to support the rescue mission. They would all be united in their determination to get Lucy back safely.
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.
The guild would likely be ecstatic. Gray would probably make some snarky comment about Natsu finally growing up, but deep down he'd be happy for his friend. Erza would be all for it and might start planning the wedding immediately, giving orders to everyone in the guild to help out.
It could lead to a change in the guild's dynamics. Naruto has his own unique combat style and abilities. His departure might make the guild realize the need to diversify their fighting strategies. For example, they might start to look for members with skills similar to Naruto's ninja techniques.
Her relationship with Natsu would likely change. Natsu might be initially distrustful of Lucy if he senses her connection to End, since End is often seen as an enemy. But then as he realizes that Lucy is still the same person deep down, their bond could become even stronger as he helps her control this new aspect of herself.
There could be a void in the guild's social dynamic. Lucy is often involved in the guild's daily activities and socializing. Without her around, the guild might seem a bit quieter and less lively. The other members would have to adjust to her absence, and this could lead to some changes in the relationships within the guild.
Drunk Lucy could also be very argumentative. She might start debates with the more serious guild members like Erza about the silliest things, like whether or not it's proper to eat cake with a fork or hands. This would lead to some comical exchanges as the other members watch in amusement.
Their relationship could develop through shared secrets. For example, they might discover something about the guild's past that they decide to keep between themselves. This would create a special bond.
