Zoro would be deeply affected. He has sworn to follow Luffy and his death would be a huge blow. He might feel like he failed in his duty to protect the captain. He would likely become more withdrawn at first, but then focus on getting stronger to avenge Luffy if there was someone to blame for his death.
Nami might be shocked at first. She'd probably look at Luffy with wide eyes, not believing what she just heard. After all, Luffy is not the most romantic or traditional suitor.
The crewmates would have a range of reactions. For one, they trust Luffy's ability to handle himself, but they'd also be eager to reunite with him. Luffy's impulsive nature often leads him into adventures, and this time it's in a whole new world. The more level - headed ones like Nami and Robin would be thinking of strategies to either bring him back or join him. The fighters like Zoro and Sanji would be prepared to defend Luffy against any threats in this new and unknown Naruto world. And the rest of the crew would contribute in their own unique ways, whether it's through humor like Brook or scientific exploration like Franky.
Some villagers might be shocked and horrified. Naruto has always been seen as a hero, and this act of killing the council would shatter that image for many. They would fear that Naruto has gone rogue and might pose a threat to them.
The villagers' reaction would be a mix of excitement and some concerns. On one hand, Naruto's popularity among the younger ninjas is huge. His friends like Sakura and Shikamaru would be his biggest supporters and help him in his new role. However, some of the more traditional clans might worry that Naruto's unorthodox ways could disrupt the long - established order in the village. But over time, as Naruto shows his ability to balance his unique style with the responsibilities of the Hokage, they'd come around.
They might be shocked. Luffy's Gear 5 is such a powerful and strange form. In the fanfiction, characters could be amazed at his new abilities, like his cartoon - like movements and seemingly limitless power.
Nami would probably be devastated. She has been with Luffy through so much, and his death would be a huge blow. She might become more withdrawn and serious, as Luffy was often the one to bring out her lighter side.
Nami would probably be shocked at first. She might worry about how this would affect Luffy's journey to become Pirate King. But then she would likely start thinking about practical things like how to take care of the baby on the ship. Sanji would be over the moon, seeing it as an opportunity to cook for a new little life. He might also be a bit jealous that it's Luffy and not him having a baby with Hancock.
Blackbeard's crew is also a diverse bunch. His more aggressive members like Burgess might be eager to start a fight with Luffy's crew. However, some of the more cunning members could be thinking of ways to use the situation to their advantage. They might try to manipulate Luffy or his crew into making mistakes. And if Blackbeard decides on a certain course of action, his crew would generally follow, but there could be some internal dissent depending on the situation.
