Naruto's friends like Shikamaru and Kiba would likely be full of jokes. They would tease Naruko in a friendly way, but also be concerned. Shikamaru would probably be the first to think that there's more to it than meets the eye and start coming up with theories. Kiba, on the other hand, might be a bit more straightforward and just ask Naruko directly what's up, while his dog Akamaru would be sniffing around, adding to the chaos.
The Weasley family would have a range of reactions. Mrs. Weasley would probably be very maternal towards Harry, seeing Lily in his face. Ginny might be a bit shy around Harry at first, seeing him in a new light. Fred and George would likely use it for some good - natured teasing, like creating potions that make Harry's hair grow really long to enhance the resemblance. And Snape, well, seeing Harry look like Lily would be a constant reminder of his unrequited love. He might be even more conflicted in his feelings towards Harry, part of him hating Harry for being James' son but also being drawn to him because of his likeness to Lily.
Well, it could be a story about some kind of magic gone wrong. Maybe she was experimenting with a new jutsu and it had an unexpected side effect that made her appear pregnant. Or perhaps it's a prank played on her by one of her friends using a transformation jutsu that backfired in a way that she ended up looking pregnant.
Master Fu might be a bit more cautious. He would see the potential risks not only to Ladybug but also to the Miraculous. He might try to find a way to transfer the Miraculous to someone else temporarily during her pregnancy to ensure its safety. But he would also understand Ladybug's determination and try to support her as best he can while still being concerned about the balance of the Miraculous world.
Miroku would probably be very supportive. He would offer his wisdom and advice based on his knowledge of the spiritual and worldly matters. He might also joke around a bit with Inuyasha about the upcoming fatherhood, like giving him some 'words of caution' in a light - hearted way. Sango would be very helpful to Kagome. She could share her own experiences of taking care of children, even if it's mainly about her younger brother. She would be there to comfort Kagome during the difficult times of pregnancy, like when she's feeling sick or moody.
The other characters' reactions could vary widely. His close friends in the fanfic might be in a state of panic, crying and not knowing what to do. Enemies, on the other hand, might see it as an opportunity to take advantage, or they could also be secretly worried depending on the complexity of their relationships. And there could be those characters who are just bystanders, shocked at first and then trying to figure out what happened.
Simba, if he's still in a leadership role, would likely be cautious yet supportive. He'd want to make sure that Vitani's pregnancy doesn't cause any unrest in the pride. He might offer his wisdom on how to raise a strong and noble cub. And the younger lions in the pride could look up to Vitani with newfound respect, seeing her as a symbol of new life and the future of the pride.
Zabuza would probably be initially shocked. He might see it as a complication to their plans, but as time goes on, he could become protective. Naruto, being the kind - hearted person he is, would likely offer his support and friendship. He might not fully understand Haku's situation at first, but he would try to be there for her.
The younger lions might be excited. They could see the upcoming cubs as new playmates. They might start preparing little dens or areas for the cubs to play in once they are born, using things like leaves and small branches.
Naruko herself would probably be shocked at first, but then she would start trying to reason with Sasuke. She would ask him why he's doing this and try to make him see that whatever he's thinking is wrong. She's a strong - willed character and wouldn't just sit there passively.
Haku would likely be very protective. He has a special bond with Chihiro already, so when she turns into a spirit, he would probably try to guide her through the changes. He might teach her how to use her new spiritual powers. No - Face, on the other hand, could be either curious or envious. Since No - Face is always in search of something, seeing Chihiro transform into a spirit might make him wonder if she has found a new kind of fulfillment. The bathhouse workers might be initially shocked and a bit afraid. They are used to dealing with normal spirits, but Chihiro's transformation is something unexpected and they might worry about how it will affect the balance in the bathhouse.
