Sakura's reaction would be complex. She has deep - seated feelings for Sasuke, so it would be a hard pill to swallow. However, as a medical ninja, she would also feel a sense of responsibility towards Sasuke's pregnancy. She might offer to be Sasuke's doctor throughout the pregnancy. Naruto's friends like Rock Lee would be over the moon for him. Lee would see it as Naruto achieving another great milestone in his life. He would constantly cheer them on and might even start training extra hard in case he needs to protect the new family. As for the other Konoha ninjas, they would initially be skeptical but gradually accept the situation as they see Naruto and Sasuke's determination to build a family together.
Shikamaru would likely be his usual laid - back self on the outside, but secretly he'd be thinking about all the implications this has for the village and their team dynamics. He might offer some practical advice like how to manage their time and resources better now that they're going to be parents. Choji would be excited and would probably start thinking about all the delicious food he could bring for Ino during her pregnancy to make sure she and the baby are well - nourished.
The friends from Gaara's village, like Temari and Kankuro, would be very protective. Temari would likely give Naruto the 'big sister' talk, warning him to take good care of Gaara. As for Naruto's friends, they would support him wholeheartedly. Choji might bring over some of his favorite snacks for Gaara, thinking it would be good for the baby. And Hinata would be quietly supportive, maybe knitting some baby clothes in her spare time.
Sakura might be initially shocked and a bit jealous, but as a friend, she would probably come around and support them. She has grown as a character and would understand the importance of their relationship.
Sakura would probably be shocked at first, but then she'd be supportive. She might offer her medical skills to help with Tenten's pregnancy. Shikamaru would likely think it's a troublesome situation but would also offer his strategic advice on how to handle things. Kakashi would be his usual calm self and give them some wise words about responsibility and family.
Naruto's friends like Sakura and Kakashi might be initially shocked. Sakura, as a medical ninja, would offer her medical expertise to help Cana during the pregnancy. Kakashi would probably be more reserved but offer his wisdom and protection. On Cana's side, her friends from her own world might be skeptical of Naruto at first, but as they see how much he cares for Cana, they start to accept him.
Sasuke would probably be very confused at first. He has spent so much time hating Itachi for what he did to the Uchiha clan. Seeing Naruto befriend Itachi would make him question his own long - held beliefs. He might initially be angry with Naruto for seemingly siding with his enemy.
Sasuke would be furious. He's always been protective of Naruto in his own way. He would immediately start looking for her, using all his skills and resources. He might even go on a rampage if he thought Naruto was in serious danger.
Naruto's friends from Konoha would likely be very supportive. Kakashi might offer some wise words about the responsibilities of parenthood. Sakura would probably be there to help with any medical concerns Mirajane might have during the pregnancy. As for Mirajane's friends from Fairy Tail, they would be excited. Erza would be making sure Mirajane is well - protected and would probably train Naruto a bit to make sure he can defend his family. Gray might make some jokes to lighten the mood but also be ready to help out.
Sakura would probably be a bit shocked at first but then be very supportive. She has always cared about both Naruto and Sasuke, so she would likely be there to help with the baby's medical needs if any. Kakashi would be the cool uncle type. He'd offer his wisdom and maybe some training tips for when the baby grows up.
His friends would be really happy. Shikamaru would probably be like 'Well, it was bound to happen eventually, Naruto.' and offer some practical advice. Choji might bring over some delicious food for Hinata to help with her pregnancy cravings. Kiba would probably joke around with Naruto about how his life is really changing now.
