Shikamaru would be like, 'Well, that was expected. Took them long enough.' He'd be laid - back about it but still show his support in his own way, like helping with the wedding preparations in a very efficient but not overly enthusiastic manner.
Sakura might be a bit more reserved in her reaction. She and Ino have a complex relationship. While she'd be happy for Ino, there could also be a tinge of envy or worry. Maybe she's worried that Ino will be too focused on her new married life and their friendship will fade a bit.
Naruto would probably be super excited and offer all kinds of help. He might bring over some of Hinata's home - cooked meals for Ino. Sakura would be very practical, offering her medical expertise and making sure Ino is having regular check - ups. Shikamaru would be more laid - back but still offer some sage advice about the responsibilities of parenthood.
Harry might be initially skeptical. He has a history with Draco, so he'd be worried for Ginny. But over time, if he sees how happy Draco makes Ginny, he could come around. Hermione would probably be more open - minded. She'd look at Draco's character development and judge based on that. Ron, on the other hand, would be the most difficult. He'd be very protective of Ginny and would likely grumble a lot at first.
Ino would be very involved. Since she's Sakura's friend, she would be constantly checking on Sakura, giving her advice on pregnancy - related things like what to eat and what not to do. And she would also be helping with preparing things for the baby, like baby clothes and a nursery.
Choji would probably be super excited. He's their close friend and would likely offer to cook all kinds of delicious and healthy food for Ino during her pregnancy. Naruto might be a bit clumsy at first but would be very enthusiastic, offering to do any odd jobs they need. Sakura, being a medical ninja, would be very practical, giving Ino regular check - ups and advice on how to stay healthy. And Kakashi might give Shikamaru some father - to - be advice in his laid - back but wise way.
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 other Sailor Scouts would be really happy for Usagi. They know how much she loves and how she has always been there for them, so they would welcome Seiya into the group wholeheartedly. Mamoru might be a bit surprised at first, but he would soon come to terms with it and wish them well.
Iruka sensei would be very proud of Naruto. He has been like a father figure to Naruto, and seeing him get married to Sakura would make him feel like Naruto has truly grown up. As for the other villagers, most of them would be happy as Naruto is a hero. They would see Sakura as a great match for him, someone who can support him and also contribute to the village with her skills.
Friends from different wizarding groups could react in different ways. The Gryffindors would be celebrating loudly and proudly. The Hufflepuffs might be the ones making sure everyone feels welcome and included in the wedding festivities. Meanwhile, the Ravenclaws could be giving intellectual toasts about the significance of their union in the wizarding world's history.
Clark might be very happy for them. He would see it as a great union that could bring more good to the world. He might offer to be the best man or help in any way he can.
Guy would be extremely excited. He'd probably see it as a new opportunity for friendly rivalry. He might challenge Kakashi to be the best husband, like he challenges him in other aspects. Asuma would be more laid - back, giving Kakashi some advice on how to deal with Anko's temper. Kurenai would be happy for Anko, offering to help her with any wedding preparations and later, with domestic things. Naruto would be over - the - moon. He looks up to Kakashi, and seeing him get married would be like a fairytale for Naruto. He'd probably pester them to tell him all about their relationship.
