Their friends would have a wide range of reactions. Ishida would be the one to make sure everything was in order, like the invitations and the seating arrangements. He would be very meticulous. Renji would be all excited and would probably want to show off some new moves during the wedding reception as a form of celebration. Orihime's friends from school would be squealing with excitement, constantly talking about the wedding and how beautiful Orihime will look. And Ichigo's dad would be a bit of a wild card, maybe causing some chaos in the name of celebration but also being really proud of his son.
Their friends would be really excited. Chad would probably be happy and offer to help with any heavy lifting or physical tasks around the house for when the baby arrives. Uryu might be a bit more reserved but still show his support in his own way, like making some special baby clothes. Rukia would be thrilled and would be constantly visiting, giving Orihime advice on motherhood.
Chad would be a very protective and gentle presence. He would be like an uncle to the baby, always ready to pick the baby up and play with it. His calm and strong nature would make the baby feel safe.
Chad would be excited and happy for them. He's always been a loyal friend to Ichigo, and he would see Yoruichi as a great match for him. He might even offer to help with the wedding preparations.
Most of their friends would be very excited. For instance, Bakura could give them a special gift, perhaps something with a bit of mystery or history behind it. Duke could offer to use his game shop as a place for the pre - wedding party. And all of their friends would come together to plan a really memorable bachelor and bachelorette parties for Yugi and Tea respectively. There would be lots of laughter, reminiscing about old times, and looking forward to the new chapter in Yugi and Tea's lives.
Their friends would likely be overjoyed. Happy for the couple and excited to be part of the wedding. For example, Natsu might be a bit rowdy but full of genuine happiness for Rogue, while Erza would be more composed and offer practical help with the wedding preparations. Levy would probably be helping Lucy pick out the perfect dress and gushing about how romantic it all is.
Maybe the wedding is a ruse to draw out an enemy. Ichigo and Orihime pretend to be getting married, but in reality, they are setting a trap. However, as they go through the motions of the wedding preparations, they start to realize how much they actually do want to get married for real. So, in the end, after defeating the enemy, they decide to have a real wedding. It could also be that Orihime's family has some ancient traditions related to marriage that Ichigo has to go through, which could lead to some really funny and heartwarming moments.
One idea could be a post - war story where Ichigo and Orihime finally tie the knot. They could have a traditional Japanese wedding with all their friends and family from the Soul Society and the human world in attendance. Another plot could be a story where they face some last - minute challenges before the wedding, like an old enemy trying to disrupt their happiness. Maybe Orihime has doubts about whether she's truly worthy of Ichigo, and they have to work through those insecurities together.
Sasuke would probably have a complex reaction. He might feel a bit of envy deep down but also be happy for them on the surface. Kakashi would be very supportive and would likely give them some sage advice about marriage, like how to always communicate and trust each other. Shikamaru would be like 'What a drag, but congratulations anyway' in his typical laid - back style.
Ichigo's family on the other hand, would also be surprised. His father might be a bit more open - minded though, given his own strange abilities and knowledge of the spirit world. His sisters would likely be excited about having Byakuya as a brother - in - law, especially if they see how much Ichigo cares about him. Overall, Ichigo's family would probably welcome Byakuya once they get to know him better.
Ichigo's family might be a bit surprised at first. His father, Isshin, would probably be happy in the end though, seeing his son find love. His sisters might be excited to have Rangiku as part of the family and look forward to all the fun they could have together. As for Rangiku's side, if she has any family in the Soul Society, they might be a bit more hesitant. They might worry about how a relationship with a human like Ichigo could work out in the long run, but eventually come around when they see how much they love each other.
