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.
A plot could involve Dark Ichigo and Orihime getting trapped in an alternate dimension. In this dimension, they have to rely on each other to survive. Dark Ichigo has his brute strength, but Orihime has her powers that could be useful in different ways. Their relationship would develop as they face various challenges together in this strange new world.
One idea could be exploring how Ichigo and Orihime deal with the challenges of raising a Quincy - Hollow hybrid child. Since Ichigo has both Hollow and Shinigami powers and Orihime has her own unique abilities, their child might inherit a complex set of powers.
Perhaps there's a world where vampires and Soul Reapers co - exist, and Ichigo and Orihime get caught in the middle of a power struggle between the two groups. Orihime's powers might be the key to peace, and Ichigo is determined to protect her.
One idea could be that Ichigo, Rukia, and Orihime discover a strange lemon - shaped spiritual artifact. They have to figure out its powers and how it relates to the Soul Society. Maybe it has the power to enhance their spiritual abilities, but also comes with a strange side - effect that changes their relationships in unexpected ways.
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.
One idea could be exploring how they adjust to the news. Maybe Ichigo becomes overly protective and Orihime has to calm him down. Another could be their friends' reactions. Chad might be really supportive while Uryu is a bit more reserved at first but then warms up.
There are indeed. One common theme in these fanfictions is the cultural differences they have to overcome in their married life. Ichigo is from a more human - centered world, while Orihime has strong ties to the Soul Society. Their marriage is a blend of these two worlds, and the fanfictions often show how they bridge the gap between their different backgrounds.
I'm not sure about a specific 'Ichigo and Orihime lemon fanfiction' title off - hand. But you can often find great ones on fanfiction websites. Just search for 'Ichigo Orihime relationship fanfiction' and look through the results. You might have to sift through a bit to find the ones that are well - written and suit your taste.
One interesting plot idea could be a story that focuses on their wedding preparations. It could show how Naruto, who is not used to all the formalities, struggles with choosing the right wedding kimono or learning the proper wedding etiquette. Hinata, on the other hand, is more in tune with the traditional aspects but is nervous about becoming the wife of the Hokage. Another idea could be a time - travel fanfic where they go back in time to their first meetings and relive those moments with the knowledge of their future together. It would be a chance for them to see how far they've come and how their relationship has developed over the years.
