Well, he might be completely bewildered by all the modern technology. For example, seeing cars moving at high speeds on the roads could startle him. He could also have trouble adjusting to the social norms. Maybe he would accidentally draw too much attention to himself because of his unique appearance and old - fashioned ways of speaking.
If Sesshomaru enters Kagome's time in fanfiction, one possibility is that he becomes a sort of protector in this new world. He has his own sense of honor and duty. So, when he sees the chaos or danger that exists in Kagome's time, like crime in the cities, he might feel compelled to step in. At the same time, his presence could cause a stir in the scientific community as people try to figure out who he is and where he came from.
In fanfiction, if Sesshomaru goes to Kagome's time, he may encounter many things that challenge his beliefs. He is used to a world where power is often shown through physical strength and magic. But in Kagome's time, knowledge and intelligence are highly valued. He could either reject this new concept or start to adapt and learn from it. He might also meet some interesting people who would change his view of humans even more.
In fanfiction, if Sesshomaru were in Kagome's time, he might start to understand human society better. He could end up using modern things to his advantage. For example, he might use modern medicine to heal himself or his allies. And his relationship with Kagome could change. Instead of just seeing her as a nuisance in his own time, he could see her as a guide in this strange new world.
If Kagome meets Sesshomaru in modern time in fanfiction, it could start with Kagome being in a busy city street and suddenly sensing a strange and powerful presence. She turns around and there is Sesshomaru, looking out of place in his traditional attire. At first, Sesshomaru might be tempted to attack Kagome, thinking she is some sort of nuisance in this new world he has found himself in. But Kagome, being the kind - hearted person she is, tries to defuse the situation. She might offer to help him find a way back to his own time or at least get used to the modern world. This could lead to a series of comical situations, like Sesshomaru trying to fit into a small elevator or being startled by the sound of a cell phone ringing. As time passes, they could form an unlikely friendship, with Kagome learning more about Sesshomaru's past and him starting to respect her more.
Maybe it's part of a miscommunication plot. The author wants to show how misunderstandings can lead to harmful actions. Sesshomaru, being a complex character, could misinterpret Kagome's actions or intentions and end up hurting her accidentally. This would then lead to a journey of reconciliation and growth in the fanfiction.
It could become more complex. In her time, Kagome may be more in her element, which could make Sesshomaru see her in a new light. He might start to respect her more for her knowledge of this strange new world.
A possible plotline could be that Sesshomaru has to prove himself worthy to Kagome's family and friends. Since he has a reputation as a somewhat cold and aloof demon, this won't be easy. When Kagome gets pregnant, it adds more pressure. He has to show that he can be a reliable partner and father. Meanwhile, Kagome is trying to figure out how to combine her modern - world knowledge with the ways of the feudal era when it comes to raising a child.
Well, Kagome could end up helping younger Sesshomaru when he is injured. This would be a big shift in their relationship as Sesshomaru is not one to usually accept help from a human. But since he is younger, he might be more vulnerable and thus more likely to accept her aid.
He'd probably adapt slowly. First, he'd be confused by the new environment. But his natural intelligence would help. He might start by observing how humans interact with their strange devices. For example, seeing someone use a phone could be both fascinating and puzzling to him.
I really like 'Through Time's Veil'. In this fanfiction, Kagome's time - travel mishap lands her in a time when Sesshomaru is on a crucial quest. Their paths cross, and it's fascinating to see how they interact. Sesshomaru is initially suspicious of her but as the story progresses, they form an unlikely alliance. It's well - written with vivid descriptions of the Inuyasha world in different time periods.
Well, she could try to find a way to return him to his normal form. Maybe she'll search for some ancient magic or consult with a powerful sorcerer in the feudal era.
Another scenario could be that Sesshomaru gradually realizes that kidnapping Kagome to mate was a wrong move. As he spends time with her, he sees her kindness and intelligence, and he starts to develop a different kind of respect for her, rather than just seeing her as a potential mate. So he might let her go in the end.
