One common element is the contrast between the dark situation of abuse and the hope of rescue. Usually, Kagome is in a really bad situation, like being held captive or mistreated, and then there's a turning point where she is saved. Another element could be the presence of a protector figure. This might be a character from the original series or an original character created for the fanfiction.
There's also 'Draco's Salvation of Harry'. It delves deep into the reasons why Harry was being abused and how Draco, who has his own growth arc in the story, manages to rescue Harry. It shows the transformation of their relationship from rivals to something more like protectors of each other.
Their relationship often develops into a deeper, more trusting bond. Hermione's act of saving Harry makes him see her in a new light. He becomes more reliant on her, and she on him. For example, he may start confiding in her about his past abuse, which he never did before. This sharing of secrets brings them closer.
One example could be a story where Harry is verbally abused by some of his classmates in Hogwarts. Hermione steps in, using her quick wit and magic skills to defend him. She might cast a spell that makes the abusers' voices disappear when they try to say mean things. In this fanfiction, Hermione becomes Harry's protector, not just from the bullies but also from his own self - doubt that the abuse has caused.
Bankotsu and Kagome fanfiction is interesting because it combines two very different characters. Bankotsu is often seen as a rough and tough warrior, while Kagome is more gentle and spiritual. A fanfiction could play on this contrast, for example, having Kagome's kindness soften Bankotsu's hard edges.
Kagome would probably be shocked at first. Then she would start yelling at Inuyasha, demanding to know why he's doing this. She's not the type to just sit there and take it.
Inuyasha would likely become more protective. He's always been protective of Kagome, but with her pregnant, it would be on a whole new level. He might not let her go on dangerous missions as easily. Kagome, on the other hand, would probably get frustrated with his over - protectiveness at times, but also appreciate his concern deep down.
Inuyasha would probably be overprotective. Given his rough - and - tumble nature, he'd be constantly on guard to keep Kagome and the unborn baby safe. He might not fully understand all the aspects of human pregnancy, but he'd do his best. For example, he'd be extra vigilant during her travels between the modern world and the feudal era, making sure no harm comes to her.
Sakura could also be an ally. As a medic - ninja, she could help Kagome if she gets injured. And Sakura is used to dealing with strange situations and new people, so she would be open to helping Kagome.
