Redemption could come through a series of trials. Inuyasha could face challenges that test his loyalty to Kagome. With each successful trial, he would earn back Kagome's trust. He could also make amends by helping Kagome achieve something she deeply desires, like finding a way to fully close the well between her world and the feudal era, which would show his commitment to her and their relationship.
One way could be through self - sacrifice. If Inuyasha were to put himself in great danger to save Kagome from an even greater threat, it would show his true feelings for her. He could also openly admit his mistakes and beg for forgiveness, vowing to never let his past feelings for Kikyo cloud his judgment again.
One possible reason could be a misunderstanding. Maybe Kikyo was in some kind of danger and Inuyasha's actions to save her were misconstrued as betrayal. Another reason might be that Inuyasha was influenced by some external dark magic that clouded his mind and made him act against his normal feelings for Kagome.
He might also become more patient. Usually a bit hot - headed, but with Kagome pregnant, he'd have to learn to be more calm and understanding. For example, when Kagome has mood swings due to hormonal changes, Inuyasha would have to control his temper and be more supportive instead of getting frustrated.
Well, in some fanfictions, Inuyasha might hurt Kagome's feelings by being overly possessive. For example, he could get jealous when Kagome talks to other male characters and then say something harsh. Another way could be that he doesn't trust Kagome's judgment at times, like when she tries to come up with a plan to deal with a demon and he dismisses it rudely, making her feel unappreciated.
I recommend the following Doujin novels to you, I hope you like them: 1. "Half-demon I rushed to the Soul World with broken iron teeth", a story that traveled through the world of Inuyasha and Death. In order to protect Kagome, the protagonist, Makoto Hojo, turned into a half-demon to fight against the powerful Void. 2. "Inuyasha: The Age of Chiyuki". The story was about a young man who had lost his life and returned to the Warring States Period. It became a derivative doujinshi novel of Inuyasha. 3. "I, Inuyasha!" The protagonist who had transmigrated into Inuyasha didn't have broken teeth. When he woke up, he found that he had become the city lord. The general Yue Huangquan and the divine spring Yunya, who were in love with the monster, also appeared. The above is my recommendation. I hope you like it. Muah ~
In some fanfictions, Inuyasha and Kagome might have an argument that actually strengthens their relationship in the end. For instance, they might disagree about how to deal with a certain threat. But through the argument, they both come to understand the other's perspective better. Afterward, they are more in tune with each other's thoughts and feelings, and their bond becomes even more unbreakable.
Sesshomaru is an enigma. In fanfiction, his cold exterior and his pride as a full - demon are prominent. He initially sees Inuyasha as a weak half - breed, but as the story progresses, he may come to respect Inuyasha's growth. His relationship with Kagome can also be an interesting aspect. Sometimes he's indifferent to her, but other times he might be intrigued by her powers and her ability to change Inuyasha.
Inuyasha is devastated when Kagome gets hurt. He blames himself, especially if he was supposed to be protecting her. He'll pick her up gently and try to find a safe place to tend to her wounds. He might also call for help from his friends like Miroku or Sango. He'll stay by her side until she recovers, constantly on guard against any further threats.
Some great Inuyasha and Kagome fanfictions include those that focus on their adventures after the end of the series. For example, 'A New Beginning' which shows them building their life together in the feudal era. It has really good character development and stays true to their personalities.
In fanfiction, their romance can be very intense. Writers often show Inuyasha being more protective of Kagome. For example, he might fight off stronger demons to keep her safe. This portrayal emphasizes his deep love for her and his willingness to risk everything for her well - being.
Well, in some fanfictions, Kagome might hurt Inuyasha by saying mean things. For example, she could bring up his past mistakes or insecurities in a cruel way during an argument. This could really wound his pride and his feelings towards her.
