Perhaps Inuyasha discovers a hidden portal. He enters it out of curiosity and ends up in the past where he witnesses his father Inutaisho and mother Izayoi meeting. This could be a moment filled with shock and realization for Inuyasha as he sees the origin of his own existence.
They could form an unexpected bond. Inutaisho and Izayoi might see Inuyasha as a strange but endearing figure. Inuyasha, on the other hand, could gain a new understanding of his parents. For example, he might see the love that his father had for his mother, which was something he may not have fully grasped before.
The theme of power inheritance might be explored. Inutaisho could pass on some of his unique powers or abilities to Inuyasha, and this could be a central part of the story.
In this fanfiction scenario, Inutaisho could guide Inuyasha in his journey to become a better demon. He might teach Inuyasha about the history of their kind and how to control his powers more effectively. This could lead to Inuyasha having a new - found sense of purpose and growing in strength and character.
Authors often describe a sense of shock and recognition. For example, Inuyasha might be stunned for a moment, his eyes widening as he sees Kagome. There's a pull towards her that he can't deny, and he might feel a mix of anger (from past experiences) and a strange longing. Kagome, on the other hand, might feel a sense of relief and excitement, with her heart racing.
Another scenario could be that they meet in a parallel universe where their roles are reversed. Kagome is the half - demon and Inuyasha is the one from the modern world. This would lead to a lot of character development as they have to adapt to their new identities and figure out how to deal with the situation.
In a 'Kagome Meets Inutaisho' fanfiction, their meeting could be filled with tension. Kagome, coming from a different time and with her own set of beliefs and values, might initially clash with Inutaisho. However, as they get to know each other, they could find common ground. Inutaisho might be intrigued by Kagome's modern - day thinking and Kagome could learn more about Inuyasha's past through him. This encounter could also potentially bring about a new alliance or a deeper understanding between the two characters.
In a fanfiction, Naruto could inherit some of Inutaisho's traits. For example, he might gain enhanced senses like super - hearing or smell. This would change the way he approaches battles and missions. He could use these new abilities to his advantage, perhaps even being able to sense traps or hidden enemies before they become a threat.
The storyline could develop with them facing some sort of threat to the pregnancy. Maybe an enemy from their past resurfaces, seeing the unborn child as a way to get revenge. They would then have to fight to protect the pregnancy.
Sesshomaru would raise the baby with a combination of discipline and protection. He would protect the baby from any threats, using his powerful abilities. At the same time, he would discipline the baby when it made mistakes, teaching it the ways of the demon world. Inuyasha, on the other hand, would add a more carefree and emotional touch to the parenting, creating a balance in the baby's upbringing.
Some popular Inutaisho and Kagome fanfictions include 'Echoes of the Past'. It tells a story of how Kagome discovers secrets about Inutaisho that have been long forgotten. The story is filled with mystery and adventure. Another one is 'Shared Destiny' which shows how they both are on a path that seems to be leading them towards each other, no matter how different their worlds are. 'The Timeless Bond' is also a great read as it explores the emotional connection that could potentially exist between Inutaisho and Kagome.
