There could be a fanfiction where Inuyasha in his human form has to protect a village from a new threat. Since he doesn't have his full demon powers, he has to rely more on his wits and the help of his human friends. This would show a different side of his character, more vulnerable and yet determined.
Fanfiction.net is also a great place to find Inuyasha human form fanfiction. There are different categories and filters you can use to narrow down your search. Just be aware that the quality can vary, so you might need to read a few to find the really good ones.
Give the Okami in human form a backstory that ties them to their original form. Maybe they were cursed to be in human form as a punishment or they chose to take human form to better understand humans. Their actions should also be influenced by their Okami nature. For instance, they might be more in tune with the phases of the moon and act differently depending on whether it's a full moon or a new moon. Their speech could also be a bit more formal or archaic, reflecting their otherworldly origin.
Kagome is an obvious choice. She has a strong bond with Inuyasha already, and when he turns human, their relationship could take on new dimensions. She might have to be more protective of him, or they could have different kinds of interactions. Miroku is also interesting. His wisdom and his own goals could play a role in helping Inuyasha deal with being human. He could offer advice on how to handle the new situation, or he might have some knowledge about the cause of Inuyasha's transformation.
He might have a tall and imposing stature, with piercing eyes that still hold a hint of his otherworldly power. His hair could be a dark color, perhaps black or a deep shade of purple, and it would be neatly styled.
She would likely have long, flowing hair, perhaps a golden color like the sun, to represent her divine origin. Her eyes could be a bright, piercing blue or amber, full of an otherworldly intelligence. She would have a graceful figure, with a certain poise in her stance that makes her seem both approachable and yet somewhat ethereal.
Well, in fanfiction, Kurama's human form could be a really imposing figure. He might have long red hair, just like his fox form's fur color, and bright, piercing eyes. Maybe he'd be tall and muscular, with a sort of wild, untamed look about him, still carrying that powerful presence that he has as a tailed beast.
One common theme is the power of their relationship. Their bond, which is a mix of friendship, love, and mutual respect, is often explored. For example, how they support each other in battles against demons.
There is also 'The Bond of the Jewel'. This fanfiction delves deep into how the Shikon Jewel affects their relationship. It shows how they rely on each other to protect the jewel and in the process, their bond grows stronger. It has some great character development for both of them.
