There was no clear connection between Sanguine Red's novels," Tengen " and " Tengen 1 ", which could form an independent series. However, judging from the name, Tengen could be considered a follow-up to Tengen 1 because Tengen was usually used to refer to the first work in the series. However, this was not absolute, because the name connection did not necessarily mean that there was a direct causality between the works.
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.

Their speech could also be a bit more formal or archaic, reflecting their otherworldly origin.
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.

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.
