Could इनुयाशा and Yoko Kurama be brothers?

Um no because Yokou Kurama is a pure spirit लोमड़ी, फॉक्स and इनुयाशा is a half-Inuyoukai (dog demon) they just look similar, but they are NOT related.

I would say no. Yoko Kurama is way cooler. But they are pretty similar at times...

As Stated Yoko Kurama is a pure spirit लोमड़ी, फॉक्स and InuYasha is a completely different type of "demon" than Kurama. Just because they both look similar doesn't mean that they're related..

they could be brothers या just the species
