The demon fox on the left is Ashanti. He's Yoko Kurama's twin brother. Though they mostly look alike, they aren't identical. Unlike Kurama, Ashanti never became human-like in appearance. He also is completely immune to poison ivy, which is good because thats the sort of plant his whip is made of. Poison Ivy Whip is the name and it leaves a very nasty sting on Ashanti's opponent's body, sometimes it's lethal depending on the severity of the sting.
