Bet you didn't know this, Youko Kurama has a twin brother. His name is Ashanti. Well you wouldn't really know because he's an OC of mine that I've made for my YYH fanfictions.

Name: Ashanti
Age: 1000(or whatever Kurama's age is, since they're twins.)
Hair: Red
Ears and Tail: Red with black tips
Eyes: Gold
Outfit: Black
Weapon: Poison Ivy Whip (That's the plant that's in his hand. Ashanti is completely immune to the poison ivy's toxins. The whip stings his opponents mercilessly. The enemy dies a very painful death.)
More information: Unlike his brother, Ashanti was never given a human facade. He's always been in demon form. In order to keep others from confusing him with Kurama, Ashanti made his hair red and wears black.
