A while back, I had a Sonic character OC.
Her name was Selena Rose and she could summon wolves. One of her many wolves were Blackness, and another one she had was something like Dark Rain. {I don't know, it's been years and I have forgotten} Either way, when I saw this lineart I was like "OMG I HAVE TO USE IT AND MAKE IT A BLACKNESS WITH HER CUTE LIL PUPPY WITH DARK!" And... yeah. I don't exactly remember where the white came from. I think it's from the puppy's grandmother.
I do not own this lineart! A link to it is here
