It's been a LONG while since Vivi has gotten any attention, so I wanted to fix that, so I integrated a Ninetales form into her

The idea behind this isn't as a evolution persay, but a form that she can switch on and off from with her Necklace charm

She's also supposed to be Vampire-ish, so you'll see some small fangs sticking out and a bit of a missing ear, also the inspiration behind a "form" instead
