Uh-oh! Soleil drank some tasty-looking Juice That Makes You Evil and turned into a greedy vampire bunny!  
Her name is Countess Lalune, and she may not bite, but she WILL smooch any cute girl who fails to resist her vampiric charm.  
And it’s not their blood she wants to drain, either…
 
(To clarify: instead of fangs, Lalune’s lips are the key to her power.  
She can siphon a person’s body mass by kissing any exposed body part, causing the victim to gradually shrink in size as she enhances her own assets accordingly.  
What happens next depends on their cooperation…)
