Dancing Doll

Original Form=

You wouldn't know it from her youthful appearance, but this ghost is actually an extremely refined dancer. A devoted student of dance, she's reportedly got thousands of dance videos stored inside her tablet PC. When it comes to appraising her skills, she ignores accolades and others' opinions, instead relying solely on her own judgment. Seriously: how old is she, again?
