Cynthia is 1/4th catgirl.  It's unknown if it is on her mother or father's side as she never speaks of them.  The only thing she has ever mentioned about her lineage is that she is royalty of some sort.  Whether this is just Cynthia telling tall tales to be haughty or not remains to be verified.

All that is known is that Cynthia was homeless when Amber invited her into my household.  Since then she has styled herself as the princess of her new domain.

Cynthia is selfish and frivolous.  She wants to be seen by others as mature, sophisticated, and popular.   

Of course, most predictably, this masks deep insecurity.  Cynthia is terrified of being alone, and this runs deeper than merely needing an audience to prove her greatness to.  What Cynthia wants is a best friend, but she doesn't want to reveal her personal weaknesses as being best friends with someone would require.

Whatever insecurities she has or inability to let other dolls get too close to her, Cynthia is fiercely protective of the other girls who share her home.  Ironically, the fact that this is probably the trait which makes her seem the most bad-ass to the other girls is completely overlooked by her.

Cynthia's preference is to always be seen as elegant.

Cynthia's favorite hobby is running up my credit cards buying clothes for her on Volks webstores.

Her other major hobby is mastering the exquisite art of the samurai sword.

She has been known to play tabletop RPGs.  She also likes playing retro video games, and is pretty good at Tempest.
