Princess

A cute little critter with more parts than the average chimera! Princess  is actually an extension of a parasitic hivemind that functions by  promising people the fantastical dream of becoming a hero, only to have  their magic and lifeblood sapped from them over time.

Princess herself is a very cheery kinda gal, always boosting her current  host's motivation to continue on to the Queen for a "special  mission" (their untimely death)

A good char comparison is Kyubey from Madoka Magica if that sparks any inspiration in you!
