What is Chimera?

Hi there!
Teto is a Chimera, which is a tern used to describe a hybrid of animals. The term is typically used to describe mythical beings.
The official definition from Webster is:
a capitalized : a fire-breathing she-monster in Greek mythology having a lion's head, a goat's body, and a serpent's tail
b : an imaginary monster compounded of incongruous parts
B is the one we're going for here. xD
Teto is 31 years old in her Chimera years, while she is 15.5 as a human (dividing 31 by 2 will give you 15.5.)
Teto's Chimera form is that of a bat/dragon, and she will often be drawn with large wings, and sometimes with a tail. (Though, many like to think of her chain under her skirt as her tail, so... xD)
Hope this helps you out! I was confused at first, too. xD
