The White Bull
The story is based on the Greek mythological tale of Europa and the bull, where the white bull is the king of the Greek gods, Zeus, in disguise. Zeus, the sky and thunder god of the Olympic pantheon, often wore a disguise when romantically pursuing mortal women, so as to avoid the eye of his wife and sister, Hera.
Because I'm the Goddess
Zeus, the God who created Pandora, is a diminutive crowned child with a big ego and an even bigger mount, which he calls 'Kratos'. When his power was taken from him many years ago, it was broken up and scattered across Japan as 'Gifts'. His first attempt to retrieve them failed, and it took him so much energy to make her that he slept for a century. Upon awakening, he creates Pandora and sends her to Earth to do the job properly. She succeeds in Volume 3, defeating his previous Goddess and confronting him. Pandora plans to kill Zeus but realizes that without the Gifts and the power of chaos, Man has no will to live. She instead kills herself, and Zeus is forced back to Heaven to sleep for another hundred years.
