Hierarchy of Laguna
"Joys are members of the Seraphim class within the angelic hierarchy's First Sphere. These beings have broken free of any physical conception of form and have become truly spiritual.

Their body is as free as a flowing river, and it takes shape only on a temporary basis. Joys may take the shape of the human feminine form, but can also shape-shift, or even separate into multiple sentient forms, at will."

Trivia

 * When looking at the picture of Joy in the file inside Hierarchy of Laguna file book, the three Joys spell the word 'Joy' with their bodies.
