Zene looks pretty much like a normal human being. However, there is more to her than her physical appearance. By night, she mysteriously morphs into a butterfly. Even though Zene isn't quite sure of her metamorphosis, she enjoys her time as a butterfly more than anything else. She adores flying around with her bunch of butterflies, undisturbed and free. However, there are times when Humans gets in her way; trying to trap her up in a bottle. This explains why she loathes Humans.

She lives with Munkey; her stuff monkey that she found lying at the back alley somewhere near her house location. Ever since then, Munkey has been her only companion. Together, they live in a weird-looking hut at a very isolated place in New York.

Zene's existence started during the Art Nouveau period. During that era, board games and toys were in mass production; and Chess was one of Zene's favourite games. It is the only other possession she treasures and is proud of. Hence, she forces Munkey to play a game with her almost everyday.
