Nanako Kobayashi, a 17-year-old teenager, has an ugly face who seems to not have a care for the world. One day, she got a call, only to be given two choices to answer a question. A devil suddenly appears, taking the form of her teddy bear. The devil is willing to grant her three wishes; each based on two options; What wishes will Nanako choose?

"Once upon a time I dreamed I was a butterfly,

fluttering hither and thither,

to all intents and purposes a butterfly.

I was conscious only of following my fancies as a butterfly,

and was unconscious of my individuality as a man.

Suddenly I woke, and there I lay, myself again.

Now I do not know whether I was then a man dreaming I was a butterfly,

or whether I am now a butterfly dreaming I am a man."

(Zhuang Zhou Meng Die (庄周梦蝶 ))
