    Ayumi is a normal human girl without supernatural power, but her butt isn't a normal one.

    When Ayumi was a child, she went to a mysterious abandoned gardon, and she met many walking flowers there. Little Ayumi played with those beautiful beings all day long, she was so happy and excited.

    In that day, Ayumi wore a burgundy skirt. When she jumped up and down, her skirt fluttered around her hips, made it looked like a butterfly with waving wings. The scene impressed Ayumi a lot, she wished she could be a butterfly and play with those flowers forever.

    Finally Ayumi has grown up, and her reasonable mind forgets that day. However, her heart doesn't forget the feeling and the wish, she wants herself to come back to the wonderful gardon subconsciously.

    The strong affection drives Ayumi to become a butterfly to visit her flower friends-- or at least, a part of Ayumi. When Ayumi sleeps, if she wore a burgundy skirt, her butt would "take off" and carry her affection to fly to the garden. Ayumi's separated butt will transform itself to be a butterfly fairy, it's Buttfly.
