Miraku Chan is a girl oyster with a cyan-coloured body and a butter-yellow shell. One day while she was sleeping under the sea, a little pink shell floated near her and got lodged onto her head. She tried but could not remove the little pink shell. As time goes by, she grew to like the pink shell more and more. It made her look beautiful and 'spe-shell'.
Miraku is often forgetful (blur-blur) but she’s an optimist. And she likes to cook and doll herself up.
