**Height:** 162 cm (5'3")

Contrary to her flashy looks, she is surprisingly pure. She cannot deal with men. She believes kisses are special, and they should not be swapping and kissing so casually. In contrast to Haruko, she does poorly in her studies, but is good at cooking. She is also allergic to cats, and is envious that her friends have siblings, as she is an only child.

Two girls, Ichinose Haruko and Nikaido Natsuko, bump into each other by accident, resulting in a kiss and them swapping bodies. The only way to swap back is to kiss again...<br/><br/>
