Najimi Tenkuuji
Kakeru's childhood-friend and classmate, whose charm point is her "antenna" hair which changes form according to her mood. She's an heiress to the Tenkuuji group of companies and she holds a romantic feeling toward Kakeru. She's gentle and easy-going, but her weird sense of imagination tend to warp her into her own world. She has the history of being saved by Kakeru from being kidnapped. She also has the tendency to become a Kuribo look-alike (from the Super Mario series) when struck by jealousy; she starts kicking Kakeru's calf. (source: Wikipedia)
