At 28 years old, Nanase is the eldest sister, who works as a data processor in an office. Her power is the Earth Dance of Flowers, the ability to summon a whirlwind of flowers, to absolutely no effect. There are many hints that she would like to be a transsexual. Her name is derived from nana, the Japanese word for &quot;seven&quot; (for which another word is &quot;shichi&quot;), thus she is the 7th of the Sisters.     from wikipedia
