''Seven of Seven'' (七人のナナ Shichinin no Nana) is an anime series that debuted in 2002. It's what happens when you let Yasuhiro Imagawa (''GiantRobo'', ''GGundam'') create a {{Shoujo}} series.

Nana Suzuki is an ordinary schoolgirl with a crush on one Yuichi Kamichika. One day, while trying to [[ThroughHisStomach bake a cake for Yuichi]], she stumbles on her scientist grandfather's secret experiment to separate the light of a rainbow into seven crystals. Naturally, the experiment goes awry, and [[LiteralSplitPersonality splits Nana into seven versions of herself]], each with her own matching rainbow crystal. Now, Nana must find a way to integrate the crystals together, or else all seven of her will vanish.

The Seven Nanas are:
* '''Nana''': The Original, or possibly the Responsible Nana. She uses the blue crystal.
* '''Nanappe''': The {{Bokukko}} Nana. She uses the red crystal.
* '''Nanakko''': TheSlacker Nana. She uses the orange crystal.
* '''Nanacchi''': The [[GenkiGirl Cheerful]] Nana. She uses the yellow crystal.
* '''Nanarin''': The cry-baby GamerChick Nana. She uses the yellow-green crystal.
* '''Nanasama''': The {{Bookworm}} Nana. She uses the green crystal.
* '''Nanapon''': The [[CloudCuckoolander Weird]] Nana. She uses the purple crystal.
