Seven of Seven (七人のナナ, Shichinin no Nana) is an anime TV series created by Yasuhiro Imagawa (Giant Robo, G Gundam) and produced by A.C.G.T.

Due to production schedules, the manga adaptation, illustrated by Azusa Kunihiro, started serialization in Akita Shoten's Shōnen Champion on November 8, 2001, two months before the anime premiere.

It relates the premise of the series, where Nana has split into seven different sides of the personality due to an accident with a crystal.

After years of failed attempts and crazy inventions, such as a VCR toaster and vacuum cleaning mouse catcher, he finally discovers a way to make such a crystallized rainbow.

That is when Nana, who was searching for the microwave in an attempt to bake a chocolate cake for Yuichi (her crush), opened the door before the crystal had fully hardened and caused an accident.

This leads to a chase between the original Nana, and the new six sides of her personality who are all fighting as they fly and destroy parts of town over who will give the cake to Yuichi.

But once they're finally done fighting, they once again prove that all seven Nanas are still the same person as they all find themselves too nervous to approach Yuichi and actually give him the cake.

After they had settled on their roles, the 7 Nanas also face the fact that if the crystals aren't reintegrated within a year after the split, all 7 of them will disappear.

He tells her the gypsy woman's warning, to never let the light of the moon pass through the crystal.

Frog's manga artist, Mine Yoshizaki, created the character concept designs for Seven of Seven.
