Now there are seven Nanas!! Everything about her has been multiplied by seven. There's a grumpy Nana, a giggly Nana, a crybaby, a slowpoke, a cool Nana, and a Nana who's just a little strange in addition to the original Nana - but they're still all Nana. She’s got seven times the problems, seven times the hopes and seven times the love for that cute boy Yuichi.
How can Nana possibly compete with herself and what are her parents going to say when they find out that they now have seven daughters? Whoever said that seven was a LUCKY number?
