Nobody talks about this one. Seven versions of the same girl each want the same boy, and the show doesn't use that for cheap gags, it uses it to ask what happens when you can't decide who you actually are. The dub carries the entire weight of seven distinct voices that somehow sound like the same person fractured into different moods, different choices, different futures. By the second half, when the clones start colliding with what the original Nana has to become, the show has already made you care which version gets to be real.
Nana's ordinary high school life explodes when her eccentric grandfather's latest invention malfunctions, accidentally creating six identical clones of her. What was supposed to be a harmless experiment becomes immediate chaos: all seven Nanas exist simultaneously, each with their own personality quirks and, most problematically, romantic feelings for the same boy. Managing one teenage crush is hard enough. Managing seven becomes a comedy of errors that spirals across school hallways and into increasingly absurd situations. The clones aren't perfect duplicates. While they share Nana's face, each one develops distinct traits and opinions that constantly clash. Their collective pursuit of one guy creates misunderstandings, jealousy, and slapstick confrontations that nobody saw coming. Meanwhile, keeping the clones secret from the rest of the school proves nearly impossible as their cover gets thinner with every close call. This is lightweight fun that doesn't pretend to be anything deeper than what it is: a premise designed to generate laughs through chaos and confusion. The chemistry between the seven versions of the same girl drives the comedy forward, while the central love triangle multiplied by seven keeps the romantic tension unpredictable.
