On New Year's Day, Nana Suzuki is disappointed when she has to share her holiday allowance with her six clones. However, the hyper-intelligent Nanasama hypothesizes that they can use the invention that cloned Nana to increase their allowance. Things don't go so smoothly this time either, though, as chaos ensues when Nana multiplies again—this time into 49 copies!
