Shichinin no Nana: Oshougatsu da yo! 7 x 7 = 49-nin no Nana?

The series follows Nana Suzuki, whose life takes an unexpected turn on New Year’s Day with the arrival of her six clones. Guided by the logical and calculating Nanasama – seemingly a more advanced iteration of herself – Nana embarks on a series of increasingly complex experiments centered around the cloning technology that created them. Initially motivated by a desire to improve their financial situation, these experiments rapidly escalate, resulting in a cascade of unforeseen consequences.

The narrative explores themes of identity, individuality, and the ethical implications of scientific advancement within a vibrant, contemporary setting. As the number of Nanas steadily grows, the story examines the challenges of maintaining personal autonomy and navigating interpersonal relationships amidst overwhelming sameness. The anime presents a unique blend of slice-of-life elements with speculative fiction, offering a thoughtful examination of what it truly means to be an individual.
