Arale Norimaki is an android built by Senbei Norimaki, known for her naiveté, energetic personality, superhuman strength, and lack of common sense. Being the world's first perfect android, her only physical flaw is that she is nearsighted and needs to wear glasses. Senbei's mission is to convince the other citizens of Penguin Village that Arale is a human girl, which they appear to believe in, despite taking notice of her quirky behavior.
