When local teacher Midori Yamabuki receives an emergency summons to her home planet it turns out to be a trap devised by galactic warlord Dr. Mashirito, and it's up to Dr. Senbei Norimaki and a group of students (including his robot daughter Arale) to venture into space to save her. (Source: ANN)

Arale and company arrive at a nice location for a picnic. They soon discover a beautiful stone with strange powers. Before they know it, a dangerous pirate and his mysterious ship invades their peace and steals the stone. Now it is up to them to retrieve the stone before it is used by evil hands. (Source: BakaBT)

In Penguin Village, humans live alongside talking animals and objects. Senbei Norimaki is one of these humans, and he's an inventor with the lofty dream of creating the world's best robot girl. The product of his efforts is Arale, but depending on your definition of perfect, she's anything but! Not only is Arale severely nearsighted, but she also has no common sense! At least she has super-strength, though that often proves to be a setback as well. Although she means well, Arale only causes trouble for her neighbors in the whimsical Penguin Village!

Professor Senbei finds a videotape of his deceased father providing instructions on how to create a love potion. The main ingredient is a tear of the evil Gyaasuka Daimao who lives at the Wonder Island. To retrieve it, Senbei takes Arale and Gatchan on a wacky adventure. (Source: ANN)
