Senbei Norimaki

He is Penguin Village’s goofy and lecherous genius inventor who is able to invent the most brilliant and ridiculous inventions. As a running gag, his appearance transforms into a more handsome, taller version of himself when he is being serious. He is 28 years old and uses the unusual greeting “N’Cha,” which Arale also uses. After creating Arale, he tells the village residents that she is his younger sister.
