Nichijou primarily centers on the daily antics of a trio of childhood friends—high school girls Mio Naganohara, Yuuko Aioi, and Mai Minakami—whose narratives soon intertwine with those of the young genius Hakase Shinonome, her robot caretaker Nano, and their talking cat Sakamoto. With each passing day, the lives of these six, along with the many people around them, experience both the calm of normal life and the insanity of the absurd. Walking to school, being bitten by a talking crow, spending time with friends, and watching the principal suplex a deer: these are all part of a day's work in the extraordinary everyday lives of those in Nichijou.
