For Yuuko Aioi and her two eccentric friends, each day brings a unique experience. From stumbling upon a wrestling match between the principal and a deer to engaging in a chopstick battle over a sausage, the excitement never ceases.

In the world of Nichijou, daily life remains an endless roller coaster!
