Helvetica Standard

Helvetica Standard is a 4-koma (four cell manga) random comical short that is self-contained, and generally outside the main story of Nichijou. In the anime, the only connection to the main story is that Yuria Sekiguchi is always reading this, and other characters like Sasahara are seen reading it too. However, many of the Helvetica Standards feature characters from Nichijou and are in the anime as regular shorts.

Its name is derived from the Helvetica font family, specifically the obsolete "Helvetica Std" font.
