Koyomi Mizuhara

Koyomi Mizuhara, better known as Yomi, is one of the main characters from Azumanga Daioh. Her name was left unknown until the second volume, in which Azuma dedicated an entire strip to her in response to readers asking for her name. Her name is a pun, and alternately means read between the lines, in reference to her name being left "between the lines" until the strip in question. Koyomi is also Japanese for almanac.
