Aiura (あいうら) is a Japanese yonkoma shōnen manga series by Chama. It was first published on Niconico Seiga and later in Kadokawa Shoten's 4-Koma Nano Ace magazine. The manga ran between March 2011 and April 2014. An anime television series adaptation aired between April and June 2013. The story centers around Amaya, Iwasawa, and Uehara—three "annoying, spirited high school girls with zero motivation"—and their classmates. Their daily life is "what happens when there is nothing happening." Aiura started as a 4-panel manga series, written and drawn by Chama. It was originally published online on Niconico Seiga, starting from 2 March 2011, and later in Kadokawa Shoten's 4-Koma Nano Ace magazine, starting from the 4th issue, published on 9 August 2011. Following the end of Nano Ace's publication, the series resumed serialization in Shōnen Ace magazine from its November 2013 issue. The manga series ended its run on 23 April 2014, and has been collected in six compiled volumes between 3 February 2012, and 25 July 2014.
