List of Kiss×sis chapters

The Kiss×sis manga, written and illustrated by Bow Ditama, is a seinen publication that premiered as a one-shot in the January 2004 issue of Bessatsu Young Magazine, a bimonthly periodical circulated by Kodansha. The story, a comedic slice of life, centers on Keita Suminoe, a fifteen-year-old middle-turn-high school student who is the frequent subject of his sixteen-year-old stepsisters' romantic attention.

Kiss×sis was then serialized in Kodansha's now-defunct bimonthly Bessatsu Young Magazine from December 19, 2005, to August 11, 2008. It was then transferred to Weekly Young Magazine, being serialized from September 29, 2008, to December 7, 2009. It was transferred to Monthly Young Magazine (rebranded title of Bessatsu Young Magazine) on December 9, 2009. It was on hiatus between the August 2013 and January 2014 issues. The manga finished after 17 years of publication on September 21, 2021. Kodansha collected its chapters in twenty-five tankōbon volumes, released under their KC Deluxe imprint, from September 6, 2007, to November 18, 2021. The manga is also licensed in Taiwan by Sharp Point Press.

It was announced in June 2008 that an animated adaption of Kiss×sis would be produced by Feel. On December 22 of that year, the first OVA was released, bundled with the third volume of the manga, directed by Munenori Nawa. Subsequent releases were packaged with subsequent volumes of the manga. The 12th and last episode was released on April 6, 2015 with the fourteenth volume of the manga.

In addition to its domestic release, the manga is also licensed for distribution in Taiwan by Sharp Point Press.
