Ikki was a monthly manga magazine published by Shogakukan in Japan. It focused on underground or alternative manga but also had popular hits. Originally launched as Spirits Zōkan Ikki in 2000 as a spin-off from Weekly Big Comic Spirits, it became a standalone monthly magazine in 2003. An online English version called SigIkki was launched by Viz Media in 2009, serializing selected titles from the magazine. After nearly 14 years of publication, Ikki ended in 2014 and was replaced by Hibana, which ran from 2015 to 2017 before stopping its publication.
