Comic Kairakuten is published on the 29th of the month unless the 29th is a Sunday or a Public Holiday in which case it may be published between the 27th to the 30th of the month.
Over the years it has featured many famous illustrators and manga artists including, LINDA, Keito Koume, Hanaharu Naruco, Napata, Key, Michiking and Homunculus. Many of the early covers were drawn by Murata Range who still draws a monthly illustration for the magazine in his futuregraph feature.
