Volumes 1-71
Per AnimeNewsNetwork, Sigma began publishing in 2006. The covers for the earlier volumes need to be added but were not present on the Akaneshinsha website at the time of this wiki's creation, so the covers will need to be found elsewhere.

2013
The magazine published on a bi-monthly basis and the overall series numbering was included on the covers.

2014
The comic switched from including the overally series numbering on the cover and instead only named it after the month of the year.
