The spinoff manga of Mamare Touno’s Log Horizon light novels launched on Enterbrain’s web manga site Air Raid in 2012, but transferred to the new B’s-LOG Comics website in 2013 when Air Raid and Enterbrain’s Comic B’s-Log Kyun! were combined.
Yen Press publishes the Log Horizon light novels, as well as the Log Horizon: The West Wind Brigade spinoff manga, in North America.
The official website of Kadokawa’s Enterbrain brand is listing the sixth volume of Souchu’s Log Horizon: Nyanta’s Fortune Recipe (Log Horizon: Nyanta Hanchō Shiawase no Recipe) manga as the last.
Kadokawa released the 10th volume of Touno’s Log Horizon novel series with illustrations by Kazuhiro Hara in September 2015.
