The Greatest Demon Lord Is Reborn as a Typical Nobody, Vol. 6 (light novel)

The incident in Megatholium has ended with severed ties between the five
superpowers. On the surface, it seems like things are disturbingly quiet...until tensions
mount between Laville and another kingdom, and Ginny is taken as a hostage from
her own home. It’s up to Ard, Ireena, and Sylphy to save her, but things rarely go
that well, especially when they involve their well-acquainted nemeses: Elzard and the
masked figure. It’s a race against time to rescue their dear friend!
