Daimaou no OFF

Synopsis

Obscurite is a land of darkness where demons of all shapes and sizes roam. Durandra, the powerful but careless queen of the demon realm, is tired of battling with the recent surge of adventurers, who seem to be rapidly increasing in number these days. While she was taking a little nap, the dungeon was conquered...? The slapstick daily life of a besieged demon tribe is depicted in this JRPG-style otherworldly comedy!
