During the feudal era war develops on several kingdoms and territories, and Ryuuto leads one of the sides until one day his political enemies decide to set up a trap and send him to hunt a demon – which turns out to be a succubus known for killing several men already. The succubus falls in love with him – or at least with his lower part and energy – and decides to help him succeed in his military quest.
Ryuuto Hende is a soldier with unbelievable luck who was assigned to the province where a succubus is drying out men to death, and the local "first lady", who happens to be sexually frustrated. The H-parts show mostly a big-breasts theme and mutual love/appreciation. An OVA based on the WAFFLE game.
