Hired as an Elite General, Dennosuke's first task is to negotiate a merger with the leader of the resource starved Ogre Tribe. Despite their suffering and the Ogre leader's stubbornness, Dennosuke works to find a way forward for the Demon lord's army. 

The Dark Lord gives Dennosuke a new task: to research the magical arts so that everyone can use magic even without the necessary power. And this time, he will have the help of the elusive Sylphid.
