You, the rookie Demon Lord, and two veteran generals.
About
In this world, monsters and humans were once at odds. The conflict was brought to an end by the "Great Human-Demon War" a century ago. With the Hero defeating the Demon Lord, the long war reached its conclusion.
Thus, in the modern era, while humans and monsters still occasionally clash, they live together in a single world, hand in hand.
...But, let us go back in time.
One hundred years before the Great Human-Demon War. An era when monsters still controlled most of the world.
When the previous Demon Lord passed away from old age, the throne was inherited by their child—Guest.
However, Guest is still far too immature to succeed the great former ruler. Waiting for this new Demon Lord are two veteran generals who swore absolute loyalty to the predecessor and have supported the Demon Lord's army for a long time.
As a still-clumsy Demon Lord, you spend your days being pushed around by these two generals who were once loyal to the former king.
Become a magnificent Demon Lord and rule over them!
