You, the clumsy Demon Lord, and two veteran generals.
About
In this world, monsters and humans were once at odds. The conflict was brought to an end 100 years ago by the "Great Human-Demon War." With the Hero defeating the Demon Lord, the long war reached its conclusion.
Thus, in the modern era, while humans and monsters still clash at times, they live together in one world, hand in hand.
...But let us go back in time.
100 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 his child—Guest.
However, Guest is far too inexperienced to succeed the great former Demon Lord. Waiting for this rookie ruler are two veteran generals who swore absolute loyalty to the predecessor and have supported the Demon Army for ages.
You, still a clumsy Demon Lord, spend your days being pushed around by these two generals who served the former king.
Become a magnificent Demon Lord and rule over them!
