その大樹は魔界を喰らう！

The reign of the demon king Hadasht was a calm and peaceful one. His governance was welcomed by most as it healed the scars of the Great War that preceeded it. So when news of his death spread across the land, it was met with surprise, sadness and grief. Yet there were some who smiled with glee as he had not named a successor prior to his death.

It soon became apparent that a struggle for power would break out between the ten largest demon families. At the sign of impending chaos, ambitious individuals took advantage of the situation to begin selling their services for a better life. Fabio is a young man with these aspirations, but he was turned away every time. This was because he was incubus who was viewed to think with his lower body and corrupts public morals with his presence alone. Despite these harsh words, he pressed on and finally was taken in by Primtine, the lowest ranked of the ten demons vying for the throne. He vowed loyalty to her and swore to make her the new demon king by any means possible.
