Succubus and the Last City [Final] By Developing Room

(translated from Dlsite)

Battle System
This is an original battle where you act in quick order.
It is a victory if you give pleasure to your partner and make him climax.
On the other hand, if you are made to cum, you will lose.
The change in facial expression when cornering an enemy,
There is a difference when you take off your clothes.

Defeat event
Even if you fall into the devil’s trap or lose the battle, the game will not be over.
The scene will shift to each character’s defeat scene, and then they will be returned to their base.
At that time, the losing character’s lines will change and the difficulty of the battle will increase.
