A Light in the Dark

The year is 2200.
Depleted resources, unstoppable environmental destruction, growing food shortages, and an ever-increasing population has left this new century in a constant downward spiral.
The world was moving toward its end.
In the midst of such dire circumstances, many countries have collapsed or just barely cling to life.
But amongst all that misery and destruction, there was one single city that shone brightly and prospered.
“Commercial City”
A bustling metropolis of the future, run and controlled by corporations.
Play as Sana, a former prostitute, who is tracking down the mastermind of a terrorist organization for a life-changing 400 million bounty. Money is all that matters in this new world, and can be used to grease the gears of fate, or keep them from turning to avoid certain events… But there are other, more debauched methods that are available to a beautiful young woman in this depraved world.
Sana has a tough battle ahead of her to take down enemies to earn money and gather resources to upgrade her gear… Or fall into old habits to find an easier way forward. Sana’s stress level will influence many factors in the game, including events and her relationship with her boyfriend. Once her stamina has been depleted for the day, play as her boyfriend to “relieve” her stress levels, lest she have to seek out others to do it in his stead.

Driven by hidden instincts, the protagonist and his schoolmate enter a pact with a group of powerful Succubers, roaming the streets to gather energy. Will they fulfill their contract and achieve their ultimate dreams?

One day, Tachio, an ordinary office worker, is suddenly transported to another world overrun with dark monsters known as Yamimon.
In this strange world, he is attacked by Yamimon, but is saved by the beautiful dark hunter Kurenai, with striking red hair and large breasts.
However, the moment he comes into contact with Kurenai,
he fuses with her special battle suit, Gear.
Thus, Tachio fights alongside her as her suit during battles,
while searching for a way to return to his original world (while being made to take care of everyday things at home).

Our story starts when peace has finally taken hold of the world after the war. The former mercenary and dark elf Fornelia, battle-worn and looking for a place to die, saves a young man named Ruse from a monster attack.

Heroines who seek revenge for various reasons make wishes to the demon race in order to gain power.
It is your task to assist them in their revenge while gradually corrupting their hearts.
