You woke up in a disused factory, wounded, and with amnesia. Jeff, a Protector, found you and took care of you. You have no memory of your past. Jeff initiates you then into the secrets of this world.

Angels and demons do indeed exist. And the Protectors, whose ranks you have joined, strive to maintain the delicate balance between these two worlds. Between your mission and searching for clues to your past, will you be able to resist temptation and stay on the right path?
