(Sorry, everyone.)
An unexpected player has entered the board of gods and demons.
The player and the pieces fight side by side, determined to protect everything they hold dear.
Nameless Knight: We are willing to become kindling and light the way ahead. Humanity shall never perish!
Cursed Vampire: If it's for you, what does betraying the gods matter?
Demon Cyborg: My father once told me that Kamen Riders are heroes. I want to become a Kamen Rider!
God-Slaying Wolf: Spirits? Gods? What do they have to do with me? All I want is to rip out the throats of those filthy bastards!
Bearing the hopes of countless heroes, he wagers his own fate and the fate of the world.
"I will be the one to win this game!"
Simply put, this is the story of a man who obtains "pieces" through a game and plays against the gods, growing from a novice into a mature man.
(Planned heroines include a doll girl, a beast-eared girl, a vampire, and a magical girl.)
