Rules! Rules dictate everything from birth to death! But what happens when there are no more rules? In a world where only money and family background mattered, Ryan struggled at the bottom of the barrel without as much as a single chance to stand up. However, things changed when the world started evolving. Strange creatures began appearing and all that was alive started mutating. While people gained special abilities, animals turned into ferocious monsters. And in the midst of this chaos, Ryan received a special notification. Ding. Scanning complete. Criteria fulfilled. Demon System Initializing Ding. Do you wish to accept this curse? Watch as Ryan conquers all his enemies and becomes the supreme demon overlord wreaking havoc on the world that had once abandoned him!

Shizuku, a normal girl who just so happens to like other girls, was in a locker room with her classmates when she and the others were suddenly summoned to another world.

Not wanting to have anything to do with the people who summoned her, Shizuku asks the goddess, who gives out classes and gifts for a few extras.

With no way home, Shizuku becomes a Fallen or, more specifically, a Vampire. The Fallen, who is hated by the very people who summoned her, has no place in the list of heroes who are supposed to protect the Holy Kingdom and the world. 

Kicked out and on her own, with no understanding of her new world and with a prophecy of destruction facing it, Shizuku sets out to make a place for herself in this new world she has been summoned to. 

Will Shizuku be able to survive in this new world, or will she end up losing everything, including her life?
