Chaos and Annihilation

Xuan Chu failed to get hired as a cleaner at the newly opened office on the next street. On her way home, however, she stumbled upon a bizarre murder scene.

A metal man covered in spikes, literally; a fresh victim whose body was still warm; and an innocent bystander about to become the next victim.

She traded her life for another's, and in the end collapsed on the ground, barely alive. A strange young man saved her.

The surprising part came the next morning, when she woke to find that her fingers had turned into familiar-looking metal blades.

Xuan Chu calmed herself down and tried to look on the bright side: maybe this would make cutting pizza easier.

Her world turned upside down overnight, and then the office hired her at a generous salary.

On her first day at work, a colleague handed her a book with a smile: Blue City Urban Legends: A Complete Collection Through the Years.

Xuan Chu: ...Can I take it back?

The boss smiled warmly as he offered her a plate of heart-shaped cookies he'd baked himself. His voice was cold as the dead of winter: No.

At some point, [Gates] began appearing all over the world. Monsters from another world bared their sharp fangs at humanity, and every appearance of a [Gate] brought countless screams and deaths.

Humanity began to evolve. Awakened ability users banded together, fighting to defend their homes and dignity. Over time, they became what is now known as the [Ability User Management Bureau].

According to a certain pattern, this was the time when supernatural entities would surge in number.

Yet no one noticed that shadows had already begun to cover the world.
