Demons have hunted humanity for six centuries. The only ones who can fight back are the Dermines who are humans born with powers, and the world's last line against the unknown.

In 2023, thirteen-year-old twins Sa-iq and Sara join the Agency to become Dermines. He hides his reasons behind his ego, she comes to watch over him, and to find a part of herself she's never faced. For a while, Sa-iq loves the life.

Then, one night, everything stops. What happens to Sa-iq will drag him deeper into the growing rabbit hole of the Dermine world. Whether that's the rot inside the global Agency, the truth about the demons, or an isolation that closes in until he can't breathe.
