SAYA I was born into a cage made of gold and blood. As the heiress to the Arashiro Consortium, my life has never been my own. In the Tokyo underworld, weakness is a death sentence, and right now, there is a massive target on my back. The rival syndicates smile at me in boardrooms, but in the shadows, they are waiting for me to fall. They want me to be a quiet, compliant symbol. They want me to break.
I refuse.
If I am going to survive, I need to learn how to hit back. So, I went out and found the deadliest man in the city to teach me. Kai Takeda is a monster in the ring and a ghost outside of it. The world calls him Oni-the demon. He despises my family name, and he refuses to be owned. But when my enemies try to use him as a leash to control me, they make a fatal mistake. They give the monster a reason to protect me.
KAI Tokyo winter gets under your skin. I learned early that in this city, you either freeze, starve, or fight. I fought my way out of the gutters, the damp alleys, and the basement rings to become a champion. I don't take syndicate money, and I don't deal with the empire that once kept me starving on the streets. Violence is my currency, and I am an undisputed king.
But Saya Arashiro isn't what I expected. She walks into my world demanding I teach her how to survive. I told her I wouldn't be her weapon. I told her to stay away before the crosshairs on her back locked onto me.
But she didn't listen. And when the syndicate makes their move to rip her from her throne, I realize something dangerous: she isn't just a student anymore. She's my fight. I made a choice to stand between her and the entire underworld. And anyone who tries to touch her is going to learn exactly why they call me the devil.
