I tighten my grip around Rebellion’s hilt—and without hesitation, I drive the blade straight through my chest.

Pain explodes outward, sharp and blinding, but I don’t scream. I welcome it. The steel sinks deep, and the world seems to hold its breath as my blood runs hot along the blade. My heartbeat stutters once… then slams back harder than before, like something far older has just woken up inside me.

I feel it tear loose.

Power floods my veins, violent and overwhelming, shredding whatever fragile line was left between man and devil. My body convulses as demonic energy ignites from within, bones reshaping, muscles burning as if forged anew. I can feel my humanity cracking—splintering under the pressure—but I don’t fight it.

I lean into it.

A roar rips out of me, raw and unrestrained, as wings of pure crimson force burst free from my back. The ground beneath my feet fractures, unable to bear my weight anymore. The air thickens, crushed by my presence alone. This isn’t just strength—this is judgment.

My vision sharpens, glowing red, every heartbeat thundering like a war drum. I can feel the power bleeding off me in waves, scorching everything it touches. Yet through it all, my mind is clear. Focused. Alive.

I pull Rebellion free from my chest, the wound sealing instantly, leaving nothing but heat and smoke in its wake. A grin curls across my face—slow, dangerous, unmistakably mine.

So this is it.

Sin Devil Trigger.

And now… let’s see who’s brave enough to attack my princess.
