This is quite possibly his worst nightmare.
It doesn't matter that it's his king standing in front of him. The fact of the matter is that he's covered in extra strong Hollow bait and every last one of Zangetsu's neurons are on fire; a storm that sparks with the overwhelmingly powerful directive to eat. Lunge at him, puncture his jugular with his teeth, tear muscle from tendon and drink in the blood again and again until nothing is left to eat.
He takes a step back, looking as frightened as cornered prey. He can't, but he wants. His teeth ache to the gums with it. And Ichigo, stupid, beautiful, kindhearted Ichigo, steps forward to grab him and steady him and ask him what's wrong, and that only makes the craving worse. He's staring at Zangetsu with sorry, begging him to say something, but Zangetsu looks at him now and can only think of meat.
Meat. All he wants is meat. His teeth ache to sink into it. Well if it's meat that he wants, he thinks to himself deliriously, he'll get his meat, but not from his King. Never from his King. Instead, he brings his own arm up and bites through the soft flesh of his forearm.
He knows better than anyone that instincts aren't perfect. It's his own arm, and yet despite the pain, it's still meat. It's enough to fool his hunger. So he eats like a starving animal, tearing out his own veins, dying his face blue with his blood.
He'd threatened Ichigo with devouring him before, but that had always been an empty threat. A blade waved around, meant to encourage him through fear. If he truly hungers, he'd sooner turn those teeth on himself.

He knows exactly when it went wrong.
Urahara’s voice is still ringing in his head—don’t touch that, Kurosaki-kun!—but of course, it’d been too late. Bis hand had moved on its own, drawn to the faint hum of the tube, the soft glint of its contents. Half a vial’s worth of concentrated hollow bait spilling out to mist across his sleeve, soaking into skin before he could even wipe it off.
Now it’s thick in the air around him. Heavy. Sweet in a way that makes his mouth wet and his jaw itch.
It takes effort to shake it off.
But Zangetsu goes still on sight. Before Ichigo’s even set his keys down and closed the door. Ichigo freezes too.
It’s the kind of stillness that comes before movement. Every muscle tight. Every breath a hungry tremor. Ichigo can feel it through the air like a delicate static, it lifts the hairs on his neck and arms, drags at him like an invisible riptide.
“Hey...” He forces a half-smile, voice low, steady. He can see it now, the dark of Zangetsu’s eyes like a black hole sucking in light, the twitch at his jaw.
It’s… wrong. Ichigo reaches out anyway.
They’ve done this before. It was fine. Zangetsu kept it together.
He doesn’t get to finish. Zangetsu jerks back like he’s been hit. The sound he makes isn’t words, it’s a rasp, low and panicked.
Ichigo freezes. For one long, sick second, he doesn’t process what he’s seeing. Barely flinches at the cold spray of blood across his cheek. Then the smell hits. Copper. Salt. And that now familiar sound of tearing flesh.
He stumbles forward on reflex, one hand shooting out as Zangetsu’s teeth carve through his own forearm like a desperate animal trying to free itself from a trap. Flesh parts, rips, disappears down his throat. Ink blue blood slicks his face, spattering the floor.
Zangetsu doesn’t even look at him. His eyes are wild, locked inward, and Ichigo knows, knows, this is only going to get worse if he doesn’t—
The shift is instant. His body drops limp behind him, soul snapping forward. He’s moving before his human skin even hits the floor, crashing into Zangetsu hard enough to knock both of them down. The rug slides under their weight. His knee digs into Zangetsu’s stomach and hip as he pins him, one forearm braced across his throat where teeth won’t find it, the other grappling for the wrist that’s still trying to rise and tear itself apart on his mouth.
The words hit with force. His reiatsu flares without permission, flooding the room in pressure, flickering the light, flexing walls, cracking glass somewhere. He doesn’t look.
If it were just the arm, he’d be annoyed. Mildly put out. Disturbed.
This isn’t that. This is a devouring. An implosion of ravenous hunger.
“Zangetsu! You don’t get to do this—you hear me? Stop!”
Zangetsu thrashes under him, breath hitching, the remnants of the wound already knitting together, fresh skin gleaming over ruined muscle. It’s too fast. Too easy. He could sit here and chew at himself all night.
Ichigo stares down at him, shoulders heaving.
“Don’t—” He stops himself. Swallows hard. “You’re not expendable. Not any part of you. You’re not.”
The words come out both softer and harsher than he means them to, his hand shaking where it grips Zangetsu’s wrist.
And it hits him then that every second he’s this close, every breath he takes, every pulse of his reiatsu against Zangetsu’s, is making it harder for him.
“I know it hurts.” He presses his eyes shut, jaw tight, the air loud with the sound of two people breathing too close. “It’s alright. I won’t let you do this. Not to you, not to me.”
