He just stares in horror as Naoya moved, his eyes still fixated on the man, on the blood, the weapon, Naoya wiping blood off the weapon.

He's seen blood before, far too much of it. He's seen death before, more than a kirin ever should. He's caused death before but he's not thinking about that because he's already clinging on to calmness by a thread.

Naoya is speaking, telling him to breathe. He does, taking a deep breath and instantly regretting it as he is overpowered by the smell of blood.

He reached out, even if Naoya had just killed he is still someone he knows, someone safe. It takes a lot to move at all, his hand where it touches Naoya is burning hot.
