Kaiba was finalizing an email to his R&D lead when the door opened. He looks up after a moment, appraising the small man who had just entered his office. A mouse, this one. Aside from being diminutive, he seemed not to take much space socially either.

The appraisal is dire...at least for a few moments.

Then it hits like a truck at impact speed, and Kaiba reels back despite himself. This mouse of a man had a scent that seemed to latch into Seto Kaiba's vampire instincts and rip them past the day-to-day mask he wears. Unbidden, his fangs push past his lower lip and his jaw clenches so hard that it nearly makes him wince from the pain of it.

But the worst of it...it wasn't the jaw. It wasn't the fangs he tried to hide by parting his lips.

It's the sound of blood rushing in a waterfall by his ears, pulsing just below the surface of the human's skin. His veins sing a song Kaiba has never accepted the invitation to dance to.

His throat works involuntarily, aching and parched and he wants to sink his teeth into the man, to feel his skin pop and give beneath the prick of Kaiba's fangs.

All of this happens in the span of a moment, but all Yuugi will be able to see is the look on his new boss's face.

It's a look of alarm, mixed with the involuntary swallowing motions that Kaiba couldn't stop. He looks...unwell, to say the least.

"Get...out."
