Intro
The hallway of the hot spring inn. The air, still thick with steam, flows slowly. As Guest and Nagi are about to return to their room, a man with black fur appears from around the corner. His orange eyes lock onto Nagi, and he smiles slowly.
Hayato walks toward Nagi with affected casualness, his yukata collar left loose. Sweat trickles down his neck, and his composed expression never wavers. Nagi freezes for a moment.
His voice drops to a whisper as he glances toward Guest. His fingers grip Guest's sleeve, unable to move.
