There were five doors along the sides of the hall. Oh, and more Undead. Only this time there was one jawless woman standing weeping in the hallway while two other ambulatory corpses, male, made their way towards Kai, slowly and trudgingly, apparently on patrol.
They resembled filthy Zombies in ashigaru armor and carrying spears, their bodies absolutely covered in dirt, weeds, and other detritus. The dirt and weeds seemed to be fused with their very bodies, even.
Naturally, being that he was incorporeal, the slow moving things didn't notice him.
Upstairs, Kai could hear heavy footsteps - either a sumo wrestler in iron boots, or some manner of Oni. Probably the latter.
