Sho wasn't entirely sure that Ume's idea was going to work - after all, night-vision wasn't something that one just developed. Though it was indeed true that people's eyes adjusted to darkness when given enough time, that only worked when one had even a fragment of light to work with - whether that came from rays of moonlight or a flickering candle, even basic night-vision required something. Anything.
Well, he supposed he would trust in Ume, at least for now - this wasn't her first rodeo, surely she wouldn't let her own bravado get her killed.
Right?
Either way, the two continued their travels through the cave, each step bringing them closer to their targets. From what Sho was able to tell, there was about ten of them, each one draped in full-body robes and ornate finery that bore the symbols of their religion. The iconography of blood and bone, one might almost mistake them for Shitai were it not for Ume's clear unfamiliarity with their presence.
As Ume reached out for him, Sho paused, listening as instructed. They were singing indeed, but it wasn't any words that he understood. It wasn't like they were throat-singing like some of the people in the mountains did either, no they were clearly speaking words just not words that he knew. Perhaps some sort of ancient language? It certainly had that sort of import to it, the archaic reverence that such old words bore. Though Sho could not tell what they meant literally, even he was able to tell just how ominous they were - they could mean nothing good.
Speaking of meaning nothing good, Sho's attention had been distracted by the singing for long enough for him to almost seemingly forget about the incoming patrol. One of the ten had come wandering off, and had apparently had the misfortune to stumble upon them. Before Sho was even able to act, Ume had already shot forwards, pouncing on the opponent and sending them down to the ground with a simple bite into the neck. It was powerfully feral to watch, like an animal taking down their prey rather than a ninja taking out a target. He almost found it hard to look away, but look away he did as he instead moved over the fallen body of the opponent, ignoring the way the man's heartbeat seemed to ebb away and instead focusing solely on the cave in front of him.
"Alright, so, " Sho began, letting Ume follow behind him as they walked. In order to avoid them being detected he kept his voice down as he spoke, though there was a certain urgency in it. Fortunately, the continuation of the singing without missing a beat let Sho know that nobody had been able to tell anything. Or, perhaps and significantly more worryingly, they simply had not cared.
", there's about nine more of the guys down here. We're walking in on what appears to be another one of their prayer circles, so expect to be surrounded by blood and bone. More importantly..." Sho paused for a second as a violently unpleasant sensation hit him like a slap across the face, a sudden burst of wind from further within the cave carrying with it a vile smell.
Sho had spent years working at the hospital, he had been around people as they died, he was no stranger to foulness. Whether it be the astringent smell of bleach, the noxious smell of someone's voided bowels, or simply the lingering stench of death, he had smelled it all. Or so he had thought until this new smell hit him. It was like rot and putrescence manifested into a single smell, like a living plague communicated solely through scent.
It was said that deep within the Land of Forests there was a plant that had evolved to smell like rotting flesh to lure in carnivorous insects to devour and was so powerful one could smell it for miles around. Even so, compared to this, that sounded almost like the finest perfume. He couldn't even understand how something could be made to smell this bad, let alone know what was causing it.
"... I'm really hoping that whatever they think they're summoning is just more of their insane ramblings." Sho murmured, having to take a moment not to physically retch.
