Yūma had been braced for a lot of things. Some final grand show of force, suicidal last attack, ranting, raving, some grand speech or the like. He had not, however, been ready for the spirit to seem to come to his senses, collapse to his knees, and begin muttering about his failures and inability to escape whatever cycle he had been trapped in. Assuming, after his fellows had died alongside him, he has been stuck in this loop of murder, slaughter, defeat, realization, only to be condemned to it again, Yūma figured that Hell certainly was a thing. This samurai had been living a form of it, and if the agent knew of any way to put the spirit out of his misery, he would have done so without hesitation. Part of him felt a pang of guilt for enjoying the brawl with the spirit as much as he did, but it was gone as soon as it appeared. So far no one seemed keen on answering the question posed about everyone being long dead, which Yūma would at least confirm for the poor soul.
"Unfortunately, yes the village and its people are long since gone."
Listening as the offer to decapitate the samurai with his own sword, in an attempt to carry out the full ritual suicide, was another dark note on many that had come to the fore of this. He ran through his far more limited knowledge of the supernatural, of folklore and the like, thinking out loud as he did. Yūma was at his best fighting and brawling, but now was putting the other part of the whole job to work. Contain or eliminate the anomaly, which meant considering all the options available to them.
"Never been much of one for memorizing folklore, but wasn't there something about the spirits of the dead being unable to move on with unfinished business left? Resolving that might help too, least worth considering at any rate."
