Your My Contractor?! || ＫＮＹ

A different time where Kyojuro Renjoku discovers a mysterious cavern with an ominous feeling within it. As if it was almost like a dark and frightening myth.

And as they say, curiosity kills the cat, he went to investigate. Oh how foolish he was. He was ignorant to feign ignorance to his fear and succumb to curiosity that may get him killed. Today.

He hadn't even written any will yet. And if he was gone, who would take care of his dear younger brother? His father? Or be the flame hashira? Or what if-

Wait a minute...what were those just now?! Has he gone crazy?! He hadn't even stepped that far into the cave and yet why is he so sure that he would die as of today?! He knows himself. He knows he wouldn't just give up the moment he encounters an obstacle in life. This was just one of those obstacles on a much higher difficulty.

So the question was, what was making him think of such purid thoughts? And what in the world is making him like this? He has a bad feeling about his....And worse?

His instincts are going haywire to let him know to get out of that cavern as quickly as possible. Because he has a feeling this isn't a demons doing.

But one thing our little protagonist had overlooked was, whatever was in that cave, his decisions will decide the outcomes for everyone's future.
