Disclaimer: In no way nor form is Natsume Yuujinchou my own. Neither is the original idea for this fanfiction. That comes from the fiction A Youkai's Blessing by CitrusShinigami.
Warning: Includes non-consensual acts and yaoi. Don't like, don't read. I won't go into depth on any arc in the series, so if you know all the major players and don't really care about any smaller ones I may include, read onward.
Prologue:
The night was silent, and peaceful. A mysterious calm set upon Natsume, something that doesn't happen often. Shaking off the ominous feeling of experiencing the calm before the storm, he closed his window. The air wasn't rigidly cold, but he didn't want to wake up with a sore throat, or more likely, an infestation.
Slightly grimacing at the thought, he quickly turned off his room's lights and got into his futon. Situating himself, he fell into a restful state, knowing Nyanko-sensei was there by his side to keep him from harm, should he need his protection. Perhaps more in it for the protection of the Book of Friends, rather than the protection of the human that came along with it, it nonetheless reassured Natsume. At the very least, he wouldn't have to worry about the youkai whose names he still had yet to return upon his death.
Reaching for the familiar cat shaped youkai, he ran his hand through the creature's soft fur. Normally, the action would be much to its distaste and it would recoil from his touch, but as it was currently too far drunk to care, it simply purred and nuzzled into the comfort. Eyes softening at the oddly cat-like behavior, Natsume began to drift to sleep.
Just as Natsume's conscious truly and wholly gave way to rest, an ayakashi appeared at his doorstep. It seemed to hesitate on entering, maybe unable to or thinking better of its actions, and instead moved to drift under Natsume's window. Its body seemed to suddenly relax at reaching its final destination, and it closed its eyes.
Softly, it chanted words in a language far too old for any human to understand, yet somehow communicated the message perfectly, if any were to hear it.
A blessing turned curse to be released, need only one more vassal to disappear. With the sacrifice of this one, it shall be concluded, and with its end, its effect with it. I release you unto the youth, Natsume Takashi.
Upon the name being said, vibrant red, black, and white rose petals seemed to drift from its body, slowly making its way towards the closed window, floating upon a nonexistent wind. The petals, being of a spiritual manner, of course simply bypassed the window and alighted onto the sleeping figure of the teenage boy. Upon landing, the petals melted into light blue and silver, any traces of their previous colors disappearing. Seeming to gently yet surely merge with his skin, a small flash of soft blue light shone, casting the room in a subtle glow.
As the remnants of the transaction faded, so did the youkai. Seeming to be caught in a sudden gust of wind, though the night remained completely still, it disintegrated from the feet up. When all that remained was its upper torso and head, it briefly thought to the young man, to the boy it just cast its misery onto, a solemn good luck. Then, it vanished and was no more, with none the wiser for its presence, or lack thereof.
AN: I may or may not be continuing this, really just depends on what people would prefer to happen. Expect a chapter or two by the end of this weekend. If anyone has any ideas for a coupling or such, I'm open to suggestion.
