Note: I had some comments about how the meeting between Kagome and Sesshomaru was going to go, given his not-so-friendly canon personality, so I decided to give you some omake that I wrote which shows how the timeline differs. These aren't entirely serious, but the plot is relevant to the overall story. Hope you enjoy!
Journey to the Future – Omake 1, or "What Happened to Naraku?"
Sesshomaru sighed irritably as he made his way across the Western lands. He had heard a disturbing rumor that his younger brother had gotten himself killed at the hands of his miko lover. There were so many things wrong with this situation that Sesshomaru didn't know where to start. He would be extremely put-out if Inuyasha had perished… he was the one who would end that wretched hanyou's life, not some human woman. If he truly was dead, Sesshomaru decided that he would use Tenseiga to bring him back to life just so he could kill him again. That his father had sired a hanyou, forcing Sesshomaru to be related to such a disgrace, was bad enough; if Inuyasha was going to insist upon living to adulthood, he should at least had the decency to keep himself alive until Sesshomaru decided to end his miserable little existence.
Jaken trotted along behind him, going on about some kind of nonsense. The daiyoukai rolled annoyed golden eyes. He was beginning to regret bringing the little toad along. Still, he did at least provide some entertainment. Sesshomaru subtly (and deliberately) kicked a rock back at the little youkai's head, earning himself an indignant squawk. As no one was around to see, he allowed an amused smirk to cross his lips.
Sesshomaru's expression smoothed over and he stopped in his tracks as an unpleasant scent teased his nose. It was coming closer to him, and since he always had been a curious demon, so he waited for the source of the odor to show itself. Jaken ran into the back of his leg and Sesshomaru kicked him away irritably.
From the trees emerged a figure cloaked in the skin of a white baboon. He smelled foul, causing Sesshomaru's nose to wrinkle in disgust. "Greetings, Sesshomaru-sama," the figure said in an oily voice, bowing its head. "I am called Naraku."
"Hn. And what do you desire of this Sesshomaru?"
"I desire power, Sesshomaru-sama, don't we all?" The hanyou (a fact Sesshomaru could discern immediately, despite the pest's noxious scent) made a grand, sweeping gesture.
Sesshomaru's cheek twitched in irritation. He didn't have time to listen to every delusional youkai chat his ear off. "How very nice for you," he sighed, turning to the left and continuing through the trees.
"I have done you a favor, Sesshomaru-sama," the foul-smelling hanyou said smugly, raising his voice slightly for emphasis.
This one certainly liked to be dramatic. With a tiny sigh, wondering why he didn't just end the creature's life and be done with it, Sesshomaru turned back toward the baboon-cloaked figure.
"And what is it you believe you have done for this Sesshomaru?" he asked imperiously.
"Why, I have taken care of that nuisance you were saddled with as a relative." Although his face was hidden, the hanyou radiated smug pride. When Sesshomaru remained silent, he continued speaking, describing in detail how he masqueraded as Inuyasha to heavily wound Kikyo and then tricked Inuyasha into attacking the shrine and stealing the Shikon jewel, leading Kikyo to seal him to a tree.
"The bitch miko had the jewel burned with her corpse and it has left this world. But with your power combined with mine, we could—urk!"
Sesshomaru flexed his fingers from where they were located inside the abdomen of the oily hanyou. Naraku's flesh sizzled as Sesshomaru's poison began to spread throughout his body.
"W-why…?" The dark hanyou asked in confusion. "I thought you would… be… pleased…"
"My half-brother is mine to spare or kill as I please," Sesshomaru growled. Before Naraku could respond, Sesshomaru reached up with his other hand and neatly decapitated the hanyou.
His body burst apart into a hundred insect youkai, each of which tried to flee away from the angry daiyoukai.
Sesshomaru cracked his knuckles again to get his poison flowing and flicked blades of toxic youki at the fleeing creatures. In a matter of seconds, the area around him was littered with the dismembered corpses of a hundred weak youkai.
"Disgusting hanyou," Sesshomaru murmured. Underneath the tattered baboon cloak was the twisted, charred figure of a human. It gasped noisily and was trying to crawl away from the inu-youkai.
"No… no…" it moaned piteously.
Sesshomaru crinkled his nose at the sour odor of burned flesh and he brought down the heel of his boot firmly, crushing the wretched creature's skull and ending its life. He had heard of such things, humans making pacts with hundreds of lesser youkai for power, but this was the first time he had witnessed it. Yet another reason to despise humans.
"Sesshomaru-sama!" squawked Jaken as he ran clumsily back to his master's side.
The daiyoukai turned and planted his boot in his retainer's face. "Jaken, cease your talking," he said irritably.
With an annoyed sigh, Sesshomaru continued on toward the small village where Inuyasha had last been residing. If Inuyasha was truly just sealed, Sesshomaru would just wait until he was unsealed to kill him and if the hanyou was dead, than Sesshomaru would finally get to test out the unsatisfying sword that was left to him by his father.
