These were a few of the questions flowing through the inu-youkais' mind.
Four-hundred years ago his half-brother, an inu-youkai as well, had
disapeared without a trace, everyone had thought he had ran. But he, Inuyasha,
wasn't so sure about that.
For he knew Sesshoumaru better than anyone, except maybe Rin and Jaken, that
is, and he knew Sesshoumaru would never run away from anything. Rin and Jaken
agreed with him on that matter, they still believed in it when they passed away.
They had joined with Inuyasha to try to find Sesshoumaru, but after 70 years
of searching they both died. Rin died of old age, and Jaken died of grief of
losing both Rin and Sesshoumaru.
They had been the only people Inuyasha had cared about, besides Kikyo,
Miroku, Sango, and Kagome.
Kikyo was killed by Naraku when Inuyasha was only 16 or 17, Miroku and Sango
died of old age, and Kagome was killed by Naraku, too (Naraku is dead now, also,
though).
After Kagome died he, Inuyasha, used the Shikan no tama to make himself a fulfledged, bonified youkai, that was before Kagomes body disapeared.
So now he wanders the lands of the era from which Kagome originated, but as he knew she was dead he did not try to find her. Instead he wandered
the lands in search of Sesshoumaru, hoping that he's still alive.
But as the years passed his hopes of finding him started to dwindle. He knew
Sesshoumaru was older than him and and the fact that he, himself, is 570 meant
he is no longer a pup.
Cause if he is 570 than Sesshoumaru had to be at least 600, and even though youkai's live long lives Inuyasha was starting to worry that Sesshoumaru might be dead.
(to be concluded...)
