the day was new and the oh mighty lord of the western lands was pissed, while little Rin and and Jaken were off takeing care of his two headed pet dragon Ah-un though he would never admit that by all rights he should of let the dragon eat Jaken long ago just for entertainment)
well anyways why was sesshy so pissed? simple!
just as his wards took off Naraku showed up and insulted the one armed wonders girlishly good looks and the left just as fast as he came.
NO ONE insults the almighty mistress...er...master of the western lands so there was going to be hell to pay.
and so with as much dignity as he could muster his parting words to Jaken were "watch Rin until i return" the oh mighty fluff ball was off!
