"Inuyasha" takes place in feudal Japan.  The story begins with Kikyou shot Inuyasha with her arrow and sealed him to a tree.  She then died and her body was burned along with the Shikon Jewel.  Then it shifted to current Japan.  Kagome and her family lived on ancient ground of an old well.  On her 15th birthday, she was pulled into the well by a centipede demon.  After she got out of the well, she was in feudal Japan.  She then saw a boy with dog ears pinned to a tree.  A group of people showed up and thought that she was a demon in disguise.  They captured her and brought her to the town priestess, Kaede.  Kaede noticed that Kagome resembled her late sister, Kikyou.  Later that night, the centipede demon attacked the village looking for Shikon Jewel.  Kagome ran back to the forest.  At that time, Inuyasha woke up because he smells the blood of the woman who killed him.  The demon attacked Kagome and jewel felt out of her stomach.  Kagome was desperate to stay alive, so she pulled the arrow out of Inuyasha, freeing him.  Inuyasha killed the centipede demon, then demanded the jewel for himself.  Kaede helped Kagome by placing a spell necklace around Inuyasha.  All Kagome had to say was "sit" and Inuyasha will fall to the ground.  Kaede said that Kagome is the reincarnation of her sister, Kikyou.  Now, it is her job to protect the jewel.  A crow demon later stole the jewel.  While fighting it, Kagome broke the jewel with her arrow.  The jewel fragments scattered everywhere.  Kaede said that Inuyasha and Kagome have to work together to collect the jewel, because Kagome is the only one who can see/sense the fragments.  

    This would be a somewhat of an easy task, except for the fact that every demons and some humans are also after the jewel.  The real excitement begins when Inuyasha's older brother, Sesshoumaru, showed up and wanted to kill Inuyasha.  Thing starts to really heat up when Kikyou was brought back to life by a demon.  Then Inuyasha and company found out about a demon named Naraku, who was responsible for Kikyou and Inuyasha's deaths 50 years ago.  Inuyasha's new goals are to collect the jewel and destroy Naraku.  Along the road, more people joined the group to destroy Naraku.  The first was a little fox demon named Shippou.  They then met up with a corrupt priest, Miroku.  Last, a demon exterminator, Sango, also joined their quest to find the jewel and kill Naraku.
