Kagome's story begins in modern day Tokyo, Japan. On Kagome's 15th birthday, she is on her way to school when she notices her cat, Buyo, has run off toward her family's Shinto shrine. She goes looking for Buyo as she approaches a well behind her family's house. Suddenly, a centipede demon emerges from the well and drags Kagome into the well with her. Kagome awakens in the well and climbs out only to find that she is no longer in her family's backyard, but in the Feudal Era of Japan.
