Get the original Japanese version of InuYasha. This is the same as the VIZ Comics version, but in Japanese! Reading from right to left, this is the first volume of Rumiko Takahashi tale.
The story begins in Tokyo, Japan with a junior high-school girl named Kagome Higurashi, who, on her way to school, heads to the covered well on the family property (which happens to be a Shinto shrine). She does this to retrieve her cat, Buyo, from the well, since her brother was afraid to go inside. When she approaches the well a centipede demon (dubbed "Mistress Centipede") bursts from the well and grabs her. The demon claims that Kagome possesses the Jewel of Four Souls (四魂の玉 Shikon no Tama), and attempts to seize it. When she drives the demon off by an unknown and mysterious power, the very confused Kagome emerges in the Sengoku period of Japan.
