Inuyasha follows the adventures of Kagome Higurashi, a teenage girl who is transported from modern-day Tokyo to the Sengoku period of Japan after falling into a mysterious well in her family's shrine. There, she encounters a half-demon named Inuyasha, who is pinned to a tree by an enchanted arrow shot by the priestess Kikyo after a misunderstanding. Together, Kagome and Inuyasha embark on a quest to retrieve the scattered pieces of the powerful Shikon Jewel, which grants immense power to whoever possesses it. Along the way, they are joined by various companions, including the monk Miroku, the demon slayer Sango, and the fox demon Shippo.
