Inuyasha

is a Japanese manga series written and illustrated by Rumiko Takahashi. It was serialized in Shogakukan's manga magazine Weekly Shōnen Sunday from November 1996 to June 2008, with its chapters collected in 56 volumes. The series follows Kagome Higurashi, a fifteen-year-old middle school girl from modern-day Tokyo who is transported to the Sengoku period after falling into a well in her family shrine, where she meets the half-dog demon, half-human Inuyasha. After the sacred Shikon Jewel re-emerges from deep inside Kagome's body, she inadvertently shatters it into dozens of fragments that scatter across Japan. Inuyasha and Kagome set out to recover the Jewel's fragments, and through their quest, they are joined by the lecherous monk Miroku, the demon slayer Sango, and the fox demon Shippō. Together, they journey to restore the Shikon Jewel before it falls into the hands of the evil half-demon Naraku.

In contrast to the typically comedic nature of much of Takahashi's previous works, Inuyasha explores darker and more serious subject matter, using the setting of the Sengoku period to display violent content while still retaining comedic elements. The manga was adapted into two anime television series by Sunrise. The first series ran for 167 episodes on Yomiuri TV, Nippon Television, and their affiliates from October 2000 to September 2004. The second series, Inuyasha: The Final Act, is a direct sequel that adapts the remainder of the manga and ran for 26 episodes from October 2009 to March 2010. Four feature films and an original video animation (OVA) have also been released. Other merchandise includes video games and a light novel. An anime-original sequel spin-off television series, titled Yashahime: Princess Half-Demon, aired for two seasons from October 2020 to March 2022.
