InuYasha , full title InuYasha, A Feudal Fairy Tale , is a popular Japanese shōnen adventure romantic comedy manga created by Rumiko Takahashi. The story tells of the adventures of Kagome Higurashi, who can travel back in time through a mysterious well, and the half-demon, InuYasha, along with their companions Miroku (a lecherous monk who accompanies Inuyasha to defeat the demon lord Naraku, to rid himself of the black hole in his hand), Sango (a demon slayer wanting revenge on Naraku for the death of her brother and village) and Shippo (an orphan fox demon). The whole group travels together, seeking to kill Naraku as revenge and gather all the shards of the sacred jewel (Shikon no Tama, which was broken accidentally by Kagome) to keep them out of the hands of demons. It was adapted into an 167 episode anime series produced by Sunrise which first aired on Nippon TV in Japan from 16 October 2000 to 13 September 2004. The television run of the anime ceased without a conclusion to the story. The manga is still being released in Japan as of today.

The series is named after the main character, InuYasha. The name "InuYasha" literally means "dog demon". Inu is a Japanese word meaning "dog". Yasha is a Buddhism-related word meaning "demon or demon warrior".
