Kagome Higurashi is a 15-year-old ordinary girl in the third grade of junior high school. One day, she accidentally came to the Warring States Period 500 years ago through the dry well of the shrine at home. At that time, war smoke was everywhere, monsters were rampant, and the world was in ruins. Kagome met the sealed half-demon Inuyasha at the sacred tree. 50 years ago, Inuyasha, who wanted to become a real monster, met Kikyo, a witch with powerful spiritual power, in order to obtain the Four Souls Jade. After a period of getting along, the two developed feelings. Inuyasha therefore hoped to become a human, and Kikyo also planned to return to the life of an ordinary person after purifying the Four Souls Jade. However, the thief Onigumo, who had evil thoughts about Kikyo, gave his soul and body to the monster, and then reincarnated into the evil half-demon Naraku. Under his instigation, Inuyasha was sealed on the sacred tree by Kikyo, and the seriously injured Kikyo died in sadness and despair. Kagome, who was reincarnated by Kikyo, rescued Inuyasha, but accidentally shot the Four Souls Jade into pieces. In order to retrieve the fragments, she, Inuyasha, and the companions she met later: Qibao, Miroku, and Sango embarked on a journey full of hardships and dangers...
