Shikon no Tama

The Shikon no Tama (English:The Jewel of Four Souls) is the fictional magic jewel in Rumiko Takahashi's manga and anime series InuYasha. It contains four types of souls, Courage, Friendship, Wisdom and Love. The souls can make a person powerful. Before Midoriko sacrificed herself, she joined four souls within her heart, with the demonic one making it good and pure. This created the Shikon Jewel, where Midoriko and the demon are trapped within. The battle depends to any demon who kept the jewel. If the jewel is purified, Midoriko survives. If the demon binds the jewel, it becomes defiled. Naraku defiles the jewel, while collecting all pieces. Shako (Sango's grandfather) found the impured jewel from one of the demons. When Kikyo dies, the jewel survives and Naraku plans to retrieve it. Kagome Higurashi ends up travelling to the past while keeping the jewel. After Kagome destroys the raven, the jewel is shattered into pieces. Izumo is a philosopher half–demon who made the fake jewel with small power, by copying the real one. However, Inuyasha defeats him.
