Inuyasha

In 1496 Japan, humans and demons (yōkai) battle over the Shikon Jewel (Shikon no Tama; lit. 'The Jewel of Four Souls'), which is said to grant any wish. Kikyo, the priestess who keeps the Jewel, is in love with the half-demon Inuyasha. However, they fall into a deceitful trap and betray each other. Inuyasha steals the Shikon Jewel, but the dying Kikyo pins Inuyasha to a tree with a sacred arrow. Per Kikyo's will, her body is cremated along with the Shikon Jewel, which disappeared from the era.

Tried to make it as close to the anime as possible, but this is your world, your characters, play it as you wish and have fun ^.^
