Janis

Janis is an American exchange student who was made exclusively for the Nintendo DS game InuYasha: Secret of the Divine Jewel. She makes fast friends with Kagome and when coming to see her after school. One day she is attacked by a demon. At the end of the battle the mysterious Monk Sen instructs her to go into the well because thats where Kagome was. After meeting with Inuyasha and the gang she inadvertantly absorbs a jewel shard and soon after she develops special powers that were awakened by the jewel shard and is later given a spear to wield by the god of Mt. Habaki. Eventually she learns that she possesses these powers because she is the re-incarntation of a girl named Tsugumi, who was the human bride of the god of storms Datara. Being Datara's bride Tsugumi possessed some of his powers. Soon she learns Tsugumi's tragic tale where she was forced to kill her own husband and child on her wedding day because Datara had been possessed by a cursed mask and in order to thwart Tsugumi's attempts to stop him he held their infant daughter hostage. Tsugumi died after destroying her husband, a scenario very reminiscent of Kikyo and Inuyasha. Janis learns that defeating Datara and returning her powers is the only way to free the shard from her body thus stopping demons from hunting her. After she defeats Datara and frees him of the cursed demon mask, she is allowed to speak with Datara and Tsugumi where she learns that she is not Tsugumi's reincarnation but in fact the reincarnation of their infant half-god child. With the jewel shard out of her body and her powers gone Janis is unable to return to the feudal era, and returns to America shortly after the events of the game.
