Janis

is an American exchange student who was made exclusively for the Nintendo DS game InuYasha: Secret of the Divine Jewel. She is also the reincarnation of the daughter of the god Datara. When Kagome Higurashi was absent from school, Janis went to Higurashi shrine to visit Kagome where she was attacked by a yōkai who emerged from the Bone Eater's Well and rescued by the mysterious Monk Sen. Later, Janis followed his advice to go to the feudal era through the well and looked for Kagome. After passing through, she met Kagome and her friends. Once she touched a shard of the Sacred Jewel, it blended in with her body and awakened her Kamui powers. She agreed to accompany them on their journey until she was able to remove the Jewel Shard from her body.

History
She made fast friends with Kagome and when coming to see her after school. One day she was attacked by a demon. At the end of the battle the mysterious Monk Sen instructed her to go into the well because that's where Kagome was, and as her fate. After meeting Inuyasha and the gang she inadvertently absorbed a jewel shard and soon after she developed special powers that were awakened by the jewel shard and was later given a spear to wield by the God of Habaki. Eventually she learns that she possesses the Kamuitama because she is the reincarnation 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 the 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 Kikyō and Inuyasha. Janis learned that defeating Datara and returning her powers was the only way to free the shard from her body thus stopping demons from hunting her. After she defeated Datara and freed him of the cursed demon mask, she wa 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 was unable to return to the feudal era, and returned to America shortly after the events.

Physical description
Janis wears an academy uniform with a blue top with a red tie in a gold trim, white stockings and penny-loafers similar to Kagome's, and a grey skirt. She has long, curly blonde hair held back by a red clip, white pearl earrings, pale skin, and blue eyes.

Personality
At the beginning of the game, Janis is a little cold and standoffish to other people such as Yuka, Ayumi, and Eri. Her only friend was Kagome, but still retains a slightly friendly demeanor. She also appears to have a caring side, such as when Kagome didn't show up for three days (she was in the Feudal Era), she decided to go visit her. She's also seems to be adventurous, when she mentions that the Feudal Era seems to be dangerous, but "kind of fun" as well.
