Shin Megami Tensei IV -Prayers-

Ys is a prodigy who is rumored to be the next leader of the Samurai after Hope.

He is first seen in Mikado Castle's Samurai Station, filling in for Hope due to an urgent meeting. Ys praises Jonathan for quelling the Shim O'Key Tezawer village fire and slaying the Pele that caused it. He later joins Jonathan, Walter, Isabeau, Navarre and Asuma after catching them sneaking out at night to attend a Sabbath. Together they discover that the Black Samurai is behind these Sabbaths and is turning people into demons with books. After Asuma slays a human who has turned into a demon, Ys decides to stay behind and investigate. He orders his fellow Samurai to return to the Dormitories. While investigating, he intentionally opens one of the Black Samurai's books to become a demon.
