Kuzumi Hiroshi moves to the town of Joga with his father and his handicapped sister. The town's stories of man-like wolves seem like small town lore. But when people start to go missing, it's not out of the realm of possibility.

Due to his father's job, 15-year-old Hiroshi Kuzumi and his family move to the mountain town of Jouga. While some teenagers might have to worry about fitting in or feel out of place in a new environment, Hiroshi is welcomed enthusiastically at school by most of his new classmates. In fact, it seems like they just can't get enough of him, and he makes two friends rather quickly: the clingy and overly-affectionate Isuzu Tsumuhana, who is also his neighbor; and Kaname Asagiri, who also recently moved to Jouga. All in all, Hiroshi's new life seems to be quite normal-until people start disappearing. Hiroshi is told that the missing townsfolk have simply moved away or suddenly transferred, but he can't shake the feeling that something is wrong. Meanwhile, in the dead of night under a red moon, masked individuals led by a girl with a scythe stalk their prey in the darkened streets of Jouga. Who are they, and are any of the residents safe from their wrath?—MAL Rewrite

From the moment Hiroshi and family arrive in Joga, he senses something odd about the isolated village It's not that the people are cold and aloof. Except for his beautiful class president, Nemuru, most welcome him quite warmly. But some also simply disappear. Students transfer out of his school without any notice, and Hiroshi's next door neighbor Isuzu, who seems quite infatuated with him, warns him to stay away from the old part of town. The upcoming Haasaku Festival, which celebrates the town's unique oranges, seems to be generating an unusual level of concern, and groups of masked people roam the streets by night, hunting something. Could the legends of man-sized wolves roaming the mountains surrounding Joga be real? Who is the girl with the scythe? What is the real purpose of the festival? And how does this all revolve around something called a Temptation? Hiroshi and his new circle of friends have little time to solve these riddles before the answers will become far more dangerous and personal than he could ever imagine. Beneath the mask of society and the skin of humanity, something ancient awaits in Okamikakushi MASQUE OF THE WOLF.—Sentai Filmworks
