While Harumi and her class are on a school trip to an amusement park, they are attacked by a Squid Demon named Walter Geso. Despite taking Yukiko hostage as well, Enma manages to free all the hostages and defeat the demon, albeit destroying the park in the process. Afterward, Yukiko and the others explain to Harumi how they were summoned by the Great King Enma, Enma's uncle, to travel to the human realm to stop escaping demons. Their first case involves fighting demons named Snakejar and Shock Willow. After the flashback, Harumi reveals that he teacher, Ms. Chiko, had been acting weird recently, and upon investigating her, they find a strange mark on her leg.
Tokyo in the 1970s. Evil spirits are threatening the human world and the only ones who can stop them are a group known as the Spirit Patrol. Sent from the underworld the team consists of the hot-headed Enma, the stuck-up Yukiko, the half-water sprite Kapael and Chapeau-jii — the old man spirit in the form of a hat, who guides the group. This may not bode well... though.
