The Demon Behind (S04E05)

Jackie and the crew discover the next Oni mask along with a detailed archive of demons. Excited, Jade suggests they use the talisman on the mask to interrogate it. Unexpectedly, the mask leaps onto Tohru, then jumps to others, eventually making its way to Finn's car. Tarakudo urges everyone to track it down as it escapes. Finn heads to his car, unknowingly sitting on the mask. In a twist, they manage to catch Tohru, but the mask compels him to wear it. In the end, Jackie swoops in to save the day once more.
