Hyoi and Ryoi, two brothers with the power to take the form of cats, must unravel the mystery of a creeping, tenticled, demon plauge before it consumes them and their classmates. Ultimately, they must confront their old Dark Cat master Jukokubo, though whether they can put an end to the evil he has released remains a mystery.
Unfortunately the movie Dark Cat is not yet available on HBO Max.
