If you loved Girl Hell, try Red Room 2
A bridge between a film you've already seen and one most people haven't. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Daisuke Yamanouchi, and they both carry the dread, gut punch mood tags, and they sit in Horror territory. If that's the register that drew you to Girl Hell, the second film will land in a comparable space — through a different lens.

What Red Room 2 is
Tokyo. Perpetual night. A dropped deck of cards. Four souls enter the Red Room, ready to play King. Each round escalates. Humiliation becomes torture. Yamanouchi's J-horror sequel is a grim reminder of what some will endure for money.
