A 'trapped in a box' parody featuring Buriko.
I wanted a version with Buriko! Everyone thinks Buriko is a pain! Nine people have suddenly been thrown into an unknown, narrow, dark space!! It's so cramped that nine people can barely fit, so you can't move at all! Can you get out?? You'll have to clear various trials.
