The room had a way out other than the hole they'd entered from. It was hidden behind the paper screen of moving reeds. There, though hard to find, was a gap on the wall - and it led into a hallway.

The kids wouldn't have noticed immediately, not in such deep darkness, but this corridor didn't look like it belonged to the school. There were no classrooms, and if there were doors they were old fashioned Japanese sliding ones. There were windows looking out into the courtyard, which would imply it faced the outside, but none of the kids would remember seeing this side of the building...

You will reach your goal in two turns (each turn consisting of a tag by each of the players.)
