This may be a long shot, but awhile back I read a manga that, if I remember correctly, was about a teacher/sensei who was on some sort of trip with his class of girls. They were on a subway platform when there was an earthquake and they were trapped underground. Things proceeded about how you'd expect from there. I've tried searching all of those keywords, but have had no luck. Thanks in advance!
