The yakuza princess was somewhat concerned when someone tripped, right into the teacher at that, but stopped looking when it was clear that she was fine. Not that she could have done anything if the trip-er wasn't; first aid wasn't amongst her skills and nobody wanted her assistance. They'd probably think she was working on killing them, or making their injury worse, or otherwise ruining their chances of being in good health. Then, if anything went wrong, she would be blamed.

No, it was good that they were okay. Less chance to be accused of not caring, or of caring in the wrong way.

Junko got a one-word reply: "Aikido." That was all that Kotone said before slumping into her seat, gazing out the window, and tuning out the usual pre-class announcements, thus complely missing that they were picking a class representative. Not that it mattered, she didn't care who it was, anyway.
