The only injured people I thought was Super mega fairy boy (sorry Scar) and Megan 

Meaning thats 4 people liable to be kicked but if we factor in the checkup

3, meaning that since Tsukiko woke up and is only feeling lathargic she could just go back to her dorm room as she isn`t comatosed again and seems to have suffered no damage.

Vincent and Haas are just uninjured pack horses whom carry the injured, human crutch or otherwise so they can definitely go out.
