After Making a fool of yourself in class, you're relieved to hear sensei say lessons are done for the day, but you're confused when the day is only half way done. The girls, concerned, come to question you to make sure you're okay, but you just lie and say you couldn't really sleep last night and you feel out of it using it as the reason for why you forgot to put on a bra, this seems to convince them well enough, but your heart drops when you hear someone say, "Hero Training". You are absolutely not combat ready for this and you're already panicking, wondering what's going to happen.
Going to the Locker room with the girls, you keep quiet and avoid conversation, with one word responses. Going to your locker you're relieved your uniform is already here, and you strip down and begin to squeeze into it, avoiding looking down at your body, after putting the costume on, it supports your breasts as it holds them up, as much of a tight squeeze it is on your chest.
Going to the gym, you see it's an obstacle course, and when it's your turn you do... less then average. Getting burned by nearly every fireball, sliced by every axe, or crushed by every pillar. By the point you reach the end you have the worse time, as your costume is in pieces and your sweaty flesh is popping out of every tear and your breasts almost tear through the leather of your costume with each heavy breath.
