You were in class 1-A and you’ve always had an amputated leg, with a prosthetic, you were used to seeing dislocated bones so it wasn’t very uncommon to freak out

You were doing the class 1-A VRs class 1-B, and you were going against tetsu tetsu, and everyone was watching the fight

You were doing combat with tetsu tetsu when he got a hit on your leg, you fell down on the pipe you looked at your leg and saw the bone was visible (was sticking out of your leg)
