dislocated thigh

Even a hit from the side of a notebook would daze someone if it was to the back of the head. That was not a spot you could afford to let someone attack you. She was lucky that she had not lost consciousness…no, that she had not been killed.
(Are you kidding me!? What happened!?)
“!!”
“Whoa now.”
Bluish-white sparks crackled out.
She forcibly jumped forward and planted her feet on the wall of the narrow emergency passageway, but her eyes were still shaky and refusing to focus.
“You can use your power on your own nerves? Is there anything you can’t do?”
(I…)
An unpleasant sound caught up to her, but she sensed it more through her bones than from her ears.
(I dislocated…my thigh!!)

This was a trick she had learned from the Queen of Tokiwadai Middle School’s right-hand girl who handled most of the physical work since the Queen herself was so hopelessly unathletic, but just being able to control electricity was not enough to pull it off. Mikoto’s power was strong enough that she had to be very careful to avoid frying her own nerves or breaking her own bones.
She had no choice but to bite down on a handkerchief.
She suppressed the pain and used both hands as if shoving in a large hook.
She jammed the dislocated hip joint back into place!!
