No, so this calls for some attempted investigation...

Having waited what should be more than enough time, Erika presses her well-practiced hands together into the correct ninjitsu pose, and channels her ki into her legs and torso, willing them to start spinning again.

But to her surprise, and mild concern, nothing happens.

That's strange... She thinks to herself, and tries to focus on her body, to understand what's wrong.

To her great confusion, she realizes that she can't feel anything below her armpits at all.

Now, most trainee ninjas, and many rookie ninjas, would have little insight or wisdom to choose the right thing to do here. The most common course of action would be to exercise patience, and wait to see if their sensations, and ability to send ki down into their bodies returns soon.

But a suspicion raises its flag in Erika's mind. What if something is more wrong than she realizes? No, surely not... Right? But it's worth checking, if at all possible.

So, gathering what ki she can in her upper body, she performs a ki-enhanced meditation. She kills as much external sensation and noise as she can, and focuses all her attention on how she feels inside.

...And she manages to successfully push gently past some kind of powerful barrier that is blocking all sensations from the parts of her body that are under the ground.

It's not much - only a very partial penetration of the barrier - but it's enough for her to feel some STRONG sexual arousal bubbling up inside her core. Now that she's penetrated this part of the barrier, it stays broken, and she can feel this strong, hot, burning sexual delight down below. It fills her brain with pleasure, and threatens to break her focus.

A lesser trainee might panic. In fact, Erika is close to bottling it and panicking herself. Perhaps on a different day, or in a different moment, or with a different roll of some hypothetical metaphysical dice, she would. But today, in this moment, she manages to keep her cool, and urgently do the only thing she can right now - call for help.

Collecting her remaining ki and sending it to her vocal cords, Erika performs a thunder cry, amplifying the volume of her voice around 2000%.

"SENSEI! COME BACK! SOMETHING'S WRONG! HELP!"

Ishita left over a minute ago. Will she be too far away to hear that? Will anyone else hear it? Will they help her escape? Only time (and another die roll) will tell...
