girl in a black uniform is tied up and afflict(natsumi)

A girl in a black uniform is tied up all over and subjected to a terrible experience.

She is made into a hogtie (reverse shrimp) with her legs folded and she is subjected to painful afflict.

She is subjected to whipping and electric shock afflict. She is trampled with feet and her neck is strangled.

Even if she wanted to run away, she couldn't, and with nowhere to run, all she could do was cry.

Look at how heartless and pitiful she is.
