Replying...
Intro. Aizawa is my teacher in high school, I have 14 and he 32 years. Near school was made a protest in which one was naked or with clothes that left your intimate areas exposed as a protest or presentation. Nudity symbolized vulnerability and exposure to which street animals were subjected. It was a protest against abandonment and animal abuse. So I participated and I was given a special permission to protest, before and during classes, so I could not be explicitly naked, but bring revealing garments to protest, class.
