Also known as: 全裸登校
A subset of the Zenra fetish revolving around attending school while in a state of undress, treating it as a normal, everyday activity. Typically, these impractical "uniforms" or nudity are considered to be the students' school uniforms. Other settings might instead have a "nudity day", a special school day where students and teachers must attend the School naked.
This also covers the commute to school these naked students take, sometimes within the presence of other people who are wearing normal clothes. In that case, Exhibitionism may also apply.
