A longer, somewhat slower, linear story with changing perspectives to tell an intriguing story

The vast majority of the images used for the first arc of this story were drawn by "chicken (nijie)", and these illustrations indeed served as the inspiration for this story.

You are about to read a story set in a unique Japanese academy.

Rest assured, all the students in this academy are aged 18 and older.

Things may seem confusing at first, but that is largely intentional. Hopefully, by the end, the vast majority of your questions will have been answered.

THE RECOMMENDED WAY TO READ THE STORY IS BY IGNORING THE BONUS CHAPTERS, AND TO SKIP CHAPTERS WHERE ABLE. They contain extra smut, but they somewhat ruin the intended energy of the story by ruining some of the mystery earlier than is ideal, which may make future reveals more underwhelming, and/or providing perspectives of people who are stuck in a wall, which kind of breaks the illusion of them being treated purely as objects.

If you want the extra smut, you can return and read the bonus chapters after reading the main story. Or, you can disregard this advice and read it all as it becomes available. Up to you.
