Suspicious window

Monokuma brings in a large pane of light purple glass and places it as a divider in a certain corridor, Kokichi finds there's something weird with said, glass wall and calls Shuichi to come investigate with him.

I don't have a very good idea about how the school layout is in my head so I'm gonna make it up as i go so certain places might not exist, or look different in the game than its described here. Also the Monokubs don't exist in this universe, so yeah.

Enjoy
