Melancholy of the Fourth Dimensional Institution

A piece of "entertainment", where Kenji Konishi and Susumu Hirasawa play the roles of spiritualists sharing tools by mail to exterminate sadness in the world. This song was made to explain the production process of How About Fuko?, which Hirasawa considered difficult for anyone beyond them to understand it. He also considers it the sort of thing that could only be created by Fuko Project, because they didn't take each other's character into account.
