DDB-148 - Kimeseku Best

A common theme in this series is that their personality changes before and after the transformation. Perhaps because there's an agreement to go raw, the actresses seem to immerse themselves in the play with ease. As a viewer, seeing them expose their shameful side gives a strange sense of value for money. The premise itself is wild, but it definitely sets itself apart from other transformation-themed works. Also, since these older works are set during the daytime, there's no sense of guilt.
