HPR-004 Description

The concept of “催●契約” isn’t simply about destroying women in a simple manner. Instead, it involves enjoying the process of falling in love with someone in a game-like way. The DVD includes an audio commentary by the director, explaining the scenes from the “催●術師” selection. This commentary is included as a sub-track. ※For streaming, only the main audio will be available.
