The recently announced Kamigokuto Mary Skelter 2 is going to have a pretty peculiar pre-order bonus in Japan, in the form of a full-fledged romantic visual novel titled Koigokuto Mary Skelter (Love Prison Tower Mary Skelter).

The game basically pulls a reverse Muv-Luv move by placing the protagonists of the games within a school-basic romantic adventure context.

Today the publisher released a new video that includes the adorable opening cutscene of the bonus title, including the theme song “Michai Kyutton Tiiga Purite Gubanko” performed by Saori Kodama and composed by Takahiro Yamada.

The game will include full voice acting, dedicated visuals, CG events, and music, but Compile Heart doesn’t plan to release it separately in Japan.

You can watch it below, but be careful, it’s devilishly catchy. If you want to see more, you can check out the original announcement of Mary Skelter 2, including the opening cutscene and more, and the first gameplay trailer.

The Japanese release will come on June 28th for PS4. No announcement has been made for the moment for the west, but a localization is not unlikely since Idea Factory International might pick this up.
