FuRyu is releasing their upcoming PlayStation Vita RPG, Caligula, in Japan on June 23, 2016, and they’ve provided an update on the official website with bonuses that you can get for pre-ordering the game.

The first bonus is an original soundtrack that is made from nine different composers featuring nine tracks with vocals by μ (CV: Reina Ueda), along with the main track “idolatry” that is performed Mirei (CV: Eriko Nakamura) x Sweet P (CV: Emi Nitta) x Sone (CV: Yuka Otsubo) for a total of ten tracks.

The second bonus is a special visual booklet with illustrations by character designer Oguchi. It features comments and other information from the cast.

The third bonus is a pre-order exclusive swimsuit DLC for the members of the Return Group. You can see some of the samples in the above image.

And finally, the fourth bonus is an application ticket to get into a special Caligula fan event that will be held sometime after the release of the game. It’ll feature many special guests and presents to those that attend.

Caligula will release on June 23, 2016 for PlayStation Vita. You can read more in our earlier report about the prologue of the game, where you’ll be trapped in a virtual world.
