You'll have to wait... longer
News of Coven and Labyrinth of Refrain by Nippon Ichi Sofrware says that the game has been delayed 2 months from it's initial release date for further improvements of the game and also to deliver the game at a higher quality as it is.
Coven and Labyrinth of Refrain is set in a town called Refrain, where a certain cursed labyrinth exists that takes the life of people who dare traverse in it. The player controls a legendary book called "Youro Rekitei", and together with a witch, your owner, you'll take on the task of exploring the labyrinth. With the player unable to fight, the witch will create dolls to fight for your stead.
It is interesting to mention that this game closely resembles Makai Kingdom, also a game by Nippon Ichi Software for the PlayStation 2 and PlayStation Portable, which features a protagonist that is also a "Book".
Coven and Labyrinth of Refrain was planned to be released on January 28, 2016 but was delayed and will be officially released on March 17, 2015 for the PlayStation Vita in Japan.
