コンパイルハート
The game is developed for the PlayStation Vita by Compile Heart, the creators of "Hyperdimension Neptunia". Originally slated for release in spring 2013, in November 2012 it was announced that the release would be moved up to January 24, 2013. The game includes artwork of legendary creatures re-imagined as girls from more than 50 different artists. An English localization for "Monster Monpiece" was announced by Compile Heart on January 21, 2014. On January 23, 2014, Idea Factory sent out a formal press release to address the issue of censorship in Monster Monpiece. The release dates for the localization was initially announced on May 9, with the game planned to be released on May 27 in North America and May 28 in Europe, however, the European release date was later pushed back to June 4; this was done in order to allow the game to be available in Germany, Russia, and Switzerland, where it was originally unavailable. Unlike the original Japanese version, the English localization is a digital-only title.
