"It is almost hard to believe the blooming popularity of PC visual novels in the West. There was a time that the closest fans would get would be an anime adaptation or a translation through unscrupulous means. Now not only is the effort to bring visual novels official English releases, but there are even a few that are being released in English right alongside their Japanese release.
Such is the case with NEKOWORKs and NEKOPARA Vol. 1 which was released in English the same day it was available for purchase in Japan, offering both an all-ages version as well as an 18+ version. "
Was really surprised with how fun Nekopara ended up being. Fluffy and cute visual novels like this deserve some recognition, though I have a feeling it'll be a while before we end up seeing the second volume.
There is a way to patch the steam version with the +18 content but you need the jp version either digital or physical copy to do so.
