We get this question quite a bit so it's always brought it up every time we discuss what things we need to do next. Unfortunately, because we're not specifically a H-centric group it gets relegated to the "SOON™" category. It really would be nice to see a completion on that story since it's pretty interesting, but the time we do have for translation is best spent on the main projects we do run.

Short answer: No?
Long answer: We did Houkago Play 2, 3, and R as standalone projects. While they may all be in the same universe, we never really intended to be the [singular] Houkago Play translator, it just looked that way. This is different than scanlating WataMote in which we try to be a series translator that does everything under the umbrella of the series.
So, did we "drop" Houkago Play? No, we never really picked up the series itself, but the individual volumes only.

It's synonymous with quality check, where you make sure there is no errors. Though, Meiru like to skip this or do it themselves which is why their releases have errors!
