Hey! To answer to your question on the thread (if only we could have a private status update or something, so we wouldn't spam the public status with nonsense xD) : yes, both live limited! フロスチ was sold just before their hiatus (2015/12) and 雨降る夜に was (or still, I don't know) sold when they came back from the hiatus (2016/10). Pretty neat xD
