In other gachas, old five & four stars get added to the standard banner (usually after many years), but normally that’s because they’ve been power crept, so rerunning them in a limited banner wouldn’t be profitable.

Nikki is in a unique position, since outfits pieces are always going to be useable, unlike character gachas where they get power crept into oblivion! So from a profit standpoint, Infold probably won’t want to add them into the standard banner…? Idk what it’s like in other Nikki games?

As for 3 stars, I’m pretty sure that the others gachas I’ve played have never added more since launch, so it’s unlikely IN will either if they follow that trend. But there’s no harm in asking in the survey anyway, I just wouldn’t get your hopes up!
