Either that or full white-out. That's what you can expect from the stuff you buy from Fanza/Dlsite. A ploy to encourage readers to buy physical copy, perhaps? Melonbooks version got just black bars.
Still, You can expect an official uncensored (and possibly full version with Miku and Yotsuba's extra stories.) to be on sale at FF44 in Taiwan (Around Feb 2025).
I just realized: the artist releases sample with most of the content and only include Miku on the fully paid copy - We're basically paying for a Miku doujin
