That reminds me... some time back Coco was inviting practically every other member of hololive in Japan to come live in the holohouse. Several of them seemed interested, but I haven't heard if any had actually moved in.
R: "Alright, let's do this" knock knock
F: "Ugh, who could it be at this time of the century?" Opens "Ah! Onee-sama!? What are you doing here?"
R: "This is my house... Anyway, happy Valentine's, Flan. I love you (as a sister)"

^^ True; there's many anime that's got fan service, but like for a kickass anime like Symphogear and Lyrical Nanoha, which are well known, it's definitely got that super cute married couple feel rather than it building to some climax
While some holomembers have expressed interest, what we know for sure right now is that Coco and Kanata are roommates and Suisei and her sister (Anemachi) live in the apartment next door to them. More recently, Rushia moved to either another apartment in the same complex or to another complex that's close enough that she can drop by whenever.
