>>4275796It's kind of the Japanese thing of respecting your superiors and not wanting to overstep boundaries for the chuubas themselves. Whatever small chuuba shares an artist with Fubuki or Kuzuha would get shamed as a leech if they just started spamming their relationship (see Uto to Amelia), but if the artist brings it together, it's a comfier atmosphere, as the artist of course commands respect regardless of anyone else's standing on their own. And seeing as they're the mother/father of everyone there, it's of course called a "family".
