>>67520463In the anime K-On!, the girls only interact with their fathers offscreen, or their brothers with only Ritsu's younger brother being in the anime. Men are seen in the background in some scenes, but overall have no major role. Love Live is similar. Idolm@ster has a larger role, but the males are either male idols (rivals) or Producers/CEOs and either self-inserts for (You) or irrelevant to the story.
There are many anime which are not CGDCT where males play a role. Hololive is cgdct however.
