I think there's a misunderstanding of your read on the nature of this game and others like it. That misunderstanding is leading to you having unwarranted expectations of the writers and the direction of the project.Was going to post this in "content I want" in corruption of champions 2 area, but I feel this is better suited for here. Keep in mind this topic area is completely dedicated to talking about our "gripes" with the game. So the entire point of this thread is about fair criticsms. I feel I might get abit of hate for posting this, but please to the writer, the staff, and the fans, these are simply my opinions and nothing more. I have nothing but respect to the amazing writers of this game, and admiration. So with that being said, my criticism is largely to the story.
SPOILER CONTENT READ AT YOUR DISCRETION
1-Cait
The first companion we had and the person who is supposed to be the poster girl of this game has honestly been completely dethrone by kiyoko and the Kitsune content. At this point we might as well make kiyoko the poster girl of this game, for she has more sex scenes than anyone else, and her village has the most content out of anyone else. We literally get basically four wives out of the kitsune village. And most likely more in the future. Now I am not complaining at all about this, for Kiyoko is actually my literal dream wifeu, and if you were to paint my ideal perfect wife, it's kiyoko. So I am giving this criticsm DESPITE The kitsune content being my favorite part of this game. Cait is suppose to be the poster girl of this game, yet her father scene felt completely rushed and didn't even get her own dungeon for him. Like finding her dad should of been way more flashy. Just despite her being the poster girl of this game, I really don't see her getting any character growth as she just remains this unhinged nympho who will fuck literally anything that breathes. Honestly her unhingedness just kinda makes me think of. "She belongs to the streets" meme. Maybe that's the point of her character, but I just feel there is so much more we can do with this character. She's one of the driving forces to the plot and it just feels like the other wifeus in this game are simply more interesting.
If you're a developer, you'll want to have some form of art to advertise your project in a succinct manner. Something to visually represent the game. You can't use the player character, because that will vary greatly depending on the player of the game. Cait on the other hand is a character that EVERY PLAYER will interact with no matter what their choices are concerning her after she is introduced. She is a natural choice to put on an banner for the game because of that.
However, putting her on the banner is not a declaration from the developers that the game is about her. She features prominently in the storyline, sure. She's an important character. But the game is not About her. The devs owe no such content quota surrounding her as opposed to other characters within the script, and a characters representation relative to hers in the game does not make them more 'important' for the needs of a banner. While the game has many authors that write perfect waifu type characters, the game is itself also not about finding waifus like Cait or Kiyoko.
The problem you are critiquing is not a problem with the game. Its a problem of your expectations not matching actual intent in the project and being mislead by the needs surrounding banner advertisement.
That's to say nothing of when each character was developed, when the banner was created in relation to that development, when each character had an author sit down and write the necessary content for their addition into the game and more.
