First of all, the main definition of main character is playable in the arcade game, so that Koharu is qualified. As for the story, we see that she has been recurring in every episode, unlike S4 members and other girls could be absent.

What ＠沢城珠凛 pointed is correct that production cost is a major reason. And for that, after Part 3 there would really be no excuse for the team to not introduce another main character in CGI lives.

Well then why not? Idol characters with glasses are rather few so why not praise that?

The main reason why most of us feel Koharu doesn't have proper treat, aside from no anime CGI live, is that:

1) In game marketing aspect, she seldom shows up in most ad artworks. Most promotional card feature Kasumi sisters and rarely highlight her as a sexy representive or a Romance Kiss user.

2) In order to promote game Part 2, they put Mahiru in the prior place when game Part 2 and its anime part. However this directly influences the movie plot so that Koharu cannot have a theatrical live scene, also not having own Step series coord.
