That's the purpose behind character developments. What's the point trying to develop characters if you're not going to explore into them and stick into the MC or main heroine solely? That's like saying Volume 21 which is Vali's volume should have zero focus on Vali and total focus on Ise.

Besides you say Rias is push aside? Did you consider that it's worst for Akeno & Koneko. At least Rias has one or two moments with Ise in almost volume. Akeno didn't even have any focus on her since Volume 7 to Volume 22, aside from the brief moment in Volume 14. Koneko wasn't focus on since Volume 5 to now, aside from the brief focus in Volume 11. In fact, Ravel wasn't even focus on till Volume 14, same goes for Rose till Volume 17, worst that's the only till she was in any memorable moment with Ise.

So you saying Rias is push aside is kinda nonsensical when you actually place consideration into other character's situation.
