Well this is Kurosaki's show, his the main protagonist so his always going to be involved one way or another.
Yeah that's true but SS plays a huge part as well, Ichigo can be involved but if SS does nothing it'll seriously make no sense. Come one Kubo, I'd really love for SS to take this one, it's about damn time.
