Chapter 15 was the first "proper" appearance, but her first introduction was in Volume 2 actually, which speaks for itself regarding the author's intention for her.
As far as intent goes Shiho was prob always meant to be a cornerstone of the story, given how her actions are the catalyst for literally everything the manga is about. If she hadn't left the band, Yori wouldn't've come in as an extra to help out for the performance, which means Himari wouldn't've seen her perform, they wouldn't've interacted or fallen in love, etc.
