What action is Yashiro supposed to take? In episode 3, Satoru tells his teacher to "hurry up" and do something about Hinazuki at the end of their conversation, and also states in the narration that he's "positive Yashiro is waiting until spring vacation before taking action."

I'm slightly confused. Yashiro earlier says that "the Child Consultation Center visited their house three times." I thus assumed that


The Child Consultation Center is already worried or suspicious (if they visited Hinazuki's home at all). Yashiro probably informed them about the abuse at Hinazuki's home. (Even if Yashiro didn't, they are already aware of the case.)
The Child Consultation Center would be the party responsible for any further follow-up or protective measures, not Yashiro.


Am I wrong about this? If I am not wrong, what is it that Yashiro must hurry up and do? (Does he simply need to speed up things, given that the Child Consultation Center is "so incompetent"?)
Satoru simply wanted him to do something, anything, to make sure Kaya would stay safe. He suggested calling the police and getting the counselors to check in again. Satoru wanted the teacher to speed up the process because he was planning to wait until the next school break (Spring, if I remember correctly.)
