I`m already looking through all 31 volumes.
I just finished vol.4
Oh easy going scans just translated ch.4, they may go to the end.
As to not stray from the topic, chapter 20 titled "the girl who brings good luck" that doll was so cute, I really hope she comes back.
Was she in the anime by any chance?
She appears here first in ch.20:
