Great news, I find a shame that the translations are so behind the Japanese releases but since there aren't a lot of volumes Yen Press can catch up a bit.
A month ago more or less chapter 24 was translated:
Spoiler for ch 24:
We see Watanuki is a middle school boy who has a delinquent group with some primary school kids as his followers
The chapter focuses on his relationship with Karuta, who is his SS.
I wanted to hug her when she looked so sad saying that Watanuki hates her and also when she started to cry after Watanuki told her that they're friends.
The current chapters in Japan are getting interesting too
Spoiler for ch. 38:
Like expected, history is changing and Karuta's attack doesn't happen. It's so refreshing to see the original characters again after that second arc.
But Ririchiyo's family is a pain and takes her away for her "safety"
