@Ingraman Nothing definitive, but the official Japanese site for the manga (at least per the series page on ANN), seems to imply that the series is still on hiatus. Not that I can actually read any japanese, so I don’t know for sure, but it has what appears to be a list of manga chapters, with #57 & #58 being the most recent, and the latter dated 2/16/24, shortly before the hiatus started: https://storia.takeshobo.co.jp/manga/mahoako/
I also tried ANN’s link to the creator’s twitter account. Still nothing I could puzzle out for sure one way or the other, but I did spot a couple of posts from Oct 2024, about the same time the anime’s season 2 was announced. I’m not sure if that was actually the most recent posts, though; for some reason, nothing seemed to be in chronological order.
My best guess is that the author is still recovering in one form or another. I hope they’ve managed to recover enough to resume working, even if it’s recent enough that no one is ready to announce or publish anything new yet. But I’m not really finding anything either way.
