I think the usage of 止める in the title might be the "to stop (someone from doing something)" definition. Something like Acro, Interferes feels like a more appropriate title for this chapter.
Anyway, thanks for your work, it's been quite nice being able to finally read this series
While there aren't any explicit supernatural elements, it is heavily implied by the total loss of control over their bodies. At least, I'd argue it goes far enough past what is considered possible under hypnosis that it reaches into the supernatural realm.
My pleasure, I read Doubt way back when OneManga was around and Tonogai-sensei has been among my favorite authors since then. I'm just glad to work on a series he did (even if it is the odd one out among his series).
Not a hiatus, around the start of December the author apologized on twitter for the recent delays and that he's on partial childcare leave, and around the New Year he said that December was hellish for him. In better news, chapter 67 has been scheduled for release next tuesday.
