TLDR: Don't worry about skipped chapters. DevilBro is on top of things
. Also, this is actually Chapter 9.
Just an FYI for anyone reading this: the real Chapter 3 of this series was only posted on Twitter for whatever reason, meaning it was missed by many people, including myself initially, because we only looked at the pixiv album. As a result, the numbering for this series is still* all wrong post–Chapter 2. (“Chapter 3” is actually Chapter 4, and so on.) I've already made a report and explained the situation to DevilBro, and they're going to respect the correct numbering going forward, but if they upload a correctly numbered Chapter 11 before my report is accepted, then there will appear to be a gap between “Chapter 9” and Chapter 11, but I'm commenting to say don't worry, that gap won't be real. (Well, it will be real, but it will be between 2 and “3” (4), not “9” (10) and 11.) I hope that makes sense.
*It was initially even more wrong because the previous scanlators skipped all of the purple border chapters.
