I discussed this with Shosuke Yuu, one of our translators, and we came to an agreement that there isn't any pages missing. You are probably thinking that the two pages that follow up Chapter 6 are part of it, but actually they are part of Chapter 6.5 (I know, this is confusing but their context is clearly part of Chapter 6.5 and NOT part of Chapter 6). We use Tankoubon scans (I buy them digitally to avoid the tedious scanning process). Later we will start to use magazine scans once we catch up with the latest chapters (this won't happen anytime soon though, with our curent speed it will take months to get there).
Ah, okay. Some mangas do this and it's a bit confusing, I'll admit. I assumed they were part of chapter two and that the cover page with 6.5 marked the beginning of chapter 6.5. I was going to wait until the next scanlated chapter to see if maybe this was the case, but I figured I'd ask anyway. Thanks for the clarification!
Thanks to the scanlation group working on this. Since you guys don't have an official page, I just wanted to point out that there seems to be two missing pages at the end of this chapter. I'm not sure if you're working with tank or magazine scans, so it might be different in the magazine, but the tank shows that there are two pages in this chapter before it gets to chapter 6.5. Just wanted to let you know or maybe you were adding it to the next release. Anyway, many thanks again for working on this manga!
