That was great, one weird raw compilation, I have never seen that chapter 6 before, and it was AWESOME, cute and sweet, also there was no Tomomi chapter?, very estrange indeed.
I took a look at it and it says "to be continue" so I guess this series got popular and that chapter 6 is actually the continuation from this volume (If you take a look, there are 7 chapters plus extra and they considered chapter 7 as 6 for some reason).
Plus, you can see that there are some unresolved questions about Akiyama like what's with that amount of money he has?
