Hey, I appreciate the translation!
I do see that you skipped the omake pages, but that's fine.
The weird part to me is how the chapters are structured in this series, with the first chapter stretching into volume 2. I'd have to imagine it wasn't originally serialized that way in the magazine, so it's kind of annoying that they decided to publish it that way in the tankobon instead of replicating the magazine's chapter structure.
Chapter 1 probably could have been broken up further, considering an omake page showed up in-between pages 146 and 148 (pg 50 & 51 in this upload). There was also a page that felt a lot like the final page of a chapter in the first half of Chapter 1 (pg 70).
If it was up to me, I would have split it up the first volume as such:
pg 001~012 - Prologue
pg 013~070 - Chapter 1 (part 1)
pg 071~094 - Chapter 1 (part 2)
pg 095~146 - Chapter 1 (part 3)
pg 147 - Omake (part 1)
pg 148~180 - Chapter 1 (part 4)
pg 181~182 - Omake (part 2)
Here are the raw omake pages from this first volume for anyone curious about what they looked like:
