Thank you for your the translation! From the Amazon.jp link the book is 288 pages, and in the index chapter 6 begins on page 203 while the afterword or extra begins on 280. Chapter 6A and 7/6B here on mdex are 47 pages so it seems like there's a gap of 30 or so pages left in the book? Is this Ch 7/6B really the end, or are those extra pages a different story? ): It's so sad and seems kind of abrupt for an ending. (Just sad if that is the ending, not complaining about your hard work!)
