TL;DR: I see some incoherency between old 1.02 version (the one I started playing long time ago) and the Steam Kagura's 1.05 patched version in the Summer Vacation Journal. Then started to contrast with the DLsite 1.06 (the latest at time of writting), thinking that the Kagura team may have censored/cut content from the JP.
However, after a 6 hour investigation that you can read in the spoiler below, I conclude that Kagura team just ommitted some incomplete H-scenes from the JP 1.06 version, avoiding player's confusion in not finding some event that doesn't exists yet. Note that these conclusions are derived from the 100% save file compatible only on the ENG version and the decryption of both image libraries, where blank thumbnails for the lacking H-scenes are found, pointing that they're not in the game yet (or not in the Memories journal, at least).
Have here a .rar patch that is not really necessary, as it only solves some wrong order on the title tags from the Memories journal. To be specific, Misaki 03 title has the numbers with a different tonality of pink compared to other titles, and Chitose 03 and 04 are mistakenly labeled as 02 and 03. There may be some bloat on the ENG version, but I'm afraid of telling anyone what to delete and the game giving errors due to that.
