Blow your compilation complaints out your fucking asses; absolutely none of these chapters are available in Japanese on this site (only translations into other languages).
And expunging galleries is worthless, since they can still be accessed (pro-tip: advanced search options). Here's the expunged version someone else uploaded a long time ago: https://e-hentai.org/g/496141/cf2c3f3ab0/
AND IF YOU'RE STILL A LITTLE BITCH ABOUT COMPILATIONS, THEN WHY DON'T YOU DO EVERYONE A FAVOR AND BUY THE MANGA, SCAN IT, AND UPLOAD IT?
A point that comes to mind regarding naming is that tankoubons can have extra material, so it can be helpful for a gallery title to indicate it's collected-together rather than using the same format as a tankoubon title. (e.g. the 'Ch.1-10' I see in a different gallery's title at the moment.)
