There is a pre-existing set of raws for this ( https://e-hentai.org/g/833241/360479857a/ ), but the quality was, shall we say... poor. I re-edited them; they look much better now.

If you think that images that only need some leveling, cropping and occasionally could benefit from some rotating are poor quality then I guess you don't know what poor quality really is.

Also, if you're going to re-edit a perfectly fine gallery (in my opinion) then you should do it properly or don't bother at all.
You left a lot of blurry areas on the sides that you could've cleaned properly, for example left side of page 10, 14, 18, right side of page 11
You didn't level some pages properly, like Mikoto's skirt on page 10 which is still grey-ish and stands out or Touma's hair in the middle of page 18 and later pages where it's also grey-ish.

Images should be as released by the source. Conversions, "retouches", leveling, or removing original source watermarks do NOT count.
