@ker0 On the credits page I see you are using MS Paint to clean. I suggest you try out the tool "paint[dot]net". It is free while also having transparency, layers, and a bunch of other super useful tools while sill being super simple like MS Paint. You get the program at "getpaint[dot]net"
[dot] should just be a . but idk if links are allowed in comments so i thought it best to not make them them actual links
though if you need help with cleaning then I am down to try helping you out so long as it doesn't require any too extreme redrawing
looking through the last 3 chapters of this manga only 1-2 pages are at the level where I'm not confident if I would be able to redraw them
