Is the password here any sort of english word?
What i mean is, it's pretty obvious what needs to be done to the file, and i'm a manga fan, so i got what the clue was about, even thought it gives you nothing to go on for actually completing the challenge, but even after i *do that thing with those parts of the file*, the text in the image is still unreadable, i've tried color-balancing, noise-reduction and all sorts, but its virtually impossible to make that word out.
Originally i thought it may be guessable by reading the wiki, but that yields no results either.
Yet another edit:
Oh well, i really should try harder before i post
Lesson learnt i guess
Turns out i was this -->| |<-- close, a little tip for anyone else, once you figure out what needs to be done, and what with, think a little bigger, like 2x bigger
