When you open the zip file, you will find an ABR file. Take that file and deposit it in the Brushes folder in your Adobe Photoshop.
Programs > Adobe > Adobe Photoshop > Presets > Brushes
You have my permission to post, use, and/or renovate the brushes however you like. I do NOT own the rights to this line-art. These were clipped from scans from many different mangas. I did not draw any of it, merely cleaned, repaired and processed them into brushes. If you want to credit me for my efforts to make these into brushes you can, but it's not necessary.
