This is the digital artbook bundled with the Progear no Arashi Sound & Art Collection CDs by SuperSweep, converted from the main PDF into high quality 350PPI PNGs, I already uploaded it here but there was some quality loss in the conversions, HUGE thanks to Elemhunter [https://e-hentai.org/uploader/Elemhunter] for helping me a ton in figuring out the measurements I should use during conversion, hopefully the inflated filesizes aren't a bother, enjoy!
Excellent archival work, good sir. Furthermore, good job following up on your previous one of lower quality and increasing the quality significantly. You are the sort of uploader this site needs.
