I've cleaned all these up and made them as pretty as possible since I know you want to use these pictures for projects.
I'm also being a shit and giving you a volume at a time.
First Up Saiyuki Manga Volume One Select Scans (Filesize 2,492 / Images 10):
The Picture of Kanzeonbosatsu is HOT!!!!!
I'd do her, Him, IT!
(I'm Sure you know already that She/He is Both. Female on Top, Male bottom.. right?)
Next up The best bits from Volume Two!
Hope you like these, let me know if you want me to scan bigger I can no problem.
