Edit: Replaced with proper rip, previous one used wrong profile when converting ppm to jpg (apologize for this, but the batch rip is done long time ago), this should be more closer to raw now. The difference can hardly be seen by bare eyes, you only need to re-download this gallery if you are super hardcore on quality.

#225 of 2D Dream Comics. 2nd collaborated comic tank by 助三郎 & 筑摩十幸, the previous (黒薔薇の騎士) can be found here; and there should be more in the future. The latest title called 紅の盗賊姫レイア is now serializing on 2D Dream Magazine, guess it will no wonder adopted into comics. This tank is a collection of comics from both 白百合の剣士 and ヴァンパイアスレイブ.

bought it myself and directly ripped from:

If you have DRM free PDFs and not sure how to rip them, you can send them to me and I'll try to help.
