#229 of 2D Dream Comics. Replacing this improper rip, and this downscaled. There is an English translated version, which is pretty neat in quality, tho it is a bit downscaled, just wondering why nobody else put up better quality ones, so I bought it myself and ripped it from:
http://www.dlsite.com/books/work/=/product_id/BJ008898.html/
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.
