CG rip from the game ( http://www.getchu.com/soft.phtml?id=817004&gc=gc http://www.bootup.jp/products/hanitsuma/index.html ) and append disc.
Some of the original files are just a slightly modified parts of the full images, in game projected over those. I combined those, except for the ones being just faces/fluids (at times +5 similar images with just a different facial expression seems overkill; besides, it would take hours to create those additional ones as well. And you would have to play the game and keep a checklist to determine which face/fluid pic is used in combination with which regular pic). This saves others the effort to combine them themselves. Including the separate 'parts'(faces/fluids) images as well in this gallery seemed like a bad idea to me, that doesn't really enhance the viewing pleasure. I included those in a separate folder in the torrent for completion.

Update 2015-03-07: added 1 image that I forgot, but is in the torrent, 003, and images from the game's update 111(released 2015-03-02, http://www.bootup.jp/support/sup_hanitsuma.html ): images 666-668

This goes into the creepy, uncanny valley folder. I hope you know why.

I think this guy must be really, really, REALLY ugly brat. (like Ugly Bob from South Park) :D 85% of time gals are drawn with eyes closed. Ha, ha. Very weird.

Nice harem HCG but 'closed eyes' factor is a bit puzzling.

@Thrawnizator Read the uploader comment, he left out the other facial expressions.
