That's how this gallery should look like. What's the point of uploading the still images from the game that's a compilation of animations from the previous games?
That's not all of them (still most of stuff) since I've converted all of them before I knew about the "less then 10mb" rule so I will add more after I find a way to make them less big.

Also out of these 31-36 are from Kozukuri Youkai H Henka, 55-60 are from Seeeki! Bukkake Bokujou! and 61-66 are from Touma Kojirou no Tantei File - all of those are already uncensored thanks to the official release from Mangagamer.

You could preserve frame smoothness and keep filesize low if you could bother finding the looping point in each animation and then cut off the redundant loops. See some of the gifs I made for Grandee games as an example. That's a lot of work though, so this is fine.
