Kisekae are virtual "paper doll" toys, early dressup games popular with girls and women in the 90s/2000s. They were especially popular among anime fans, and many of the dolls created were anime and manga characters. I've done a quick look and I haven't seen any other kisekae pages on neocities so I thought I'd go ahead and add my own. I played the hell out of these toys when I was a young teen!
How to play Kisekae
Otakuworld has a collection of Kiss doll viewers. Direct Kiss 1.1.1 works for me on Windows 10. Otakuworld is the biggest resource for Kiss dolls out there that I know of! It used to be a paid subscription site but eventually as the fandom tapered off into nothing it was made free. There are hundreds of dolls available on the site for download.
Once you've installed a viewer, you need to download individual dolls. I've put together a collection of dolls that I personally adore and played with when I was younger. These are all downloaded from Otakuworld, linked above. Many of them are originally sourced from long-dead geocities and personal art pages. I did not create any of them and present this file only in an attempt at preservation.
