I remember seeing this posted on these forums a while back by funkyobrian. Here is the post i am referring to.
"Critical Volume told me of this anime he saw from over a decade ago where this gal gets into a fight with a salamander man. She does some magic to shrink him and swallow him. As she's gloating victoriously the salamander man inflates inside her, causing her to inflate until she bursts. It sounds like an awesome scene from what Critical told me but he doesn't remember the title of the anime. All he remembers is that it was subtitled, featured late one night on a cable network, and had a style somewhat similar to Clamp."
That was posted over 6 years ago. Has anyone actually found this scene yet?
I think that is one we will never find, since the details are just too obscure =S
