Underspin - Literally just underswap but w/ the storyshift pairs (y'know, Sans <-> Papyrus, Toriel <-> Asgore, Chara <-> Asriel, Napstablook <-> Mettaton, Undyne <-> Alphys) The main difference is Chara <-> Asriel, which is something that always irked me.

Also, isn't there an au which is like reverse storyshift?
