many! it's hard to just dump them all so. incoherent ramble. depends what kind of white day au we're talking like princess saki and knight ichishiho or goddess saki or witch ichihona. all of them kinda exist as wd au in my head even though some of the events technically aren't wd but whatever. im basic i like princess saki and her knights with honami being able to fill a number of different roles. i just think the dynamic between pricness saki and knight ichishiho as her guards would be fun because they'd love each other so much but ichishiho would be too nervous to do much of anything because they think they can't because of their position. and also princess saki is just really cute lol. i also really like goddess saki i have a whole Thing im writing with goddess saki i wouldn't really call it a wd au since it doesn't have any of the other wd leoneeds but i like goddess saki a lot from a number of different points. my brain happens to be very fixated on her resurrecting leoneed right now though. aside from that i like the idea of wd saki having a whole arc going from princess to like disgraced knight to dying and becoming a goddess ive always had big ideas for how to write it but i probably never will :p
